Indeed, connect in MSC mode, where you can run chkdsk on both volumes, the µSD expansion card, and the internal memory.
Manually establish an MSC connection by starting with the device OFF, then slide the power switch to the HOLD position, with the orange flag showing. Connect while holding the center button. The Sansa Fuze will connect in MSC mode. Note that you can also hold the << button down during connection, with the same result.
Use the command chkdsk e: /f where the drive letter is the assigned letter of your Sansa. This letter will vary depending upon your installed drives, so check this first. The second drive letter assigned alphabetically to the Fuze is the expansion slot. The /f command is a toggle telling the utility to fix the errors found if possible.
Note that you can remove the µSD / µSDHC card first, then restart the Fuze, before doing ANY of this. If the corrupted files are on the card only, your Fuze will perform the Refresh Database operation without incident when the card is removed. You’ll need to run chkdsk on the card next.
If you’re uncomfortable with using the old school command prompt, you can do this as a Mouseketeer and click your way to oneness with your Fuze using Windows’ Manage function, available via a right click, and “check volume for errors” under Tools…sometimes. Windows is a moody little thing, isn’t it?
Also available is a right click under My Computer to Manage. Selecting the Sansa, you can then check the volumes for errors.
In any case, in your clicking session, don’t try to defragment a flash memory based life form, as this messes with the cool and critical wear levelling algorithm used to maximize the life of your flash memory.
