The very first thing you should do is to look for signs of damage. To do this, power down the computer or external hard drive. Remove the hard drive from the computer and examine it for “hot spots” on the external controller board. You should also look for any broken parts or other signs of excessive wear and tear.


If there are no obvious signs of damage, you’ll need to carry out some checks. The best one to do involves plugging the hard drive in with new cables. Using brand new data and power cables will show you if the hardware or the peripherals were faulty.


To check if the motherboard is at fault rather than the hard drive, connect the hard disk to another PC. Powering it could show you where the fault lies.

Hit it

Putting a hard drive on ice or squeezing it are some of the more extreme methods people us to get their drive working and hitting it is another. If the drive is recognised as a USB device but it doesn't appear as a drive letter, it’s possible that the head has got stuck. If that’s the case, give it a hard hit on the narrow edge near the cable connector end as this should free it up.

Freeze it

This method’s only ever going to help you if the hard drive’s overheating. If that’s the fault your device has developed, perhaps the centre shaft has over expanded and become stuck to the bearings. Freezing the drive in resealable plastic bag for 2 hours will sort that issue out.
