Sansa clip frozen to screen 'SanDisk sansa'

You can use the chkdsk function only in MSC mode.

You can force MSC mode by starting with the Clip OFF.  Slide the power switch to the HOLD position (orange showing).

Press and hold the center button down while plugging in to the PC.  The device will connect in MSC mode.

You may then run chkdsk on the device.
