Combining parts from two computers since I picked up a laptop. Took a 120GB WD HDD out of one desktop running XP and added it into another running XP. Drive shows up in device manager, and it says it is working fine, but it doesn't show up in my computer. Both drives are set to CS, and MB is Asus A7N8X. They are on the same IDE cable, and I just can't get access to the drive even though it appears in the system and in the Bios it autodetects and seems fine. What am I doing wrong?
