A Disk Read Error Occurred in HP Computer [Solved]

My HP laptop says “A disk error occurred”

“Hi, I have a problem with my HP computer that runs Windows 7. Whenever I boot up it, I see a black screen with the message – A disk read error occurred Press Crtl + Alt + Del to restart appearing. I have never encountered such a problem and don’t know what to do. Is there any advice? Thanks!”

Reasons account for the error

To fix “A disk error occurred” in HP laptop or desktop accordingly and effectively, it is necessary to realize the possible reasons for this error and the main elements are concluded as follows:

► The BIOS is outdated.
► There is something wrong with the BIOS settings.
► The hard drive cables are failing.
► There are bad sectors on the hard drive.
► The MBR of the hard drive that holds operating system is corrupted.

Five solutions for A disk error occurred

As you have realized the possible reasons for “A disk error occurred” in HP, it is time to learn how to solve this problem. Here four valid ways are listed.

Solution 1. Update the BIOS version

Outdated BIOS can cause “A disk read error occurred”. At this time, you can upgrade the BIOS to the current version: Download the latest BIOS version from the manufacturer website to a bootable device > install the BIOS for your HP computer from the bootable device. After that, reboot your HP computer to see whether the error disappears.

Solution 2. Reset the BIOS settings

This way can be applied when the error is caused by BIOS settings issues. Here are detailed steps:

1. Restart your HP laptop or desktop.

2. Enter BIOS Setup menu by pressing a certain key as the prompt.

3. On the BIOS Setup screen, choose and load the BIOS Setup Default settings by pressing a certain key.

4. Save changes and follow the prompt to restart the computer.

Solution 3. Check hard drive cables

A disk error occurred in Windows 7 can be a result of failing hard drive cables, thus you can check the hard drive cables to see if there is a loose cable connection. If the power cable is worn out. If not, you can connect the cables to different ports to see whether the ports are damaged. If the ports and cables are OK but the error still exists, it is time to consider whether there is a problem with the hard drive.

Solution 4. Repair Master Boot Record (MBR)

When the error in HP is caused by corrupted MBR, you can rebuild MBR to fix this error. Here two ways are offered and you can choose one based on your specific situation.

#1. Fix MBR on Windows 7 from Command Prompt

If you are with Windows Installation CD/DVD, you can boot from it, enter Recovery Console and go to Command Prompt. Then, run the following commands:

▪ bootrec /fixmbr
▪ bootrec /fixboot
▪ bootrec /scanos
▪ bootrec /rebuildbcd

#2. Rebuild MBR via AOMEI Partition Assistant

When you are no Windows CD/DVD, you can turn to AOMEI Partition Assistant Standard, which enables you to fix MBR simply. Let’s see how it works:

First of all, create a bootable USB drive with AOMEI Partition Assistant on a working computer. Then, follow the steps below:

Step 1. Insert the bootable media created by AOMEI Partition Assistant to the unbootable HP computer and boot from it.

Step 2. In the main interface of AOMEI Partition Assistant, right-click the disk needs repairing and choose “Rebuild MBR”.

Step 3. Choose the MBR type and then click OK.

Step 4. Click Apply >Proceed to perform your operation.

Solution 5. Check hard drive for bad sectors

When the system disk is with bad sectors, the “a disk read error occurred” message can show up as well. If so, you can use AOMEI Partition Assistant to check the hard drive for bad sectors. Start with the following steps:

Step 1. Boot from the bootable media created by AOMEI Partition Assistant or remove the hard drive from the unbootable computer and connect it to a working computer and run AOMEI Partition Assistant.

Step 2. In the main interface of OAMEI Partition Assistant, right-click the disk needs testing and choose “Surface Test”.

Step 3. Tick “Quick Check” and click “Start” to check.

PS.: When there is a bad sector on the hard drive, it might be marked as a red box.

Wrap things up

When you encounter “A disk error occurred” in HP laptop or desktop, you can figure out the reason for this error at first and then take solutions accordingly. If necessary, you can ask the help of a third-party disk manager– AOMEI Partition Assistant. Apart from rebuilding MBR and test hard drive, it enjoys many other useful functions like migrating OS to SSD, copying hard drive, and so on.

Summary

This article discusses the Stop error messages that can occur when you try to install Windows Vista. This article describes the possible causes of each Stop error message. It also provides troubleshooting steps for each issue.

INTRODUCTION

This article discusses several Stop error messages that may occur during the installation of Windows Vista. It also discusses possible causes of the Stop error message and steps to resolve the problem.

If you receive a Stop error message when you try to install Windows Vista, it is important to collect and to document as much information as possible about the error. The specific error code and the parameter information can help determine the appropriate troubleshooting steps and resources.

More Information

You may receive any of the following Stop error messages when you install Windows Vista.

Note If the Stop error message is not listed, and you can start the computer, run the Microsoft System Diagnostics Tool (MSDT) to collect the Stop error message information.

