continuous beep
A hard drive has overheated. Check if the fan on the back
side is running.
If the fan is not running, turn off the DriveStation Duo

still does not run after removing dust, it may be broken.

If it is running, the hard drive may have failed. Check the

still may have overheated even if no access LED for either
hard drive is lit red. Turn off the power, and wait at least
one hour before using again.
