Troubleshooting
I can see the DriveStation in Computer (PC) but I cannot access it
The drive may require formatting. Try using DiskFormatter2. Diskformatter2 and its manual are available from

I cannot see the DriveStation

computer by a USB cable. Check that both ends are correctly plugged in.
Verify that the hard drive inside the DriveStation is spinning. This can be verified by placing your hand on the side of
the case and feeling for a slight vibration.
Also, after the DriveStation has been powered on for 15 minutes or longer it will begin to get warm. If neither of the
proceeding tests verified that the hard drive is spinning, then please contact technical support for further assistance.
My backup program cannot save files to the DriveStation.
