If your device freezes up press the Menu button and hold for 15 seconds.
This is like a power down of the device. Once you perform the reset, the adjustments you made during last operation
will be gone.....
Go to my computer click on folder scroll to sansa and open the media folder and open each sub folder and delete manually then delete the folders Right click on your sansa then format a couple of times hope this works
