2. Then I will try again to reboot it and check again within the BIOS (if it will not work or the
user tried to install a new hard drive when it happened, I will look at the SCSI termination if
this is a SCSI HD. If it is a EIDE, I will look at the jumpers settings of the EIDE drives because
some HD will not work with the jumper sets as primary with other drives on the same channel
[primary or secondary] so the jumper should go out). Then again I will reboot the machine and
if it will not work or be recognized inside the BIOS, my last resort will be to take out the drive
plant it in a different machine and see if the 2nd machine will work with it.

Hello, here's my suggestion:
1. Diagnose if the fault is in the drive or in the machine by plugging the drive to another
computer
(preferably identical). If you don't have one, go to a computer store and ask them to try it out.
2. If the fault is in the drive, try changing the controller to identical one (from an identical
disk)-—that is
sometimes possible, sometimes no-t—be careful in this step. With controller, I mean the
controller in the
bottom of the drive, not the computer's.
3. If that didn't help, plug the drive to a computer which recognizes the parameters of the
drive correctly
and try a disk reviving tool like Norton Disk doctor (if your partitions are format that it
understands) or
some other that understands your partition format.
4. If the partitions do not exist anymore, at least not visibly to the computer and nothing else
helps, it's best to send your drive to a company that restores your data—if it's important
enough. Because this kind of restoring costs a lot.

The data cable connected to your hard disk is not functioning properly, or your hard disk has
crashed. The only circumstance when the computer cannot detect your hdd from the bios setup
very directly means hdd failure or data cable failure.

If the PC can't detect the hard disk type from the setup, then we definitely have a hardware
problem. Any of the following may solve the problem.
1. Open the case and check that the power and controller cables are connected properly.
2. Try a working hard disk to test that the controller, cable, and power are okay.
3. If you have a similar working hard disk, try changing the PCB (IDE board) on the back of the
hard disk with working one.
