Is it recognized by your BIOS when you boot up?
Edit- If not, you're probably looking at a dead drive.

after hitting tab at start up and going into bios setup, it only lists one WD2500 HDD, so i'm guessing that's probably a no.
ok, now when i try installing steam to the HDD that is working, i get this error message "Error 1327. Invalid Drive: F\." F being the drive that my computer no longer recognizes.