Stop: 0x0000007B

A "Stop: 0x0000007B" error message indicates that Windows Vista or Windows Vista Setup cannot access the hard disk that contains the Windows Vista startup files. Typically, this Stop error occurs when Windows Vista cannot locate a compatible driver for the disk controller device. For example, this Stop error can occur if Windows Vista cannot locate a compatible driver for a RAID controller.

You may also receive this error message if one or more of the following conditions are true:

  • The hard disk is faulty.

  • The hard disk cabling is faulty, or the hard disk cabling is not connected correctly.

  • The computer is infected with a boot sector virus.

  • The computer BIOS or the disk controller firmware are incompatible with Windows Vista.

  • Another program is using the master boot record.

If you receive this Stop error message during a clean install of Windows Vista, it typically means that Windows Vista does not include a compatible driver for the disk controller device. To resolve this issue, you must provide a compatible driver during the installation of Windows Vista. To do this, follow these steps:

  1. On another computer or in a dual-boot configuration, download a compatible driver for the disk controller device.

  2. Save the driver that you downloaded to an optical disk or to a removable USB drive.

    Note If you are running a dual-boot configuration, you can also save the driver to a local hard disk.

  3. Start the Windows Vista Setup from the Windows Vista DVD.

  4. When you are prompted to select the disk on which to install Window Vista, select the Load Driver option.

  5. Follow the prompts on the screen to complete the installation.

If you receive this Stop error message when you try to upgrade to Windows Vista, it also typically means that Windows Vista does not include a compatible driver for the disk controller device. However, it also means that the driver that was used in the previous operating system is incompatible with Windows Vista. Therefore, the driver cannot be reassembled and migrated for use in Windows Vista.

If you receive this Stop error message when Windows Vista tries to restart during Windows Vista Setup, follow these steps:

  1. Restart the computer.

  2. Roll back the installation to the previous operating system.

  3. Check with the disk controller manufacturer for information about the issue. If no additional information is available, download and install the most recent driver that is available.

  4. Try to upgrade to Windows Vista again.

    Note If the issue persists, perform a clean installation of Windows Vista, and use the Load Driver option that is described earlier in this section.

Stop: 0x000000A5

A "Stop: 0x000000A5" error message typically indicates that the computer BIOS is incompatible with the Advanced Configuration and Power Interface (ACPI) standard that is supported in Windows Vista. However, this error can also occur because the computer hardware, the peripherals, or the drivers for those devices are incompatible with Windows Vista.

If you receive this error message when you install Windows Vista, follow these steps:

  1. Restart the computer.

  2. Roll back the installation to the previous operating system.

8 Solutions to Troubleshoot A disk read error occurred. Press Ctrl+Alt+Del to restart Error

When you have a problem while using your computer and you receive an error message during a crash, you’re hoping the message will point toward the cause and then it can be appropriately rectified. This doesn’t always happen though and the message can be rather generic and the fix isn’t exactly a straightforward affair with a clear place to start troubleshooting.

Unfortunately, there seems to be many errors you could encounter on your system that sound straightforward but lead to the same problem, the error message isn’t accurate enough for you to make a clear decision about what to do next.

A while back I had a problem with my computer, and after some odd things happening such as a CD-R failing a burn and the computer starting to respond very slow, I decided to shut it down and leave it for a while. When I booted it up the next day, I got the error message:

A disk read error occurred. Press Ctrl+Alt+Del to restart.

However, the BIOS detected the hard drive just fine. After an exhaustive search around the Internet and forums, no one had the exact fix for this problem and there doesn’t seem to be one fix to try in preference to any others.

A disk read error occurred

What makes this even worse is there are so many different ways to attempt to fix this error, it could take days to get through them all. And to make matters worse, a disk read error might not actually mean there’s a problem with the hard drive itself! Also there seems to be just as many software causes as hardware causes.

Listed below are some of the possible solutions we came across to fix the “A disk read error occurred. Press ctrl+alt+delete to restart” problem.

1. Test the Memory

This isn’t actually mentioned that much around the web as a solution to the disk read error problem, but believe it or not, this was my problem. I used a tool called Memtest86+ and ran tests on my RAM, and indeed there were problems. After experimenting between different sticks and RAM slots I eventually deduced my RAM slot 2 was damaged because the sticks worked fine in the other slots.

memtest86

As this is a simple and non destructive test meaning you’re not touching the hard drive risking further damage, it is recommended you try this first. It may sound odd but in fact memory problems can be responsible for a vast array of different errors on a system where testing your RAM might be the last thing you think of.


2. Try the Drive on Another Machine

As we’ve said, although this problem sounds like a simple hard drive issue, people around the web have reported that they have traced the problem to faulty video cards, modems, motherboards and even power supplies. The easiest way to rule out any of these is to take the hard drive out and connect it up to another machine or connect it to the same machine via external USB. If you can boot it up past the error or can access all your files without a problem, then the issue will likely be related to other hardware in your machine.

Unfortunately in this case it could be down to trial and error in finding the offending piece of hardware by removing or replacing what you can, although the next possible fix is quite easy.

