    Re: external hard drive can not be detected by my pc

    do you still have a windows computer around?
    if yes:
    -plug the drive in there
    -does it work ok there?
    -sign off the drive with "safely remove device" from the system tray (near the clock)
    -when windows says it's safe to remove, unplug the drive.
    -now plug into ubuntu pc
    -does it work now?
    It's a GIANT MUSHROOM... MAYBE IT'S FRIENDLY!
