Test the drive with "SeaTools for Windows": http://www.seagate.com/support/downloads/seatools/ If SeaTools says the drive has "failed" or has too many errors to test, I'm afraid the only way to rescue data from it is by sending it to a data-recovery service, and that is very expensive. You may get lucky by removing the drive and fitting it into a different enclosure if it's only the interface PCB in the enclosure which has failed. Can't find your answer ? Ask !
