I installed Windows 7 Home Premium 64-bit on the SSD and I activated raid0 on the two 1Tb disks for programs and documents.
Everything was fine for 1 month until last Monday.
Day 1 - Monday August 16
I was playing Company of Heroes for those how know it and I decided to pause to go eat. When I get back, the game is now in windowed mode although it was fullscreen before and the colors are all messed up. I quit the game but since my PC is slow, I reboot. While booting, I get this message at the raid0 screen:
The booting continues since Windows is on the SSD and once I get to Windows, I try to go in my raided disks and it works fine. I can read my files, watch my videos and listen to my music. However, when I try to open Steam, which is a program to launch games like Company of Heroes, it doesn't work. Nothing happens and there is no message. I shutdown my PC but it's stuck on Windows's logoff so I hard shutdown. Since my hard disks are in the hot-swap bay, I switch the two 1Tb and I boot. This time the "Error Occurred" is on top so I suppose it means that the problem is really on the hard disk and not in cables or on the port. I shutdown my PC since I have to go to work and I put back my disks in their original spot.
Day 2 - Tuesday August 17
I boot my PC and I install the Western Digital diagnostic software but I can't seem to get infos on my disks and I think it's because of the raid0. I backup all my data on another external disk. I un-raid my disks and I format them. I don't raid them again and I put the programs and my games on the disk I believe to be the functional one (the one on top in my case) and I put my documents on the disk I believe to be the defective one (the one on bottom). Everything works fine during all the morning. I test with the Western Digital diagnostic software and both disks give no errors. I slowly transfer all my documents on the "defective disk but once I try to transfer a big video file, the copy seems to get stuck in the middle. I cancel and I try again many times with that file and other big files with no success. I shutdown my PC and this time Windows shutdowns correctly.
Day 3 - Wednesday August 18
I boot my PC and I try to copy my big problematic files of yesterday and it works. Later, all my files are back on my "defective" disk. After dinner, I start watching a video of about 45 minutes in length and after a while, the video freezes and I can't access to that disk. It starts to work again a couple of minutes later and I can finish the video in multiple segments because the same problem come back and disappear a couple of times. I tried to test with the Western Digital diagnostic software at the exact second the video was freezing and the diagnostic seemed to get stuck at the beginning but after a couple of minutes it was starting and finishing without errors. I shutdown my PC.
Day 4 - Thursday August 19
I boot my PC and I don't really use it. I only check if my disks are all there and if I can access to the files and everything looks fine. I leave my PC for the morning and when I come back after diner, the documents disk is gone. I can't see it in Windows and it seems like it unmounted. I shutdown my PC.
So, anyone else had a similar problem? Am I right to believe the problem is on the disk and not a cable or a port? Why is the Western Digital diagnostic software never giving any error? Since it takes a while to start to bug, can it be related to heat? I tried using the Asus Probe software but there is no temperature for disks. Is there something else to do than buy another disk?
I'm having a similar issue with my 2TB WD Caviar Black, I checked the file system for errors and looked for bad sectors (right click the drive, then properties, then tools and error-checking), it didn't fully work for me but it might work for you.
You have checked your cable and power connections to your hdd's,,etc ???,,,. I had a similar problem with "bad blocks" across three relatively new WD hdd's, anyhow turned out it was one of my removable caddies was snafu'ed, replaced same problem gone,so far...
Just a thought , would not your hdd's be somewhat corrupted if your ram were pants, because hdd read/writes are DMA???
