Ok heres the deal. I'm running IRC(might have gotten a virus), and I'm away from my computer for about 3 hours, when I come back, its frozen, I mean, its either frozen or crazy slow, so after I try some stuff out, I hit the restart button on my computer. When I do, it goes through the BIOS all fine, but when it goes to load windows, nothing happens. Well, this sort of thing had happened a few times(maybe a bad hard drive?-I think its those damn connectors) before, and all I had to do was run chkdsk. However, when I go to run it this time, it wont. It doesnt even ask for my admin password, like it usually does. It recognizes the drive and all, but it gives me an error. I ran Partition Magic, and it found it as well, told me it was full, and that there was a bad signature or something like that. Well, it shouldn't be full, so I don't know what happened. If anybody knows what to do, please help!! I'm prolly going 2 bring it over to the computer shop around here, see if they can't do anything.

Heres my setup:
2x 80 Maxtor SATA Raid0
Controller: Silicon Image 3112r embedded in my Gigabyte 8KNXP.

Thanks for all of your help!

Stuff you can do. Check drives are physically connexted and both operational. Remove the drives, reboot computer, power off, reattach drives. Go into RAID setup and check both drives are recognized in RAID setup. If you have Active Partition Recovery delete the RAID array and build it up again with the exact same settings as before and use APR to recover the partition.

What I do if a drive goes down from my array is connect it directly to a port on the motherboard and run a manufacturer's drive diagnostic on it to see if it reports problems. Windows won't be able to recognize the partition or data, but a boot diagnostic should be able to do a surface scan and see if bad sectors are involved.

I've also heard something about "disabling an accoustic bit" on the drive if it's in RAID. I'm not sure exactly what this means because I use Maxtors and those weren't on their list, but I think it was the 3ware site and they said that a drive will sometimes time-out on an array because of whatever this accoustic bit controls, and will just jump off the array and bring it down / send it to degraded mode.

It's also a good idea to boot your OS off of a single drive and connect a raid-0 as a secondary drive, that way you have access to the controller's graphical tools inside windows, which can give you more control and information. Your system will boot slower, but you will be able to install all your programs games and swapfile to the raid drive so they will still get the speed improvement.
