ok, so now the SanDisk sansa m240 1GB mp3 player, when you turn it on, it freezes. I have tried to change the battery and everything and it still wont work. What is happening here? others that have had the same problem. I researched this online and found out that there was a rather large bad batch of these mp3 players shipped in December. they suggest calling sandisk tech support at 1-866-726-3475 for a replacement and getting a RMA number or going back to where you bought it and exchanging it. For tech support, call SanDisk at (866) SanDisk—(866) 726-3475—or fill out an online support request at www.sandisk.com/retail/support.asp . SanDisk offers a one-year warranty.

http://www.mobileplanet.com/f.aspx?i=130057 found a few options that worked on one of these, I have two with the same problem. First I tried this: 1.Go to the settings on the Sandisk MP3 player. 2. Go into the USB menu. 3. Tick the MSC option. Now plug the MP3 player back into your usb port and you will now be able to see the music files! That Cleared the issue one time, on one player. To delete the files, I needed to go into my mp3 itself. 1.) Go into the player, and go to the settings. 2.) Find where it says to reset the settings to default. 3.) Reset them and plug the player back into the computer. 4.) Search for the Music folder and the songs should show up. Going to try it now on the profile for that MP3 player.

I have a sandisk Sansa M240 MP3 Player, and I am having an issue with it. I first loaded just a few songs to it, and then later I loaded it up full. Before the second time it Window Media Player gave an error indicating that it did not recognized the files already loaded on there, (something like there must have been loaded from another PC). two choices, one was to leave them, the other was to delete them. I chose to delete them and it said it did, however they are actually loaded on the device still. and WMP does not recognize them at all. I have search the web over and found no solution. The music is just stuck on there! I did upload Firmware since and it did not help at all. if anyone has any suggestions, I would appreciate hearing them. see my updated entry to help you correct this problem
