I have had my Western Digital external hard drive for over a year now and everything has been fine. That is, until last night when I went to access it. The computer kept locking up. I thought a reboot might fix it, but that didn't help. It shows up in the device manager but not in the my computer window. I've also tried plugging it into different usb ports just in case the computer was being a pain about which one it was in. Even tried uninstalling/reinstalling it several times. Still nothing. It shows up in the safely remove hardware, too. I thought maybe a windows update caused the problem, but I did couple of different system restores and that didn't fix it either. Any ideas as to what could be going on?
