'''Arun Ahuja''' ditch the enclosure. Get a Zif-to-USB adapter, something [https://www.ebay.com/itm/Computer-PC-USB-CONVERT-BOARD-CABLE-ADAPTER-1-8-CE-ZIF-PATA-MK2008GAL-MK3008GAL-/253877151612?_trksid=p2385738.m4383.l4275.c10|like this] so your computer can recognize your HDD (also both must have been the same OS i.e. Windows or Mac. You can not mix) Male sure that you get an adapter that has the right ribbon cable. Toshibas and Hitachi use different cables. Apple uses a weird structure for the way files are saved on the HDD. I use CopyTrans to backup the files. There are multiple other pieces of software for this task that work just as efficient.
