Q: Does your disk not appear at all?
A: Proceed to physical troubleshooting topics above.
Q: Is your drive listed next to an unusual icon?
A: Windows Device Manager can usually provide information about failures in accessories. It does not display
the exact cause, or a solution, but it can assist in troubleshooting most problems.
A problematic device can be found by its unusual icon. Instead of the normal icon based on the type of device, it
is instead an exclamation point, question mark, or an X.
Right-click this icon, then choose Properties. The General tab will show why the device is not working.
Still not working? There may be a hardware defect or other problem. Time to contact
