Player turning on and off when trying to access it

It could possibly just not have the room to hold any more data. Try deleting some files, then adding new ones.

Uhm instructions such as like adding music and deleteing
1.To add music you have to have a Media Player and the Usb cord to connect to it. You must drag songs from the Media Player to the right side of the Media Player and then click Ready to Sync
2.To delete music go to My Computer then find the mp3 then it's common sense from there.

try to get your computer to give it a drive letter go to my computer find the device right click then format. ti shoud format
at the same format by defult.

In your player's menu, go into Settings, choose USB mode, and change it to MSC. This will cause the player to show up in Windows as if it were a flash drive, and you can add and delete music by drag and drop into the player's Music folder.

If you want to delete EVERY track off the player, then reformat the player in Windows Media Player - it's a shortcut - see my "tips and tricks" on formatting mp3 players

If there are artist, album traces, then you need to click on every subfolder under your device in Windows Media Player and delete every trace that way - tedious, but effective

-Tha Mp3 Doctor
There are 2 ways to format an mp3 player - if you were formatting the mp3 player from "My Computer," then try reformatting from Windows Media Player instead - I have a "tips and tricks" entry on How to Format an Mp3 Player for details

If that doesn't work, then double-click on My Computer, double-click on the Sansa player, and go to the various folders that it lists - music, voice, etc. Delete the songs ONLY - do not delete the dat, bat, ini, inf, or other system files

you must use windows media player 10 or 11 to sync songs into the sansa. Make sure you sync it this way or else your songs will not go in properly.

Try to reformat the card. Go to My Computer then right click the drive corresponding to your sd card and select format. Put some music back on, and try again. When your Sansa boots you should get a message stating it's refreshing the database. Good luck.

Mp3 files can be loaded using either WMP or Windows file manager (Explorer) but a different USB setting is required by each. WMP uses the MTP setting while Explorer uses MSC. If you used the wrong setting this may have caused your problem. Also for some reason MP3 files loaded using a file manager will not appear when trying to view them using WMP. To solve the issue I used the MSC setting to view all of my MP3's using file manager. I then deleted the ones I had recently added, changed the setting back to MTP and reloaded them using WMP. Worked like a charm. Hope that helps.