While the drive is connected by another method, it’s recommended to run a scan with something like HD Tune to test for any bad sectors. Whether HD Tune finds any issues or not, you should also run a “chkdsk drivename: /r” from a command prompt while you’re able to or use a portable tool to do it for you.

It’s also wise to make a backup of your files or the whole drive while the drive is accessible.


3. Check / Replace Cables

Although I haven’t seen SATA cables fail (but obviously they can), faulty IDE cables can sometimes cause issues such as read or write errors on hard drives as well as optical burners. If you have spare cables, you can replace them, or unplug the current cables, inspect for damage, and then reconnect them if OK. Also try different SATA or IDE ports if you can as there is a possibility of a damaged port.

If you get the disk read error after installing a new drive, make sure the hard drive is on the master connector (end of the cable) and if you can, set the hard drive jumper to master instead of cable select. Also try without a secondary (slave) device attached to the same cable if there is one.


4. Resetting / Updating the BIOS

In rare circumstances setting the BIOS back to defaults can fix the issue. You can usually get to the BIOS by pressing Del or F2 etc during boot. There should be an option to reset to defaults, look for an option similar to the one in the picture below. Failing that, you can remove the BIOS battery for a few minutes to reset. If you’re unable to access CMOS because it is password protected, you can easily reset it from Windows by using CMOS De-Animator.

Updating to a newer BIOS has also been reported to work, especially on laptops.

We have several more possible solutions to the disk read error problem on page 2.

Solved: Disk Read Error

One of our subscribers recently sent us a mail regarding an error that was related to disk read. His system was not able to read the disk and thus preventing the system from booting the Windows. He told us that when he pressed the power button to turn on his laptop - instead of seeing Windows loading screen, a pitch black screen as shown below was displaying 

“A disk read error occurred

Press Ctrl + Alt + Del to restart”

He was more worried about the data stored on the drive and was scared if the disk had failed. We were eventually able to help him out by providing him with relevant solutions that worked for him and he got his data back.

The problem was with the boot sector of his system and he had to fix the boot and MBR (Master Boot record) file. However, it’s not the case with everyone. Below we have explained the troubleshooting techniques, which will fix the probable causes of this issue. However, if none of the following works for you, we will help you recover your data from a corrupt, inaccessible, or damaged disk too.

Unplug any USB or DVD drive

Remove all storage devices connected to your system including DVD drive, USB stick, or an external hard disk. It’s possible that your system is trying to boot from one of the connected devices due to modification in boot priority. Alternatively, you can enter BIOS and change boot priority order and set it to internal hard drive.

Reset/Update Your BIOS

Resetting BIOS can help fix the disk read error by restoring your system’s default settings. This also fixes any other issue related to hardware.

To reset BIOS, follow these steps:

  1. Restart the system and keep tapping the setup key (try F2 or Delete key; refer user manual to know the exact key) to enter BIOS. 
  2. Choose Load Setup Defaults or similar option that says apply defaults or load default settings, factory settings, etc. 
  3. Hit Enter to reset BIOS. Choose YES when prompted to confirm BIOS reset. 

Alternatively, you can also try to update your BIOS to fix disk read error. You should always keep an eye on your BIOS updates and keep your BIOS updated to the latest version.

Fix MBR and Fix Boot

This solution did work for our subscriber and so you can also try to see if it works for you too. This works when your system’s boot sector or MBR (Master Boot Record) gets corrupt or damaged. For this, you need a Windows installation or repair disc. You can also create one using Windows ISO and a tool like Win32DiskImager.

Use it to boot the system and then,

  1. Select the language 
  2. Click ‘Repair your computer’ link at the bottom-right corner of the window 
  3. Choose the OS (Windows OS version) you want to repair, and then click ‘Next’ 
  4. From the System Recovery Options window, choose ‘Command Prompt’ 
  5. Run CHKDSK utility by typing chkdsk X: /r where X is the drive letter (This will check the disk for errors and will fix them) 
  6. After Chkdsk finishes, type Bootrec /fixboot to repair the Boot Sector 
  7. Then type Bootrec /fixmbr to fix the Master Boot record file 
  8. Type Exit and then click Restart

Check your hard drives’ cables

Don’t forget to check your hard drive’s SATA and power cables (IDE) in case of a disk read error. Check if they are loose or defective by testing the cable’s using a Multimeter device. This Multimeter device is available at any electronic repair shop. Replace the cables with new ones if they fail the continuity test.

Test RAM memory

It’s rare but sometimes RAM (Random Access Memory) issues bring various problems such as application crashes, blue screen of death (BSOD), data corruption, and disk read error. That’s why you should run a memory test quarterly or monthly to detect any issue with the RAM. The test is easy; doesn’t harm your RAM and helps you fix the disk read error.

Step 1: Download Memtest86, a free standalone memory testing utility that allows you to check your system memory for issues at hardware-level. You can run various tests after booting your system using a Memtest86 bootable USB drive.

Step 2: If you have recently added a new RAM, remove it and restart your system to check if the error still exists. You can also swap (change) RAM slot and check if the issue is fixed by rebooting the system.

