First of all, never buy USB external hard drive. It is cheaper because they use 2nd rate drive or returned bad drive to make them.  Sound like the drive motor is gone, don't think there are much you can do about it. You can try the following but most likely it will not work: Put the drive in a water proof zip lock bag and squeeze out as much air as possible. Put the drive in freezer for an few hours, then hook it up to the computer (make sure the drive is DRY).
The lower temperature may allow the drive to spin up again for a VERY short period of time. Copy out all the data you need as quick as possible.
