Sansa c250

I accidentaly try to format it becuase I dragged files into the wrong spot.  I didnt realize I was killing it.  Is there any way to recover this.  It powers on but there is no display and does not show up in the device management or my computer. I have tried just about everything. So I just wanted to see if anyone has some kind of solution.

thanks for your help

You might try resetting it and/or posting in the Sansa c200 series board.
