do you hear some clicking sounds when you plug it in?
if yes, its a piece of junk, but if not you may try to ask some store there in sofitel if you can have their external HDD enclosures tested first before you buy-with your hdd, saying if it works you pay them and give some tips, if still a no no...no chance dude!
there might be some chances of some ic's of the enclosures are damaged not the hdd, but you may check..
