Measure the resistances between each pair of motor terminals.

thanks for the reply fzabkar. Sorry for being a complete noob, I can work a multimeter but where are the motor terminals? Would you be able to explain this in more detail for me.
Thanks

I agree. I think what Fzabkar is saying is that the drive likely has internal issues, possibly heads stuck to the platters.

What you do to the drive at this current stage will determine its outcome. If you value your data send it to a professional. Whatever you do, don't open the drive. It will only make it worse and more expensive.

There are 4 pins connecting the motor to the PCB. The resistance between each pair of terminals on the motor (not on the PCB) should be of the order of 1 - 2 ohms.

If the motor is OK, then you may have a stiction fault.

Ive measured the resistance across the motor terminals on the HDD with the following results
1-2 = .001
1-3 = .001
1-4 = .001
2-3 = .002
2-4 = .002
3-4 = .002
Does this mean that the motor is broken?