Try the Drive on another Machine

If you have tried all the solutions and none of them worked, take out your hard drive and connect it to a different PC or laptop. You can also try connecting it to the same PC via USB port and use BIOS to select the drive as a bootable drive in the boot priority order.

This will help you find out if your hard disk is corrupt and damaged or if there is a major hardware problem with your PC like many people reported who traced the issue to a faulty video card, motherboard, and even power supply.

If the disk is detected on another or same PC via USB connection, run CHKDSK utility to scan and repair bad sectors and other issues with the hard disk.

In case this solution also doesn’t help, it’s confirmed that your hard disk is corrupted due to internal errors caused by bad sectors or the drive has failed. If the hard drive is still under warranty, you can reach your hard drive manufacturer and ask for a replacement or RA (Return Authorization).

Please note that you will lose all your important data stored on the hard drive as manufacturer won’t offer any guarantee of data safety and recovery of data from the corrupted hard disk. Therefore, you need a professional data recovery tool like the Stellar Windows Data Recovery – Home that can help you recover your data from an inaccessible, severely corrupt, and formatted hard drive with ease. Any logically damaged hard drive’s data can be recovered using this tool’s ‘Deep Scan’ feature.

Conclusion:

You may have probably fixed your system’s Disk Read error by following the above given solutions. In some rare cases, when a hard drive fails or gets severely corrupt, you need to replace the hard drive. That’s where you can take the help of Stellar’s Data Recovery tool that we mentioned. With its powerful data recovery algorithms, this tool helps you recover almost any type of file like pictures, videos, audios, important Office documents, compressed files, or RAW data.

Description and symptoms of read disk error

A disk read error occurred is a common error that we can encounter. This error means Windows detects a hard disk problem or there is something wrong with the process of reading hard disk. This error appears while computer boots up and blocks computer to boot into operating system, directly preventing user out of system. It appears with message "A disk read error occurred Press Ctrl + Alt + Del to restart" as picture below. When you press Ctrl + Alt + Del to restart computer you still get same error without being able to boot up Windows.

A disk read error occurred Press Ctrl + Alt + Del to restart

Here is one of such questions related to disk read error from customers:

"Hey All! I did a system update for my computer. The download and installing process went well, but when I restarted computer I got an error on the black screen saying "A disk read error occurred Press Ctrl + Alt + Del to restart". I restarted computer for several times and all ended up with this prompt. I have used this laptop for nearly 5 years and never had a disk read issue. I can't do anything with it, as I can't access Windows 7. Is there something wrong with the hard disk or system update? Is it possible to fix it if I reinstall Windows using installation CD? Do you have better solutions on this issue?"


Why does disk read error occur?

The actual cause of this error varies from computer to the other, as it ranges from hardware issue to software problem. This section makes a summing up of the most common reasons behind the disk read error.

Computer hard drive fails

In most cases, the read disk error indicates hard drive damage. When boot sector on hard drive is damaged or system partition gets bad sectors, then system booting will be stuck with errors.

No bootable hard disk

Sometimes, the disk read error occurred before system booting is the result that computer read wrong bootable hard disk. If there is no bootable hard disk or the bootable is not properly configured, system won't be able to boot normally.

Hard drive cables damage

The IDE cable is the wide piece of wrings in your computer case and it is responsible for connecting hard drive and motherboard. Occasionally, incorrect or loose IDE cables can lead to read or write errors on hard drives.

BIOS setting issue

In rare cause, disk read error caused by improper BIOS settings. When BIOS updates are available, you should update it carefully.

MBR is corrupted

Incorrect or invalid Master Boot Record setting is another common cause. Furthermore, corrupted MBR configuration can be caused by virus attack, power outage, bad sectors, etc. Besides, misconfigured partition table might bring about this issue.

Sudden power failure

Improperly shutting down system is likely to corrupt files and hard disk on your computer. This typically happens if power is cut accidentally or system is forced to shut down in order to kill an unresponsive program. After computer crashes, Windows will ran a check for file system and disk while booting with the purpose of verifying and repairing problematic files.

Operating system issue

The incomplete or improper installation of Windows also gives rise to this issue, such as system is lacking of dll files or some system registry files are damaged.


Fix "A disk read error occurred" on Windows

Since reasons behind this error are varied, there is no set solution to fix this issue. We provide a couple of different solutions so that you can try out to fix this problem on your own.

Solution 1: Test RAM memory

This is seldom regarded as a solution to fix the disk read error issue, but it works in some situations. Because a faulty RAM slot or RAM slot may result in the problem. It sounds odd that testing RAM has something to do with hard disk read error, but memory problem indeed brings about various issues. Since the RAM memory test is easy and non-destructive, you may as well perform a complete test for RAM memory. The entire test process is safe and doesn't damage hard disk or data, you can try this first.

A disk read error occurred Press Ctrl + Alt + Del to restart

If you added new RAM memory to computer in recent days, you can try to remove it and leave only one RAM. Then restart computer and to view whether the issue is eliminated.

Also, you can move the single RAM module to the other slot to check whether RAM slot is damaged. To do so, you can leave one RAM module on one slot and restart computer. If disk read error still occurs, move the RAM to the other slot and start computer again.

