raid error occurred

Do you have the Intel Rapid Storage Technology utilities installed? That should allow you to check the disks and clear the error. I had a bad SATA cable which caused an "Error Occurred(0)" message to appear on one of the member disks. I replaced the cable and everything works fine now. An unknown error occurred while running this application. If the problem persists, please restart the user's computer or try reinstalling the application. raid error occurred

Failed Disk 0 Controller 0 in Raid 1 Array error

The Precision T Desktop Workstation may display a "Failed Disk 0 Controller 0 in Raid 1 Array" error on boot. This error has been reported on T systems configured with two 1 TB SATA hard drives using the onboard Intel SATA RAID controller. The error occurred on the initial boot of the systems.

Steps to take to resolve the error

The error appears to be a result of the hard drive in port 0 losing the RAID configuration on boot. A possible workaround to this issue has been reported to Dell involving the steps below:

  1. Shut down the system. Open the computer case and disconnect the hard drive from the HDD0 SATA port on the system board.
  2. With this hard drive disconnected, reboot the system.
  3. When the system has finished booting, shut down the system and disconnect the hard drive from the HDD1 SATA port on the system board.
  4. Power on the system with both these drives disconnected.
  5. When the system has finished booting, shut down the system and reconnect both hard drives back to their original ports on the system board.
  6. When the system is powered on, raid error occurred, it should now recognize both hard drives correctly without the error and raid error occurred begin rebuilding the RAID 1 array, raid error occurred. At this point the system should be able to boot fully into the operating system.

Refer to the section for Removing and Installing Components in your Precision T owner's manual for assistance in connecting and reconnecting the hard drives.

Repair raid after bad suspension (Error Occurred 0)

In my case, Intel falsely accused one of my SSDs of failing.

To ensure this, you can boot a Live Linux USB/Disk (Ubuntu, Fedora, etc), using the GNOME Disks utility you can perform Extended S.M.A.R.T. Self Tests on the individual disks, raid error occurred. On a relatively modern SSD this will take less than an hour to complete.

If there are no issues with Windows booting, you should be able to install and startup the Intel Rapid Storage Technology driver/application. Select the Manage tab and then click the drive showing an error or warning icon. There should be an option to select "Mark as normal."

The POST BIOS/UEFI warning should go away after this.

Raid 1 Error Occurred

Posted 25 March - AM

Over a year ago, I bought two Seagate TB SATA hard drives, and set them up in Raid 1 (mirroring), so as to have a (slightly) more secure data storage system. Two days ago, I turned on my computer, and the raid status (Intel raid) had changed to Rebuild. This had happened a couple of times before, so I thought nothing of it. When it booted to windows, a windows driver install window came up, notifying me that there was a driver needed to be installed called "Duplicate" or something like that (could have been Rebuild, or something else along those lines). This was a bit more odd in my experience. I still thought nothing of it however. It installed the driver, and told me that windows needed to restart in order for the changes to take effect, or something along those lines. Being in raid error occurred a hurry, I told it to cancel (or wait, or something like that), and continued using the computer as normal for the rest of the day, raid error occurred. Come nightfall, I turned off the computer. The next morning, I turned on the computer, and the raid status screen had changed. On one of the drives, the message "An error has occurred" had appeared. The overall raid status was still on Rebuild. Since then, I have used SeaTools and SpinRite to individually verify both drives (without raid turned on) were in operational condition, and without errors. I tried booting from the boot drive in the raid configuration (which was not the one with the error), and it worked fine (the driver window still showed raid error occurred though). I couldn't see the other drive though (I had turned off raid at this point). I have tried changing ports, though not cables. Where should I go from here? Thanks in advance.

Raid 0 - Error Occurred (0) Help Please.

Hey guys, I have looked around google for my answers and I am pretty sure I need to send one of my hard drives back but I wanted to consult with my fellow forum members first about the situation I am having.

So basically I noticed the problem when I overclocked my system to Ghz, which I think was stable as I ran prime95 for a good 13 hours, raid error occurred. But when I loaded up Left 4 Dead, it crashed about 20 minutes in giving me the BSOD. On rebooting there was an error shown within my RIAD array showing this.

I noticed this was obviously not right, yet my system booted and was fine for "normal" raid error occurred (I put my system at its default clocks).

Anyway my system is fine, accept when I am gaming and it just does the same as before and crashes during game. The sound goes first like it can't process it fast enough and then crashes. I have ran the "HD Tune Test" and there is no bad sectors, yet when reading around raid error occurred have ran a program called "Intel Matrix Console" so I ran this program and it showed this.

So from what others have said I believe I have to replace the broken hard drive.

If this is true I was wondering weather I could take an ISO image of my current system and then just get a new hard drive and then burn it to my new RAID array.

