The different parts of a hard drive that can be damaged

The Firmware

Check if your drive is a Seagate 7200.11 or 7200.12 . They are well known to have firmware issues. A “simple” firmware issue could appear like a mechanical failure with a proper clicking sound of the drive’s head stack.

The Printed Circuit Board (PCB)

A PCB (printed circuit board) is easy to unscrew. Check if you see some damaged or burnt chips this will give you an indication.
Swapping a hard drive PCB needs a bit of knowledge, but doable.

The heads

If one or several heads are dead, then it is recommended to use a clean room class 100 ISO5 to open the drive and swap the head stack.

The Engine

This operation need a special tool (expensive too) and some expert to handle it. Don’t try it yourself.

The Magnetic Platters

The worst case is when the platters are scratched, which can happen when a hard disk is dropped on the floor. In most cases, when platters are scratched, the recovery is partial or impossible.

External casing or cables

If this is an external hard drive. It could simply be the cable or the usb casing that has an issue. Try changing the cable. Open the enclosure get the drive out and plug it on a motherboard to see if that works.
