If checking the cables to the hard disk (a small one for power from the power supply and a large one for data from the motherboard) doesn't help, all you can do is buy a new hard disk and go through the whole fdisk/format/reinstall_windows/windows_update/reinstall_applications/restore_data routine.
im running a win 98 system w/ a intel p1.
i was moving wires under the comp and unpluged the power. now when i start the comp, it looks for the HD but says "Primary Hard Disk Fail"
can anyone help???
