Not sure if this is the proper forum for this sort of question, but I really need some help.
I have a 250 GB USB external harddrive (a Western Digital MyBook) that's been working fine up until recently. For some reason, every now and then, it acts strangely. The status light blinks constantly (it should stay lit when it's inactive) and it makes a sound as though it's perpetually searching for something. I go into My Computer to see what the problem is, and then the whole system locks up. When I turn off the HD, everything returns to normal.
This has happened once before, but restarting the computer fixed the problem up, after which it worked fine. Now restarting does nothing, and I'm at wits' end. I keep a lot of work on that HD, and it's imperative that I get this thing working again.
I know next to nothing about computers, and searching for a solution on the web yields no help, so I'm wondering if some of the experts here can help me diagnose the problem. Cheers in advance for any help, and if anyone needs more details, ask and I'll try my best to oblige.