Additionally, you can use third party tool to run the test. Burn the tool to your bootable CD or USB drive, and then it can diagnose RAM after computer is booted to CD or USB disk.


Solution 2: Check / replace hard drive cables

Hard disk cable might be broken, leading to system can't read disk correctly. To rule out this possibility, you can do this: try a new or different port for IDE or SATA cable. If there is more than one hard drive connected to computer, you should unplug all disks except the one from which operating system boots. Then you can check whether the cable or post is damaged. If you get the disk read issue after a new disk is installed, you need to make sure the disk is on the master connector if possible and set the disk jumper to master. If cables on your computer are damaged, you should replace them with new ones.

Another way to check hard drive cables is moving the affected hard drive to another working computer. If hard drive works well on that computer, you can superficially make a preliminary judgment on cables as well as the hard drive's health condition. If that computer can boot into Windows without prompting "A disk read error occurred Press Ctrl + Alt + Del to restart", the problem lies in your computer instead of the hard disk.


Solution 3: Reset or upgrade BIOS

Installing an incorrect or incomplete version may trigger serious issue, thus you should upgrade BIOS very carefully. Plus, restoring BIOS to default setting or upgrading can fix this issue in some circumstances. How to do that?

Reset BIOS

Step 1  Restart computer and press the key which enters BIOS setup. The key might be F2, F10, Del, etc. varying from computer to computer. Just look carefully at the screen while computer starts.

Step 2  Use arrow keys to switch menu options and locate the option to reset BIOS. The name to revert BOIS to default settings is not the same on different computers, which can be Load Fail-Safe Defaults, Apply Default, Load BIOS Defaults, Load Default Settings, Load Setup Default, Factory settings, etc.

A disk read error occurred Press Ctrl + Alt + Del to restart

Step 3  Save changes, exit BIOS and restart computer.


Upgrade BIOS

Go to the website of your computer's manufacturer and find the Download center where you can download the latest BIOS version. Please note that you should select BIOS version based on your operating system, version, system board model, etc. Usually, the BIOS download comes in a compressed file such as .zip file. When you extract data from it, you can see a README file which will guide you through the upgrading.


Solution 4: Rebuild MBR (Master Boot Record)

table for the disk, disk signature as well as executable code called master boot code. When computer boots, BIOS codes identifies startup disk and reads MBR. If MBR is damaged or corrupted, you will not be able to boot system or even lose partitions. How to rebuild MBR? Here we can use DiskGenius Free to rebuild MBR. DiskGenius is a free partition manager designed to manage disk and partitions and recover lost files and partitions. It provides free features to rebuild MBR, repair partition table, resize partition, edit hex data, etc. Let's see the steps to rebuild master boot record.

Since the affected computer can't boot to Windows, you need to boot computer with bootable disk.

Step 1  Create a bootable disk for DiskGenius. Run DiskGenius on another normal computer and insert a USB flash drive to that PC. Select the flash drive and click "Tool" menu to choose "Create WinPE Bootable USB Drive of DiskGenius". Click "OK" to confirm the operation.

A disk read error occurred Press Ctrl + Alt + Del to restart

Step 2  Insert the bootable disk to the computer that reports disk read error and power on PC.

Step 3  Press the key that can enter BIOS immediately where you can set the bootable disk as the first boot. Save changes and restart computer.

Step 4  Now computer will boot from the USB disk and enter DiskGenius Dos version by itself.

Step 5  Select the hard drive from which you want to boot computer and click "Disk" from menu to choose "Rebuild Master Boot Record". Click Yes on the popped-up message box.

A disk read error occurred Press Ctrl + Alt + Del to restart

Solution 5: Verify and repair bad sectors

Bad sectors are sectors on storage devices that are physically or logically damaged and cannot be read or written by operating system. You can test hard drive by viewing S.M.A.R.T. information or checking bad sectors with disk tools. If computer can't boot to Windows, you can boot computer with bootable disk. In that case, please create DiskGenius Bootable disk following step 1~4 in Solution 4. Alternatively, if you have other bootable disk, you can copy the installation folder of DiskGenius to the bootable disk.

Step 1  Launch DiskGenius and select the disk that says disk read error, and then click "Disk" to choose "Verify or Repair Bad Sectors", as follows:

Step 2  Click "Start Verify" button on the "Bad track verification" window and DiskGenius starts scanning bad sectors. As shown in the screenshot below, red blocks are damaged, representing bad sectors. Time taken by the verifying process depends on the capacity of select hard drive, please wait patiently.

A disk read error occurred Press Ctrl + Alt + Del to restart

Step 3  If the hard drive contains bad sectors, you should back up important files to another disk and try repairing bad sectors with DiskGenius.


How to rescue data while disk reads error?

Hard disk read error should be attached great importance, for it not only prevents system from booting, but also sometimes gives rise to data loss. As mentioned in previous part, corrupted MBR may lead to partition and data loss; bad sectors can change partition into inaccessible. Can you recover lost data while partition cannot be opened or hard drive is empty and contains no partition? This section is going to introduce an easy method to recover files from corrupted and inaccessible partition.

