My sansa e250 keeps connecting and disconnecting from the computer. every time i plug it into the computer, it keeps saying that it's connected and disconnected to the computer. this switches repeatidly while plugged into the computer. pleeeeaaase help me!!!!!!!!

There are two connection settings in USB: MTP and MSC. For some reason MTP is the default, but it doesn't connect properly on all computers. Select MSC and plug the player in again, the computer will recognize sansa e250 but not show the driver just yet. It is installing recognition software (just basic drivers - nothing heavy) and it doesnt tell you what its doing until its complete. WAIT FOR IT. Once it is complete you will see both the sansa e250 and the removable memory slot in your "my computer" now you're good to go.

That one time happend to me. I plugged it into another port, and it worked fine.

In this case try connecting the Mp3 Player to a diffrent Slot..........
If still it does the same thing...........
Use a Brand New USB Cable that will fix the Problem,,,,,,,,,,
Thanks

I do mine through Windows Media Player
1)Plug in Sansa
2)Open up Windows Media Player and wait for the Sansa e250 icon to show up under the library. First time, might say 'What device is this' or 'Autoplay'-for autoplay,you click 'sync media files to Sansa e250 using WIndows Media Player'
3)When library shows, click 'Sync' if it is not already there.
4)Just simply click and drag the songs you want from the computer library to the list pane on the side.
5)Once your done, click 'Sart sync'

TO DELETE
1)Plug in
2)Wait for the icon under Library in WIndows Media Player
3)Go to Songs under Sansa e250
4)Right click desired songs and choose Delete. You only want to delete from Sansa e250-nothing else

you should try putting into recovery mode. to do this, connect it to your computer, then push the hold button down so the orange is showing. Next you want to hold down the record button on the side of your mp3 player, now while holding that down also press and hold the power button. in a few seconds it should go to recovery mode. if you need more information, heres a link to the forums. http://forums.sandisk.com/sansa/board?board.id=e200

Sounds like the battery may have come loose. Remove the 4 screws on the back, remove and reinsert the battery. Charge the device for a few hours. Best of Luck.

Try Formating the Sansa. 1.My Computer 2.Right click the sansa icon 3. clock Format. Let me know if this solved your problem. D.

try going to recovery mode and upgarade the firmware of the player. Recovery mode = enable hold switch press the record button and press the menu button until it shows welcome to recovery mode on the player.

I had this same problem on my sansa and tryed the previous solution with no luck. Out of frustration i email the sansa technical support. Try these steps to format the player: -Turn on the player and access MENU > SETTINGS > USB > MSC - Once the player is set to MSC mode, reconnect it to the computer and open the My Computer window. - Once you see the Sansa icon in the My Computer window, right-click it and choose FORMAT - In the Format window, choose FAT 32 and make sure that Quick Format is NOT selected, then choose START -Once the format has completed, disconnect the player from the computer to allow it to refresh. If you plan on using Windows Media Player to transfer files, return to the USB menu and set the player to MTP mode. Otherwise, leave the player in MSC mode and you can now resume transferring files. Formatting your player will deleate all files but you can putt them back on!!! Best of luck!

These are the most common methods for recovering Sandisk's Sansa Mp3 Players. I have been almost universally successful in recovering Sansa players using one or a combination of these methods. These methods do not work if you are having synchronization or music format issues - they are for recovering a player that will not power up, freezes, flashes, is not recognized by the computer, and a host of other issues.

Reset the Sansa Player first. On most models, restart is done by holding the power button in for 15 seconds or longer. Check your specific manual to be sure. The manuals are available from the Sansa website if they have been misplaced.
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/DriverDownload/driverList.asp
If these fail, then:
Try this: disconnect the player from the computer, turn it off, 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.
If you get the problem where MTP Device keeps popping up continuously, uninstall the “MTP Device” by going to Start à Control Panel àSystem à Hardware à Device Manager (you computer may vary slightly, depending on Windows Version).
You may have to restart your computer after each of these methods to get them to work properly. Disconnect your Sansa player BEFORE shutting down your computer.