I hope you guys can clarify my current problem and any help is greatly appreciated, I am going to head of to bed now as I have been trying multiple things and I need sleep, so I will read your responses tomorrow :)


Hi, raid error occurred, Lussi! Thank you for your reply!

Hi, raid error occurred, in my modest opinion this is not the forum for your problem, but i am a newbee here.

Hey, I'm a newbie, too, but allow to me explain my decision to post this in the "Software and hardware tools" subforum. You see, my thread isn't intended to solve the hardware problem of why the drives keep failing; I'm deliberately waiting to hear back from Western Digital support before I try to move forward on that issue.

Instead, with this thread I'm hoping to find a software tool of some kind that can reset the "Error Occurred(0)" flag, so posting here in the software thread seemed like the best decision. But if you have a suggestion for a different subforum to use, I'm eager to hear it. :)

In case of hard drives are ok you can enter to RAID setup utility at boot by pressing control+I or control+S or something similar and make a volume rebuild, i think.

Unfortunately, although this is a pretty new mobo (ASUS ZA) with the latest UEFI BIOS, raid error occurred, when I use Ctrl-I to enter the Intel Rapid Storage Manager ROM configuration settings, the only options available for my RAID 0 array are: (1) - Create a new RAID array; (2) - Delete an existing RAID array; and (3) - Reset all disks to non-RAID. There is NO option to rebuild the array (or to reset the "error occurred" flag).

Try updating intel raid drivers. A bug in old drivers caused me a similar case in a 5 HDD RAID5 a few years ago. Solved updating drivers.

Right now, the Intel RAID driver is the very latest available. I updated it fairly recently, but it didn't solve any problems.

But again, thank you very kindly for your reply and your valuable suggestions!

Recovering a RAID 0 Volume Failure Using Intel® Rapid Storage Technology

When a RAID 0 volume fails or is disconnected, the data on the hard drive is no longer accessible. 

If a hard drive is disconnected, you may be able to recover the volume. If a hard drive fails, you cannot recover the data. Refer to the appropriate procedure below to recover or re-create your configuration:

How do I recover a disconnected hard drive?

  1. Turn off the computer.
  2. Reconnect the hard drive.
  3. Turn on the computer. The option ROM automatically marks the RAID 0 volume as normal.

How do I re-create a failed hard drive?

This procedure deletes the failed RAID 0 volume and creates a RAID 0 volume.

  1. Turn off the computer.
  2. Replace the raid error occurred hard drive with a new hard drive of equal or greater capacity.
  3. Turn on the computer. When prompted during system startup, press Ctrl+I at the same time to enter the option ROM user interface.
  4. Click 2. Delete RAID Volume.
  5. Use the up or down arrow keys to select the failed RAID 0 volume.
  6. Press Delete to delete the volume.
  7. Press Y to confirm the deletion.
  8. Click 1. Create RAID Volume and follow the prompts to create a RAID 0 volume.
  9. Click 6. Exit.


After you use the BIOS setup of a Windows 7-based computer or a Windows Vista-based computer to change the Serial Advanced Technology Attachment (SATA) mode of the boot drive to use either the Advanced Host Controller Interface (AHCI) specification or redundant array of independent disks (RAID) features, you receive the following error message when the computer is restarted:



This issue occurs if the disk driver in Windows 7 or Windows Vista is disabled. This driver must be enabled before you change the SATA/RAID mode of the boot drive.

Alert icon Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly, raid error occurred. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

How to back up and restore the registry in WindowsTo resolve this issue, enable the AHCI driver in the registry before you change the SATA mode of the boot drive. To do this, follow these steps:

  1. Exit all Windows-based programs.

  2. Click Start, type regedit in the Start Search box, and then press ENTER.

  3. If you receive the User Account Control dialog box, click Continue.

  4. Locate and then click one of the following registry subkeys:



  5. In the pane on the right side, right-click Start in the Name column, and then click Modify.

  6. In the Value data box, type 0, and then click OK.

  7. On the File menu, click Exit to close Registry Editor.

More Information

During the Windows 7 or Windows Vista installation process, any unused storage drivers are disabled. This behavior speeds up the operating system's startup process. When you change the boot drive to a driver that is disabled, you must enable the new driver before you change the hardware configuration.

For example, assume that you install Windows Vista or Windows 7 on a computer that contains a controller that uses the driver. Later, you raid error occurred the SATA mode to AHCI. Therefore, the drive must now load the driver. However, you must enable the driver before you make this change.

This issue affects only the boot drive. If the drive that you change is not the boot drive, you do not experience this issue.

AHCI provides several features for SATA devices. These include hot plug functionality and power management functionality.