Step 1  Run DiskGenius and locate the partition that needs recovering data. The click "File Recovery" button from the tool bar to open file recovery window.

Step 2  Select "Complete Recovery" option and click "Start" button. To recover deleted files, you should select "Recover Deleted Files Only". File scanning might long of the partition being scanned is of large capacity. You can preview files during scanning when files are displayed.

A disk read error occurred Press Ctrl + Alt + Del to restart

Step 3  Preview recoverable files. You can preview file's original content by double clicking it. File preview can help judge whether files can be recovered correctly and successfully, because it identifies whether file has been damaged.

Step 4  Recover files. Select and right click files you want to recover and choose "Copy to". Then you can choose a location to save recovered files.

  6. After Chkdsk finishes, type Bootrec /fixboot to repair the Boot Sector 
  7. Then type Bootrec /fixmbr to fix the Master Boot record file 
  8. Type Exit and then click Restart

Check your hard drives’ cables

Don’t forget to check your hard drive’s SATA and power cables (IDE) in case of a disk read error. Check if they are loose or defective by testing the cable’s using a Multimeter device. This Multimeter device is available at any electronic repair shop. Replace the cables with new ones if they fail the continuity test.

Test RAM memory

It’s rare but sometimes RAM (Random Access Memory) issues bring various problems such as application crashes, blue screen of death (BSOD), data corruption, and disk read error. That’s why you should run a memory test quarterly or monthly to detect any issue with the RAM. The test is easy; doesn’t harm your RAM and helps you fix the disk read error.

Step 1: Download Memtest86, a disk error occurred vista, a free standalone memory testing utility that allows you to check your system memory for issues at hardware-level. You can run various tests after booting your system using a Memtest86 bootable USB drive.

Step 2: If you have recently added a new RAM, remove it and restart your system to check if the error still exists. You can also swap (change) A disk error occurred vista slot and check if the issue is fixed by rebooting the system.

Try the Drive on another Machine

If you have tried all the solutions and none of them worked, take out your hard drive and connect it to a different PC or laptop. You can also try connecting it to the same PC via USB port and use BIOS to select the drive as a bootable drive in the boot priority order.

This will help you find out if your hard disk is corrupt a disk error occurred vista damaged or if there is a major hardware problem with your PC like many people reported who traced the issue to a faulty video card, motherboard, and even power supply.

If the disk is detected on another or same PC via USB connection, run CHKDSK utility to scan and repair bad sectors and other issues with the hard disk.

In case this solution also doesn’t help, it’s confirmed that your hard disk is corrupted due to internal errors caused by bad sectors or the drive has failed. If the hard drive is still under warranty, you can reach your hard drive manufacturer and ask for a replacement or RA (Return Authorization).

Please note that you will lose all your important data stored on the hard drive as manufacturer won’t offer any guarantee of data safety and recovery of data from the corrupted hard disk. Therefore, you need a professional data recovery tool like the Stellar Windows Data Recovery – Home that can help you recover your data from an inaccessible, severely corrupt, and formatted hard drive with ease. Any logically damaged hard drive’s data can be recovered using this tool’s ‘Deep Scan’ feature.

Conclusion:

You may have probably fixed your system’s Disk Read error by following the above given solutions. In some rare cases, when a hard drive fails or gets severely corrupt, you need to replace the hard drive. That’s where you can take the help of Stellar’s Data Recovery tool that we mentioned. With its powerful data recovery algorithms, this tool helps you recover almost any type of file like pictures, videos, audios, a disk error occurred vista, important Office documents, compressed files, or RAW data.

How to Fix It When A Disk Read Error Occurs

  • Run a desktop clean up utility. This removes any files that could cause a memory error. Although, the errant file could be a symptom of more serious issues, cleaning up the desktop is good for maintenance.

  • Defrag the computer. In certain circumstances, this could fix the issue. You may have to connect the HDD to another machine to perform the defragmentation and then boot from it.

  • Test the RAM. A problem when booting could be the result of problems with the computer's memory. You can use Windows Memory Diagnostic by entering mdsched into the Windows Search (or Start Search) box and pressing Enter. The tool runs automatically when you restart the computer. Alternatively, there are several free memory test programs you could try.

  • Check the cables. Loose connections or faulty cables can cause issues with booting as well as hard drive errors. Look for disconnected cables. If possible, swap out the cables with spares. At the very least, disconnect them, inspect the cables for any damage, then reseat them securely, a disk error occurred vista.

  • Test the hard drive. This could mean removing the hard drive from your current machine and plugging it into a working computer, where you can scan for bad sectors. This could help determine whether the issue is repairable or if you a disk error occurred vista a new hard disk drive (HDD) and a fresh install of Windows.

  • Reset the BIOS. Reverting the BIOS to defaults could resolve the issue. Access the BIOS at startup and look for an option to load BIOS setup defaults, which could be one of the following or similar:

    • Load BIOS Defaults
    • Load Default Settings
    • Load Fail-Safe Defaults

    Alternatively, update the BIOS version to the latest available.

