help with quickidrive please!

Hi Everyone, I am not much of a computer person so hopefully someone will help me with the problem. On my bf's laptop, he used to store some info on the quickidrive which could be easily accessible as an E drive. Now whenever we plug it in, it makes a sound but we don't see the E drive on "my computer". I even tried it in my personal laptop too but when I plug it in, I get a" msg saying "there is a problem with the hard drive". Is there any way you can "unhide" a drive? or is this micro hard drive fried? we have a 4GB one if that makes any difference....
Thanks for the help
