On that drive, if you set the jumpers incorrectly, it shows up with
strange geometry. If that's not the problem, try formating the drive.
Other than that, early versions of the 2940uw had buggy code. You might
want to check the firmware version and upgrade the code (If it's old).

Hope this helps...
