How do I know my device
is in USB mass storage
mode?
When your device is in USB mass storage mode, a picture of a device connected
to a computer is shown on the device screen. Also, you should see two new
removable disk drives listed in My Computer.
The device is connected
to the computer, but it will
not go into mass storage
mode.

Disconnect the USB cable from your computer.
2
Turn off the device.
3
Plug the USB cable into a USB port on your computer and into your device.
The device automatically turns on and goes into USB mass storage mode.

Verify your device is connected to a USB port and not a USB hub.
I cannot see any new
removable drives in my list
of drives.
