i just got this lil thing for christmas and when i tried to put some music on it/charge it,the computer doesnt recognize it at all.any advice?
Im in the same boat. Some things you can try. Try plugging into a different USB. There is a MTP protocal something download from microsoft- it didnt help me maybe you.
Luckily I have windows xp machine connects just fine. VISTA is ■■■■, but Sansa knew there were compatibility issues, Should disclose this upfront at least the on website FAQ. Very disappointing.
Personally, I don’t blame SanDisk for not disclosing Microsoft’s compatibility issues… but that’s just me. 
On XP, make sure you meet the minimum requirements as stated on the package - Service Pack 1 and Windows Media Player 10 (Service Pack 2 and Windows Media Player 11 are even better.) Vista is supposed to work out of the box with any modern MP3 player, but now there’re two hotfixes you may need; one affects all Plug and Play devices, the other affects all MTP devices:

http://support.microsoft.com/kb/939211
IIRC, their respective issues will be fixed in Vista SP1. The former issue (plug and play devices) hits me almost every time I plug a flash drive into a Vista machine, regardless of the make and model… personally I don’t think the update can come too soon.
ok thanks a lot.ill try these and report back once i remeber to
