I posted somewhere else but here is a copy : ------
I don’t know much about computers.
The problems are greatly varied but my problem was answered by below:
Instead of entering “Recovery Mode” I was referred to a website that told me how to go into “Diagnostic Mode” .
Put “Lock ON” ;
Hold down “Down Button” and then hold down “Menu Button” both at same time . *** THIS IS DIFFERENT THAN RECOVERY MODE . *****
A bunch of options will flash through the screen .
I just released the “Menu” button and then the "Down " button for lack of anything else to do .
It showed some options I didn’t need .
But then I Pushed the 12 o’clock = “Up” button and it gave the option to Re-Format !!!
I followed instructions to Re-Format which was to push the 3 o’clock button = “Next/Forward” button to start Re-formatting .
Within a minute it was done and had brought up the Language Selection prompt !!!
I checked the settings for system info for the memory and it was right on the money !!
I made sure USB = Auto-Detect .
I turned it off and hooked up to the Computer PC and it recognized the c250 in Windows Media Center .
I transferred a playlist to test it out .
Everything works fine !
I have Windows 7 64 bit OS
Sansa c250 MP3 player .
I hope I help some people out !
