Ok...I have Windows XP Professional, and am using a P4C800 Deluxe Asus Motherboard.
A couple weeks ago I got a really bad trojan, but I was able to remove it. I actually removed my C drive, and stuck it in another computer so I could run scans on it and whatnot because it wasn't letting me do anything with that trojan on it. I was able to remove the virus, I put the drive back in my computer. My computer has 3 hard drives, There's a C drive(150gb Raptor SATA), an F drive(160gb WD IDE) and a G/H drive(partitioned 400gb WD SATA) Since I put the C drive back in, My G/H drive disappeared, and when I booted up it gave me the Delayed Write Failed with a message referring to the G drive. It also took forever to boot up like in between the Windows logo screen and the welcome screen it just sits on that black screen for a couple of minutes.
So I went to the device manager and noticed I have a RAID controller not installed?? I have never even done anything with RAID controllers on this machine. The hard drive is plugged into the same SATA port it was, nothing changed there. This board has 2 sets of SATA ports, and I believe one is for RAID. But it keeps detecting the G/H drive as needing to be in a RAID now. I tried going to Asus's website and downloading the RAID driver for it anyways, but after it's installed it says there is an error, and I still don't have my G/H drive.
Also, if you uninstall that RAID driver, and reboot, the computer boots perfectly, but then comes up with detecting new hardware(The RAID controller) And I still don't see my G/H drive. This pretty much goes beyond my knowledge, so any help would be awesome.
