Sansadisk mtable file problem

Hello,

Switching to MSC mode and performing a content backup
When the player does not respond to the software for the media player
in MTP ( media transfer protocol ) mode you can switch the player to
MSC mode in the player as next:
1. From the Main Menu, select Settings > USB Mode.
2. Select Auto Detect, MTP or MSC.
When having no more screen view, have a hardware MSC selection:
Forcing Sansa Clip to MSC mode, enabling the USB connection mode for the computer seeing the device as a removable disk:
Sansa Clip
1. Turn device OFF.
2. Slide the Hold switch down to Lock (orange color showing).
3. Press and hold the center button while connecting the device to the PC.

Updating firmware
Next update the firmware of the player. This will clean all your files in the player ( have a backup first as told above ) and the software in the player will be updated.

How to update Sansa Clip's firmware, see:
