Question about SanDisk Sansa e250 MP3 Player

Sansa e250 keeps connecting then unconnecting on computer USB

Hi, My new Sansa e250 plugged into my computer just fine the first day (via USB connection) and I was able to download many songs. Then I played it for a bit on my car radio (with FM transmitter) on the way in to work on the next day (worked fine), and tried to plug it into my computer to download more songs. Now it won't stay connected. It will light up, say "Connected", and the computer will acknowledge it. But about 30 seconds later, the "connected screen will fade and it will switch to "music" mode as if it weren't connected and the computer doesn't see it. Then it will re-connect and repeat the same thing. It will continue to do this over and over. What is wrong and how can I fix this? Nothing tramatic happened to the player that I'm aware of. Thanks, EC

I found a solution (by calling SanDisk, duh). They said that the computer was perceiving the mp3 player as an mp3 player, which requires more power (and thus causing it to shut off, for some reason). They had me scroll to the settings page on the MP3 player (settings > USB ) and choose "MSC" (it was in "MTB" mode). In MSC mode, then the computer perceives the player as just another hard drive, like a memory stick, which requires less power. Sure enough, the player stayed connected, and I was able to download all my songs.

They also recommended that I plug the player into the back USB port of the computer, which connects directly to the motherboard, rather than the front USB port. The back ones are at full 2.0 power, while front ones may be at a lesser power.

Ciao

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.

HI, MY NAME IS ANGELA. I PURCHSED A SANSA MODEL

The Sansa charges via the USB cable. Fully charged, it should be good for 12-15 hours of playing. Be aware that not all computer USB ports put out enough current to charge external devices. If your computer doesn't charge the Sansa, try a different computer. You can also charge the Sansa using other USB charges, such as you'll see for charging cell phones from a wall outlet or a car cigarette lighter.

Sansa icon will not appear in source window

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.

My sansa e250 mp3 player is unable to connect to computer nor recognized to use .It won`t turn on change the modes

turning on to change modes is your problem. If it's completely dead you may need to replace it or refurbish it. Or if the battery is completely dead plug it in all day until you can get it to turn on. ONCE ON then you can worry about getting it to connect. Try this:

Couldn´t connect SanDisk Sansa e250 to Computer

I don't know what to tell you, but since nobody else is helping. Make sure that you've got the mp3 player plugged into a usb port.

Oh, and hopefully you're running XP or Vista. Sandisk requires it.

Sansa e250 - Won't power up unless connected via USB

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.
