Hi,

a few days ago i bought a new motherboard: asrock gs 31 r2.0
the problem is, in my old motherboard i had two seagate drives of 750 gb in RAID 0. I thought it would be ok to just put everything in my new motherboard including the two seagate drives.
Turns out it wasn't a good idea. i needed some important files from my raid array but the new motherboard doesn't support raid. so i put everything back on my old motherboard to copy all files to a 1tb disk. when i booted, all i got was a bad cmos error. so i fixed it but when i booted all i got was a blinking underscore. i took my windows 7 dvd and booted to the recovery console and launched diskpart. it still recognizes my array: status: online, size: 1397 GB, free: 0 B. 0 bytes? when i pressed list volume i only get volume 0: ltr: C, Label: none, Fs: RAW, size: 698 GB. Any help is REALLY appreciated.

When you connected the two disk drives to the new motherboard, what else did you do? Did you try to install an OS onto one of them?
nope. i TRIED to boot once though and all i got was an error: "missing operating system"What was your old motherboard?I think it is an Acer mcp73e. Would it help if i just bought a raid CONTROLLER and place it on my new motherboard? The REASON you're having problems is that your old board had an Nvidia chipset whereas your new one has an Intel chipset.
You can normally migrate RAID arrays between similar chipsets, e.g. from an Intel ICH8R controller to an ICH10R controller, but not between manufacturers as you've tried.
You'll need to create a new RAID array on the new board, wiping the drives.  I'd advise backing up any data you need first, assuming you can still boot your old PC with those drives.Well that's just the problem, the new board board doesn't support RAID. and when i changed back to my old motherboard to backup data, it couldn't boot anymore. THANKS for your replies everbody. I just wiped the disks and tried to recover my data with RAID reconstructor and got around 90% back.Ah, of course, I forgot the ICH7 doesn't do RAID, sorry.
Unfortunately it can happen that way sometimes, once you try to boot off an array on a different board it can become corrupted especially with RAID 0.
Glad you got most of your data back at least.
