If you have a v2 model, you can use the following instructions to ‘force’ MSC mode.
To force the c200v2 in to MSC mode:
- Make sure the player is off (if necessary, hold down the power button for 20 seconds to turn it off)
- Move the hold switch to ON (move to the right towards the record button).
- Hold the rewind button (Left Key)
- Connect the player to the computer.
- Keep holding the rewind button till the “Sansa C200 (E)*” comes up, then realease the record button. If the removable disk does not automatically launch, open “My Computer” and check for any additional drives.
- Now you should have a Sansa C200 with a drive letter assigned to it.
