Major damage on my sansa e260

You should make recovery mode on your player then make firmware upgrade.
The recovery mode:
1. On your Sansa player, press and hold the Power/Menu button for 15 seconds to turn the device completely off.
2. Slide the Hold switch so the orange portion shows.
3. On your PC, double-click My Computer
4. On your Sansa player, press and hold the REC button while connecting it to the PC.
5. Release the REC button when a 16MB-FORMAT drive partition appears under My Computer.

Either your earbuds are damaged or the headphone jack was damaged when you were working out or storing your player.

Your best bet is the warranty, or if you're skilled enough, a good set of miniature screwdrivers and a soldering iron. Also be sure to have some kind of dry cleaning solvent or some isopropyl alcohol and somekind of applicator to clean with.

Open up your player( 4 screws on your backp[late, and 4 more at the corners once you're inside). Once you have everything unscrewed, gently, pry apart the inner workings from the front plate, and then the rear cover.

Now you should be able to look at the headphone jack and notice two solder points attaching it to the ckt card at either side. inspect either point for corrosion or damage and repair as necessary. While you're at it, go ahead clean out anything else that needs cleaning and before you put everything else back together.

Remember when cleaning to be patient and smooth, as any kind of rushing may damage the inner workings of your player.

Menu - Settings --> Reset All
This option will reset all the Sansa e200 player’s settings back to
factory defaults.

You should be able to access it as a flash drive straightaway; yes, the Sansa.com site has drivers on it.... But keep searching the web on

...and try changing the Sansa between USB modes.

To reformat:
There are two ways to format an Mp3 player - one on the computer itself, and one in Windows Media Player. Both methods will end up erasing all the songs on the player, but the player will be "good as new" after that. Sometimes reformatting in this manner will override the player's native formatting and cause problems - this can be reversed in most cases by updating the player's firmware. Firmware upgrades are available from most manufacturers' websites.

WARNING: The following procedures will erase all songs on the player.

Check if the file system is NTFS. If yes, format it to FAT or FAT32. - Connect player to computer, double-click my computer, right click on icon of mp3 player and select format. This only applies to Windows-based computers.
You can also format the player in Windows Media Player itself:
Connect your Mp3 player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "name of Mp3 player here 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.

Download the Sansa Recovery Tool from the Sansa website.
Format - Erases Everything: Connect your Sansa player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "Sansa 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
Firmware Upgrade- Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once. Note: this method doesn't work if already have the latest firmware. Go to this website and click "Firmware Updater" to find out: http://www.sandisk.com/Retail/DriverDownloads.aspx
