My pc stopped seeing the hard drive. Clicking F1 and going into setup it shows the dvd - cd r/w but not the hard drive. Tried 3 other hard drives and same thing. Setup shows the cdrom on the secondary channel as the master. I changed the jumper to slave and it shows up just fine. None of the hard drives show in setup on either of the channels as slave or master and even tried the cable select jumper. Problem is, The pc just won't see anything but the cdrom, and not any hard drive. Any ideas?
