  108. Hi its me again.
  109.  
  110. Thank you very much for your help on Sunday. It really worked. However, I ran into problems again. I tried to sync the Sandisk sansa c250 with a Windows Media player and after rebooting it starting acting weird and it said there were no songs in it. the empty space in settings in the player display showed some enormous number in MB.
  111.  
  112. Today, it is acting even worse. It shows the boot screen and then that's it.
  113.  
  114. Recovery mode seems to be working because when I lock the "hold" switch, hold the record button, and press the power button, the boot image comes up (which says Sansa and shows the picture of a reptile) and there is a prompt that says "Please connect USB". So then, I turn the lock "hold" switch to the white part to turn hold off and then i connect it to the USB with the computer. Then the prompt says
  115.  
  116. Mini-B->Device Mode
  117. USB2.0 MSD
  118. LUN0 locked
  119.  
  120. When I open disk utility on the computer (Mac OS X, 10.4.11), it shows up the 16 MB unformatted partition, detailed information is as follows:
  121.  
  122.
