Steam - How To Fix Disk Write Error
  1. My first thought was that it was referencing a hard drive problem, but if it does this only with that file, I would say it's more likely a file problem. It sounds like Windows is not able to write or possibly read from the properties values in the file. If it's a MP3, you could try running it through a audio editor like Audacity, then re-saving it.

    However, if you get that with most all audio files, even ones you know to be good, it could be related to hard drive access. If you suspect that, you might run CHKDSK on your hard drive, defrag it and make sure it's not getting too full. I like to keep between 1/4 to 1/3 of the drives capacity as freespace, though with bigger drives, you can reduce that.

  2. The ID3 tag, attached to MP3's, allows users to specify song title, artist, album, etc. As of ID3 disc error occurred during write operation, extra information could be added such as images and comments. But with this extended information came the ability to also attach viruses, malware and file locks to an mp3. Some websites such as www.2conv.com and www.flv2mp3.com use the extended format of ID3 v2 to disallow users from removing their information from the comments section or their associated image from a downloaded file.

    If you have access to an ID3 tag editor (not merely the values allowed in Windows Media Player or Windows Explorer), you will be able to see the lock on the mp3 file that throws the "a disk error occurred during a write operation" error and remove it.

    If you cygwin fetchmail server certificate verification error have access to an ID3 tag editor, the easiest way is to use iTunes:
    • Load the mp3 into your iTunes library
    • Right click on the song and choose "Convert ID3 tags."
      (Note - this option only appears from the library selection, not from playlists)
    • Convert the ID3 tag to v1.0 - this will remove all extended information from your track such as hidden add-ons, malware, images and file locks
    • Convert the ID3 tag back to a v2 format so you can add your own extended data (I like v2.3)
    • Right click on the song and use the "Get Info" option to add whatever information you want
    Once you've converted the ID3 tag to v1 and back, you will have effectively removed the extended data that prevents changes to the original file, and you will be able to change properties, modify data, rename the file, etc via Windows Explorer without the write error.

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, disc error occurred during write operation. 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, disc error occurred during write operation. 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 fagor fus6116 c03 error 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 razr v3i error 35 02, 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 run time error 217 windows 7 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 disc error occurred during write operation well on that computer, you can superficially make a preliminary judgment on cables as well as the hard drive's health condition, disc error occurred during write operation. If that computer can boot bad image error Windows without prompting "A disk read error occurred Press Ctrl + Alt + Del to restart", the problem lies in your disc error occurred during write operation 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 disc error occurred during write operation 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, disc error occurred during write operation, 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

Please note that you should select BIOS version based on your operating system, version, system board model, etc. Usually, the Opera $.ajax error 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.

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", disc error occurred during write operation 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, disc error occurred during write operation, 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 disc error occurred during write operation recovery window.
