The only thing left is the USB cable and the conversion circuitry between it and the drive connector. Listen to the drive. If it clicks a lot it isn't getting enough power from the USB port on the PC anymore. If it's OK, then it's back to the cable or the conversion circuit.

take the hard drive to a computer repair shop but from your description , it may be dead
if it is a disc type hard drive , then continually moving it around is not good for the delicate workings
if it is dead , replace it with a solid state hard drive which has no moving parts and is a lot more robust

Sounds like a disk error and it cant read the start of the drive. If it still detects it you might be able to repair it with a partition recovery or partition repair tool available online.

Problem may simply be with USB cable used. Try another cable, preferably a known good cable.
Problem may be with the socket on the device itself where the USB cable fits in. Try (with known good cable) on a flat surface with the both the device and the cable resting on the surface - i.e cable should not hang down and put weight on the socket.
Hope that fixes it.
Further advice. Even if problem seems fixed, immediately back up the drive if you can!

It doesn't require a power supply You may need to install a mass storage driver. What operating system are you using? Vista? XP? Win7? Win8? 32 bit? 64 bit? Was the drive used on a Mac? Are you on a PC right now with it?

Yes, but there are many recovery software that you can download from the internet.... so don't worry, try 4shared.com by searching Recover My Files which is very effective. Please note to format your HDD using Quick Format rather than Full Format.. Good luck..

try other usb port, or other computer and see whether the hdd is detected. If still not, try to go to device manager ( http://www.computerhope.com/issues/ch000833.htm ), and then assign a drive letter to the hdd. After that, try to access it from Computer, if not able to access it, format it (use quick format) and then use this program to recover your files.
