You must re-format the player and re-add the songs - the DB has become corrupted.

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.

Do you know if windows media player recognized your device? if windows media player does, i would recommend you to format the device using windows media player...to format your device have it connected and open up WMP,click on the sync tab the your device will be listed on the left side..then all you have to do is right click and format the device..that should work..

Try this: disconnect the player from the computer, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.

You can format the device to remove all of the residual information. My Computer>Device Name (e250)>Right Click and select format. Best of Luck.

- As with nearly ALL sansa e250 problems, formating it will bring it back to normal. 1. Connect it to your computer. 2. Open 'My Computer' and right-click the device. 3. choose 'format...' and then 'quick format'. 4. If you haven't done so, upgrade the firmware: -Find the firmware on the Sandisk home page. Don't use the wrong one, though. If you have a Rhapsody version, choose the e200r player. Download the .zip file and extract its contents (right-click, 'extract all'). Then connect your player to your computer and drag the extracted file to your player's drive. Now when you turn your player on, it'll undergo the firmware update. You can also update your firmware by connecting to Rhapsody with your player hooked up and following the firmware update instructions when the window comes up. If the firmware update window doesn't appear, then you have the latest firmware to date. 5. Test out the player and see if this method worked. If not, you may want to send it back sandisk or return to the retailer you bought it from.

Hi. The minimum requirements of your Sansa E250 is Windows XP and above and Windows Media Player 10 and above. If you're using Windows Media Player 10 or above, your Sansa E250 and its contents should appear on the right pane when you click on the "Sync" tab. You can right click on a song and select "Remove". The songs will be erased permanently from the player. If your songs do not appear on Windows Media Player 10 or above, it is possible that your songs may have been saved on another mode. Your Sansa E250 comes in 2 modes: MTP and MSC. Songs saved on one mode will not be seen by the other mode, and vice versa. There are 2 ways to delete songs from your Sansa E250: By browsing the folders containing the songs, or by formatting the player. You can switch modes by navigating your E250's menu using the following: Menu >> Settings >> USB Mode Next, plug your player in your PC and open Windows Explorer. You should first set your Explorer to "Show hidden Files and Folders" by going to the "Tools" menu (located on menu lists on Windows Explorer window), then choosing "Folder Options", then enabling the "Show Hidden Files and Folders" radio button Deleting Music files under MTP Mode: 1. Your player should appear as a Sansa E250 icon in Explorer as a "Portable Audio Device". Double left-click this icon to browse the player. 2. You'll find a "PPI NAND" sub-folder. Again, double left-click on this sub-folder. 3. You'll find a series of sub-folders, one of which should be titled "Music". Double left-click this to open it. 4. Your music should appear as individual files or folders. Delete this to remove the file(s) from the player Deleting Music files under MTP Mode: 1. Your player should appear as a Drive letter and entitled either as a "Removable Drive" or as "Sansa E250" 2. Double left-click on this drive letter to browse the player 3. You may find your music files immediately on this folder, or you'll find a series of sub-folders, one of which should be titled "Music". Double left-click this to open it and view your music files. 4. Delete the music files you want, and they should be removed from the player Deleting files through Format: 1. Formatting the player erases all files in the player, and oftentimes this is the best option to ensure that all files are removed and any corruption eliminated. Also, it is best to format the player when in MSC mode. 2. When the appears as a drive letter (under MSC mode), right-click on that drive letter and select "Format". On the "Format" pop-up window, click "Start" to begin the format process. 3. Follow the on-screen prompts and safely remove the player from your PC when the "Format Complete" display appears. 4. Unplug the player from the PC and when the player is powered up, the message "No Files" should appear on the player's LCD screen 5. Switch the mode back to "MTP", or continue to use "MSC". Note: It is best to use "MTP" when you are transferring subscription music to the player. I hope this helps. :)
