This was an interesting one:- As soon as I started to disassemble the western digital hard drive backup, I could detect a burnt odour about it. Once open I could clearly see the Sata power socket had melted onto the drive itself.
The drive was extracted from the casing, and the power plug on the drive was repaired so as to power the drive up.
The drive refused to power up and a faint clicking could be heard. Once I checked into it further I could see that the RF shielding that was factory installed was shorting the drives motor out.
With the Drives RF shielding removed the drive spun up and all data was recovered
