If it's not showing up there or Disk Management (which is where I partition and format) then it's failed. Try another cable, case and then drive.
The drive doesnt show up in my computer, or in the device manager. The lights are on, which means that it should be working. Only, when I listen to it, it sounds like its trying to go, but its getting stopped. It doesnt work in my PC, or a MAC. I'm running XP, and up untill a little while ago my drive was working perfectly. And I can't format the drive because it doesn't show up in the device management. Any help would be nice.
