What I would recommend you to do is to make sure that your device is under MTP mode instead of do that go under menu,setting, usb and then there should the two mode listed there...then you want to plug your device in the back of your computer..not in the front..tghat is very important....once you do up your windows media on your start thee sync panel..if your device is recognize properly it will be showing there on the right side..and if its not listed properly, it will say connect a device..if thats the on your start menu right click on computer and then click on propetties, click under hardware and then device manager..your device should be showing there...check under disk drives to see if your device is showing there and if it doesnt you want to right click and hit uninstall...we dont want your device to be under disk drive ..we want it to be under windows portable device...once you uninstall it...go to and find the driver for your device..and then connecct the device on the back of your should work properly..if you are still having any problems..let me know..i would be more than happy to assist you..

Sansa m250 won't finish "finalizing update"

Ummmmm.... What are you doing exactly if your trying to download the music, Download using limewire, bearshare,
Its not going to work on Itunes most of the time so just use Limewire or bearshare. Connect the Mp3 using the Usb thing and try to put it in front of the cpu or behind either 1 of them.
After you should probably get a pop up scroll down and go to view folders or whatever and open it and put the music you want in the mp3 and when yur done beside the clock look for a Safetly USB remover or whatever and disconnect it.
I hope it works
Give me some Credit
and click the Button XD

Sansa m250 2GB file adding problems

Can't create directories directly on the m250. I've got about 1000 songs loaded (already broken into subdirectories) that take up 800 MB and the device claims that it's full. (Firmware is also updated to 4.1.08A)

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:
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.

Sansa help

Either the device is bad, the pc port is bad, or the software is faulty. Try connecting to different usb port, then a usb port on a different pc with a compatible os. If still not recognized, then there is physical damage to player.

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.

Can not remove files from sansa

Windows Media Player is a little temperamental when it comes to music on the device.

You can manually manage the music from My Computer>Device Name (m250)>MUSIC Folder.

You can drag & drop files onto the device from here, as well as, right click and delete them.

Best of Luck.

Not enough space to listen

If it''s any consolation, the same thing happened to me after I loaded about 1.6 GB (~250 MB left) of music on my Sansa m250. I tried to delete the required 8MB, but the directory structure got destroyed to the point where my computer wouldn''t recognize the device. I called their technical support and they''re having me send it back to them for a replacement! It''s not you, but the player! I don''t know if there''s anything that can be done from a consumer standpoint.
