Did the Seatools indicate what problem you have?
Do we understand this is a internal SATA disk in a Desktop?
If you have not made any changes to the system, and if the BIOS does not give the correct ct information about the drive, you would just assume the hard derive has been damaged.
Now any changes, we would mean CMOS battery replacement, changes to the BIOS setup, installation of another Operating system, use of drive partition software, change of SATA drivers or change of chip set drivers. Even opening the case may cause significant changes. Without knowing it, you may have damaged or dislocated a cable.
As a troubleshooting trick, you would want to try the drive in another machine. Or, find a similar drive and try it in your machine. The motherboard SATA connector or interface may have failed. Try the other SATA port.
