Something Wrong With Hard Drive

Yesterday, I was running Prime95 to test the temperature of my CPU. About 10 minutes into the test, my computer restarted and when it was attempting to boot, it began to run some sort of tests which failed. The screen shots below show what I was looking at. It did this several times. Today, I turned on my computer, it ran the test shown in the 3rd screen shot and it said it corrected some errors then booted up. I didn't get a chance to take a screen shot of that though. Does anyone know what happened?

P.S. I recently setup RAID 0. I think it setup correctly, but I'm not sure.

re:

Your drive should not have lost data - but your raid array has become corrupted some how and needs to be recreated exactly how you originally set it up.

Re-create the array and you should be good to go.
 
Thanks for your quick reply. Does this mean I need to reinstall my OS? What might cause this type of corruption? I'd like to avoid this in the future if possible.
 
re:

Recreating the array shouldn't lose your OS so it should just boot straight back up after it's finished building. It's all dependent on how you originally set up the array. I'd use an external dock and backup the important personal data off the drive prior to re-establishing the array, just in the off chance you do have to reinstall the OS.

Corruption of raid array's could be caused by the following:

1. A physical fault with the drive, I.E... Bad Sectors
2. Could be caused by logical I/O errors when writing data to the disk.
3. Power surge
4. Raid parity can become corrupt due to System Crashes, or hard resets (without using the OS shutdown function).
5. Uncorrectable bit errors which cause bunches in the magnetism of the disk, which in turn prevents data from being stored within that portion of the disk.

I'd recommend if you haven't already, use a surge protector on your power supply and also follow good practice and never hard power off your PC (That's if you do it). I'd recommend once you rebuild the array, run a program like HDD Regenerator v1.51 and do a thorough scan of your disk for bad sectors (caused by physical damage). If none appear using this program, then it's safe to say that it isn't #1 above but potentially a bad write or system crash that caused the raid array to become corrupt.

Hope that helps. There's a lot of other reasons why it would corrupt but these are the most common reasons.
 
Thank you very much for your detailed answer. I actually didn't know about the hard reset. I've done it quite a few times actually, but I certainly won't anymore.

As for building my array, all I did when I set it up was go into my bios > Integrated Peripherals > RAID Config and then I enabled "RAID Enable", "SATA 1 (A0)" and "SATA 2 (A1)". After that it took me to RAID setup which is shown in the screen shot below. I don't remember changing anything on this screen because it was all setup this way when I first entered it. After that I installed Windows Vista and the RAID drivers during the install.

Which part of the above steps is the actual creation of the array? What should I redo in order to create it?

re"

That's the correct way of creating the array. You did say above that it was originally working, but after a test and a restart or two it appeared with those above faults.

I say follow the same practice as what you did when you first set it up, and hopefully things just fall into place. Let me know if everything goes according to plan when you recreate the array.