  • Reseat the computer's RAM. Due to heat, the RAM can wiggle its way partially out of the slot, triggering a memory error.

  • Replace the RAM. Or, a disk error occurred vista, if there are two RAM modules in the system, interchange their slots.

  • Rebuild the boot sector. When you are unable to start the computer and see a disk read error, the boot configuration data store (BCD) could be corrupt, missing, or incorrectly configured. In addition, a disk error occurred vista, use the Bootrec.exe tool to troubleshoot other startup issues. For instance, the fixmbr command allows the repair of a corrupted or damaged Master Boot Record, and the fixboot command writes a new partition boot sector.

  • Rescue data. In some cases, a severely corrupted or failing hard drive might need to be replaced. If this is the case, you could recover files, even if the computer doesn't start. Although it might take some effort, using a data recovery program could save important files.

  • Fixed – "A disk read error occurred Press Ctrl + Alt + Del to restart"

    Description and symptoms of read disk error

    A disk read error occurred is a common error that we can encounter. This error means Windows detects a hard disk problem or there is something wrong with the process of reading hard disk. This error appears while computer boots up and blocks computer to boot into operating system, directly preventing user out of system. It appears with message "A disk read error occurred Press Ctrl + Alt + Del to restart" as picture below. When you press Ctrl + Alt + Del to restart computer you still get same error without being able to boot up Windows.

    A disk read error occurred Press Ctrl + Alt + Del to restart

    Here is one of such questions related to disk read error from customers:

    "Hey All! I did a system update for my computer. The download and installing process went well, but when I restarted computer I got an error on the black screen saying "A disk read error occurred Press Ctrl + Alt + Del to restart". I restarted computer for several times and all ended up with this prompt. I have used this laptop for nearly 5 years and never had a disk read issue. I can't do anything with it, as I can't access Windows 7. Is there something wrong with the hard disk or system update? Is it possible to fix it if I reinstall Windows using installation CD? Do you have better solutions on this issue?"


    Why does disk read error occur?

    The actual cause of this error varies from computer to the other, as it ranges from hardware issue to software problem. This section makes a summing up of the most common reasons behind the disk read error.

    Computer hard drive fails

    In most cases, the read disk error indicates hard drive damage. When boot sector on hard drive is damaged or system partition gets bad sectors, then system booting will be stuck with errors.

    No bootable hard disk

    Sometimes, the disk read error occurred before system booting is the result that computer read wrong bootable hard disk. If there is no bootable hard disk or the bootable is not properly configured, system won't be able to boot normally.

    Hard drive cables damage

    The IDE cable is the wide piece of wrings in your computer case and it is responsible for connecting hard drive and motherboard. Occasionally, incorrect or loose IDE cables can lead to read or write errors on hard drives.

    BIOS setting issue

    In rare cause, disk read error caused by improper BIOS settings. When BIOS a disk error occurred vista are available, you should update it carefully.

    MBR is corrupted

    Incorrect or invalid Master Boot A disk error occurred vista setting is another common cause. Furthermore, corrupted MBR configuration can be caused by virus attack, power outage, bad sectors, etc. Besides, misconfigured partition table might bring about this issue.

    Sudden power failure

    Improperly shutting down system is likely to corrupt files and hard disk on your computer. This typically happens if power is cut accidentally or system is forced to shut down in order to kill an unresponsive program. After computer crashes, Windows will ran a check for file system and disk while booting with the purpose of verifying and repairing problematic files.

    Operating system issue

    The incomplete or improper installation of Windows also gives rise to this issue, such as system is lacking of dll files or some system registry files are damaged.


    Fix "A disk read error occurred" on Windows

    Since reasons behind this error are varied, there is no set solution to fix this issue. We provide a couple of different solutions so that you can try out to fix this problem on your own.

    Solution 1: Test RAM memory

    This is seldom regarded as a solution to fix the disk read error issue, but it works in some situations. Because a faulty A disk error occurred vista slot or RAM slot may result in the problem. It sounds odd that testing RAM has something to do with hard disk read error, but memory problem indeed brings about various issues. Since the RAM memory test is easy and non-destructive, you may as well perform a complete test for RAM memory. The entire test process is safe and doesn't damage hard disk or data, you can try this first.

    A disk read error occurred Press Ctrl + Alt + Del to restart

    If you added new RAM memory to computer in recent days, you can try to remove it and leave only one RAM. Then restart computer and to view whether the issue is eliminated.

    Also, you can move the single RAM a disk error occurred vista to the other slot to check whether RAM slot is damaged. To do so, you can leave one RAM module on one slot and restart computer. If disk read error still occurs, move the RAM to the other slot and start computer again.

    Additionally, you can use third party tool to run the test. Burn the tool to your bootable CD or USB drive, and then it can diagnose RAM after computer is booted to CD or USB disk.


