Try this steps.
1) check whether the BIOS can detect and report the disc information correctly; likes the model number, and capacity, etc.
2) if no, then the controller broad on your hard disk may be faulty and it should be replaced by vendor. If you are a advance user and get this controller board from other source, you can try to replace it by yourself but it is not recommended.
3) if yes, check whether the motor is started or not. It can be easily detected by putting your hand on the disk or listen the sound.
4) if there is no sound nor any mechanical motion, the motor part may be failed or the power (+5V or +12V) is loss. Check all sockets and connectors to hard disk, especially the DC plug to controller board, there may be dry-join or poor contact.
5) if the BIOS reports the data is correct and motor is started, it may flected by virus which changed the boot sector or FAT.
Try it and tell me your findings.

I believe your hard disk has been over-heat at some time before such that the data written on the disk plate was un-readable. My notebook disk was damaged at that reason.
