I'm having some problems with my Transcend StoreJet external hard drive. I had it for a while now and it was working normally until now. At first, it seemed to be fine but when I clicked on it on My Computer it asked me to format the drive. I thought that was strange so I unplugged it and re-plugged it back in. But it now doesn't even show up on My Computer anymore. I checked on Device Manager and it's there. I tried re-installing the driver but that didn't help. Please help me. I have important files on the hard drive.
