MP3 players can only play music files in mp3 file format. You can download mp3 music files from the Internet to your computer and then copy them to your MP3 player using the USB cable. For your CD collection, you need to convert your CDs to mp3 music files onto your computer or download them from the Internet and then copy them to your MP3 player after you have connected the USB cable to the MP3 player and the computer.
You can do this using Windows Media player and Rip the CDs - Media Player will create a MP3 music file for each music track. Click on this link for instruction on converting music files to mp3 file format :- http://www.fixya.com/support/r5798418-creating_transferring_mp3_music_files

connect the usb device to a window os and fix the drive. it should work.
i presume you plugged out the usb without safely removing the device eh?

look buddy first u shud get rid of the shorting out on the usb connection.

then get to samsung.com and check the support page of ur product and start downloading!!

You need to update your firmware first, then the settings menu will have the option to change the USB mode.

Get the firmware updater from here, under downloads on the right side of the page.

first off get the arcsoft media converter 3, then drag and drop the videos you want to get on your mp3 player into the program, after it converts it it loads them onto your mp3 player as long as its connected, this program will also allow you to download youtube videos and put them on your mp3 player too

I have the same problem, it also will show charging after I disconnect it from PC. Anyone have any ideas?

I have the same problem. If you have a large library try letting it stay hooked up for a long time. It seems like it is taking inventory of device then it should work after a while. Sometimes this works. Sometimes I have to unplug then try again in a few minutes.

Try to fix anti virus for your pc, maybe there's some virus in your ipod that cuase problem that say no proper connection. Sometimes the usb connection of your CPU does not work properly or the settings of your OS.

(FOUND THIS SOLOUTION ON AFTERDAWN.COM) The problem is that this player have 2 standards for connecting to PC. One is MSC and other is MTP. Each one have different directories structure. If you put music when your player is connected as MSC, when you will conect as MTP you'll be not able to see the files uploaded previous. The same case is available when you write music files as MTP=> you can't see these files in MSC mode. So, set USB mode of your Sansa as MCS, power off, put hold switch to lock and connect to PC. You will see 3 directories: Audible, Records and Config (or something like that). See if your "invisible" music files are here. If they aren't connect as MTP. To connect as MTP: set USB mode to auto, shut down Sansa mp3 player, put hold switch to unlock and connect to PC. You will see only 2 directories now. Media and "something" (I can't remember now). Look for your "invisible" files and do what you want. MTP mode is for use with newer PC's. I advice you to use MCS mode all the time because is compatible with any PC (old or new). Good luck!

I had this problem a couple of times. Turned out the battery didn't have enough juice. At least that's what worked for me.
