Greetings.

I've been running my PC (Windows 7) just fine until now. I have two Western Digital hard drives set up in a RAID with about 500 GB capacity total. The hard drive is partitioned into C: (~465 GB) and D: and E: (each about 10-15 GB) After I got a new video card (details in next paragraph) I noticed that the other two partitions of the hard drive were simply...gone. I have absolutely no idea why this has happened, and would love your help.

About a week ago my computer stopped booting. The monitors were blank though the system was trying to boot, and the motherboard (ASUS P5W DH Deluxe) made one long and three short beeps -- according to (http://www.bioscentral.com/beepcodes/awardbeep.htm) this is the code for a bad video card. I replaced the video card and it was only after this I noticed that the other partitions were gone. I do not know if the partitions disappeared before or after the video card fault.

I'm scared that this is a motherboard problem of some sort, which would be bad.

Oddly enough the system remains stable: it functions perfectly aside from the missing partitions and there are no errors of any sort. There isn't any very critical data on D: or E:, but I'd like my data and my partitions back. :thumbsup:

Can anyone help?

System Specs:

PC: Homebuilt
OS: Windows 7 Ultimate 32-bit (acquired via university)
Motherobard: ASUS P5W DH Deluxe
CPU: Intel Core 2 CPU 6600 @ 2.4 GHz
RAM: 4096 MB

Old Video Card: evea GeForce 8800 GTS
New Card: evea GeForce 9500 GT

Final Note: If the Motherboard isn't bad, I'd like to exchange the new video card for a better one -- the 9500 GT sucks.

Are you running them in RAID 0 or 1? And do they appear under disc management? (if you dont know how to open it, just go to your search bar and type computer management, click on it, there should be a option called disc management) In disc management it should show all the available hard drives and partitions. Please note, you will have to be logged in as an administrator of the computer to do this.

The partitions do not appear in disc management. As for Raid 0 or 1, to be honest I forget -- how do I check up on this? And thanks.

should probably say in the BIOS. Or if you remember-are they striped (2 hard drives combined into one big hard drive) or mirrored (same information is written to both drives)

The RAID BIOS should reflect the drives...if all is well.

I'd start there.

I believe it's Raid 0 -- will check the BIOS shortly.

EDIT: I checked both the BIOS and the RAID BIOS -- the partitions are not visible. Gremlins are to blame.

Well, to be honest, at this point, It sounds like the array got corrupted-and the solution that comes to my mind is to reformat it and see if that fixes the problem. However, that being said, Im far from an expert on RAID, and if you want to hold off a bit and see if someone who knows more about RAID offers a suggestion, it couldn't hurt.

I'd rather not format -- the copy of Windows 7 I have was an ultra-cheap university distribution that's only good for two installs. I may just have to live with the missing partitions unless there's some way to get them back unobtrusively. Still, I think I'm going to back up data...
