There are be a number of possible reasons:

1. Electrical failure due to a device going bad or

2. A short circuit on the printed circuit board causing PCB and or component damage

3. Drive's motor gone bad

4. Read/Write head crashed due to mechanical shock

5. Firmware of one or more chips on the PCB got courrupted Before concluding that the harddisk is bad you can also check if the jumper settings are correct, power supply voltage coming to disk are correct, the motherboard is correct and the cable connecting motherboard and harddisk is correct. - Neeraj Sharma