    Solution 2: Check / replace hard drive cables

    Hard disk cable might be broken, leading to system can't read disk correctly. To rule out this possibility, you can do this: try a new or different port for IDE or SATA cable. If there is more than one hard drive connected to computer, you should unplug all disks except the one from which operating system boots. Then you can check whether the cable or post is damaged. If you get the disk read issue after a new disk is installed, you need to make sure the disk is on the master connector if possible and set the disk jumper to master. If cables on your computer are damaged, you should replace them with new ones.

    Another way to check hard drive cables is moving the affected hard drive to another working computer. If hard drive works well on that computer, you can superficially make a preliminary judgment on cables as well as the hard drive's health a disk error occurred vista. If that computer can boot into Windows without prompting "A disk read error occurred Press Ctrl + Alt + Del to restart", the problem lies in your computer instead of the hard disk.


    Solution 3: Reset or upgrade BIOS

    Installing an incorrect or incomplete version may trigger serious issue, thus you should upgrade BIOS very carefully. Plus, restoring BIOS to default setting or upgrading can fix this issue in some circumstances. How to do that?

    Reset BIOS

    Step 1  Restart computer and press the key which enters BIOS setup. The key might be F2, F10, Del, a disk error occurred vista, etc. varying from computer to computer. Just look carefully at the screen while computer starts.

    Step 2  Use arrow keys to switch menu options and locate the option to reset BIOS. The name to revert BOIS to default settings is not the same on different computers, which can be Load Fail-Safe Defaults, Apply Default, Load BIOS Defaults, Load Default Settings, Load Setup Default, Factory settings, etc.

    A disk read error occurred Press Ctrl + Alt + Del to restart

    Step 3  Save changes, exit BIOS and restart computer.


    Upgrade BIOS

    Go to the website of your computer's manufacturer and find the Download center where you can download the latest BIOS version. Please note that you should select BIOS version based on your operating system, version, system board model, etc. Usually, the BIOS download comes in a compressed file such as .zip file. When you extract data from it, you can see a README file which will guide you through the upgrading.


    Solution 4: Rebuild MBR (Master Boot Record)

    table for the disk, disk signature as well as executable code called master boot code, a disk error occurred vista. When computer boots, BIOS codes identifies startup disk and reads MBR. If MBR is damaged or corrupted, you will not be able to boot system or even lose partitions. How to rebuild MBR? Here we can use DiskGenius Free to rebuild MBR. DiskGenius is a free partition manager designed to manage disk and partitions and recover lost files and partitions. It provides free features to rebuild MBR, repair partition table, resize partition, edit hex data, etc. Let's see the steps to rebuild master boot record.

    Since the affected computer can't boot to Windows, you need to boot computer with bootable disk.

    Step 1  Create a bootable disk for DiskGenius. Run DiskGenius on another normal computer and insert a USB flash drive to that PC. Select the flash drive and click "Tool" menu to choose "Create WinPE Bootable USB Drive of DiskGenius". Click "OK" to confirm the operation.

    Solution 5: Verify and repair bad sectors

    Bad sectors are sectors on storage devices that are physically or logically damaged and cannot be read or written by operating system. You can test hard drive by viewing S.M.A.R.T. information or checking bad sectors with disk tools. If computer can't boot to Windows, you can boot computer with bootable disk. In that case, please create DiskGenius Bootable disk following step 1~4 in Solution 4. Alternatively, if you have other bootable disk, you can copy the installation folder of DiskGenius to the bootable disk.

    Step 1  Launch DiskGenius and select the disk that says disk read error, and then click "Disk" to choose "Verify or Repair Bad Sectors", as follows:

    Step 2  Click "Start Verify" button on the "Bad track verification" window and DiskGenius starts scanning bad sectors. As shown in the screenshot below, red blocks are damaged, representing bad sectors. Time taken by the verifying process depends on the capacity of select hard drive, please wait patiently.

    A disk read error occurred Press Ctrl + Alt + Del to restart

    Step 3  If the hard drive contains bad sectors, you should back up important files to another disk and try repairing bad sectors with DiskGenius.


    How to rescue data while disk reads error?

    Hard disk read error should be attached great importance, for it not only prevents system from booting, but also sometimes gives rise to data loss. As mentioned in previous part, a disk error occurred vista, corrupted MBR may lead to partition and data loss; bad sectors can change partition into inaccessible. Can you recover lost data while partition cannot be opened or hard drive is empty and contains no partition? This section is going to introduce an easy method to recover files from corrupted and inaccessible partition.

    Step 1  Run DiskGenius and locate the partition that needs recovering data. The click "File Recovery" button from the tool bar to open file recovery window.

    Step 2  Select "Complete Recovery" option and click "Start" button. To recover deleted files, you should select "Recover Deleted Files Only". File scanning might long of the partition being scanned is of large capacity. You can preview files during scanning when files are displayed.

    A disk read error occurred Press Ctrl + Alt + Del to restart

    Step 3  Preview recoverable files. You can preview file's original content by double clicking it. File preview can help judge whether files can be recovered correctly and successfully, because it identifies whether file has been damaged.

    Step 4  Recover files. Select and right click files you want to recover and choose "Copy to". Then you can choose a location to save recovered files.
