Sansa is not working

Did you try plugging in a different set of headphones? If other headphones work, maybe you need new headphones.

Try playing music from your Sansa through the computer, while it is tethered. If you can do this, it may mean that the audio amplifier part of the Sansa is broken-- Usually this means, 'get another Sansa.'

Also, try gently wiggling the headphone plug to the left and right, while it is plugged in. If you get music on and off, its possible that the headphone connector on your Sansa has a broken connection. This is a VERY difficult problem to fix (without breaking or melting something else inside the case) and also usually means it is time to get another MP3 player.

Your SanDisk Sansa Player does not allow you to delete files from within the player. Deleting Music Files On Your Sansa MP3 Player When your player is connected to your computer with the USB connector, you can use your computer file browser software to view all files on your player. Your player will appear as Sansa m230 or m240. Follow these steps: Playing Music 1. Use the USB connector cable provided with your player to connect the USB port on the top of your player to an open USB port on your computer. The player will appear as a Windows Portable Device on your computer. (Can’t find the USB port on your player? See The Basic Controls section on Page 3.) 2. Delete your music files to the player with software tools like Rhapsody, Windows Media Player or Napster Client. 3. To use the Windows Media Player, Rhapsody Client or Napster Client software to delete files to your player please refer to the Windows Media Player, Rhapsody Client or Napster Client help file. NOTE: While you can store and organize your audio files on your player using folders with names you select, your player will ignore folders and names. Instead, your Sansa player will extract information from each audio file so that you can use the software menu to navigate your files by artist, album title, song title, and other useful criteria.

Open your sansa clip from its icon (might show up as removeable drive)
in the My computer section of explorer
dbl click it, this should open it up in explore, then just drag stuff to it

you may be adding to exsternal memory

copy the music's that you want then paste in the window with the files.(the music that you want to copy to the mp3 must be at mp3 format , if the music is not on that format use this converter http://superdownloads.uol.com.br/download/100/free-wma-to-mp3-converter/ )
please rated my solution...

I experienced a similar problem caused by corrupt files saved on the internal memory of my e280.
(I could not delete/remove the files) I had to format the internal drive of the e280
and re-copy the files back on to the unit. Works great now. When formatting the device
use the command from windows. (ie right click on the internal memory icon and select format)

Note: Formatting will remove/delete all the files (eg music,photos..) from the e280 so make sure that
you have backups.

Cheers

please send a driver of scandisk sansa m240

Sansa c200 series – Computer/OS Not Recognizing
Connect the device to the PC in MSC Mode
View/c200: Turn on then press and hold the rewind button while plugging to the PC
If that fails, unplug the Sansa from the computer. Uninstall all the Sansa software in the add/remove programs section of Control Panel. Reinstall the clean version of the software from Sandisk’s website – make sure you get the files for the c200 series. Then replug the Sansa and try again. The root of the problem is that Sansa has one set of drivers and Windows has another. If you plug the mp3 player into the computer before installing the Sansa drivers, the Windows drivers will trump the Sansa’s.
Here is a helpful link from Sandisk on the problem with extra information on Vista operating systems:

First turn on the palyer and change the usb mode to MSC and when you connect it the the computer it should show up as a flashdrive type thing. right click on ita and select format make sure the when you format it it is going to be formatted to FAT32 type it will delete every thing on the player including those files you said couldnt be deleted

'Refresh Database' doesn't mean everything is erased. It only means it's writing the progress that you made, onto the computer. It stays on 'Refresh Database' for about maybe 5-10 minutes. It refreshes its database every time you disconnect your MP3 player from the computer. What it does when you disconnect it from the computer is it saves any unsaved changes made to it and overwrites the memory or data.
