Can't see mp3 files in Windows 7!

If you have a v2 model, you can use the following instructions to ‘force’ MSC mode.

To force the c200v2 in to MSC mode:

  1. Make sure the player is off (if necessary, hold down the power button for 20 seconds to turn it off)
  2. Move the hold switch to ON (move to the right towards the record button).
  3. Hold the rewind button (Left Key)
  4. Connect the player to the computer.
  5. 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.
  6.  Now you should have a Sansa C200 with a drive letter assigned to it.
