M250 sansa 2 gig

try formatting it or updating the firmware

Try this solution:

Hook up your mp3 player to your computer
Go to your desktop and double left click on "My Computer"
When it opens you will see listing that says "Devices with Removal Storage" your mp3 player should be listed there.
Right click on your mp3 player, and a window will open, right click on "Open" and now your files/songs should be visible.
Hold the left click down and drag it across all the files/songs that you do not want this will highlight the files/songs you do not want, release, right click and then click on "Delete"
Now you mp3 player should be clear of the files/songs you do not want.
Good Luck,
I hope this helps

When transfering the songs from computer to player. First, sync device before transfering. Only do this the very first time. If you try to sync with songs already on the player, they will be erased.

To test the device. Open your comuters music file folder, keep folder open, than go to start menu, go to my computer and open the folder (D: or F: folder) It will have your player listed there.

Now with both folders open, take a song from the music folder, drag it to the sansa folder and drop it in there. It should be added to player.

I had a similar problem.
This is how I fixed Sansa m250 2GB
I have Windows XP, so if you have a different version of Windows you might have to do something else.
Connect the player to your computer.
From My Computer open the drive that says SANSA M250
If there is no folder called "audio" make a folder named that. (this is where your future mp3 files will be stored).
My audio folder was missing, so I had to do this.
Now go back to My Computer right click on the SANSA M250 drive scroll down the menu and open the folder that says "Open As Portable Media Device".
Now click on the icon that says "SANSA M250"
Now open the folder that says "FOUND.000".
If you are having the same problem that I did all your old mp3 files will show up with a file extension .CHK instead of mp3 and the names will be numbers. You can either erase all these & reload all your songs into the "audio" folder I mentioned previously or you can rename each file extension to a .MP3 instead of .CHK. (after you change them to .MP3 they will load on your mp3 player. But, remember if you do choose to rename them instead of erasing and reloading, when you want to permanently delete them you will have to access the "FOUND.000" folder again to do that.

First you need to set your Sansa m250 mp3 player to MTP mode:

) Tap your menu button and select "Settings" > "USB".
2) On this screen, make sure that there is a check next to "Auto Detect" and NOT "MSC".

Note: Music that was transferred to the player in "MSC" (Mass Storage Class) mode will not be accessible once the player is put into MTP mode.

However, the music can still be accessed by switching the player back to MSC mode.


To transfer a playlist using Windows Media Player version 10:

- Make sure device is showing as an "audio device" and in MTP mode
- Create a playlist by right clicking a song in the library, add to>additional playlists>new or by saving a now playing list
- Select the Sync tab and click "Sync settings"
- Check "Synchronize device automatically"
- Set "View" to "All Playlists"
- Place a check next to the playlists they want to transfer to device
- Media Player should then sync those lists once you hit OK.
Once you Sync for the first time a new folder "Playlists" will appear in your m250 using Windows Explorer. Once that folder is created you can even use Windows Explorer alone to create playlists, all you have to do is right click on a song and choose create a playlist. Double click on playlist > Reference Tab, on the window you simply drag and drop your songs.

Hope this helps

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)

This may or may not help you, but I've connected my Sansa m250 to two computers. One has Windows XP and the other has Windows 2000. And neither can see the other's files. The file structure you describe sounds like what I see on the Windows 2000. For some reason it shows it as a disk - the same as a memory stick. It can't see what was drag and dropped or loaded by Windows Media Player. So I would make sure I used the same computer that was to used to transfer the files.

the card shows up as a separate drive letter, remember that
when the card is in the player, look for the second drive letter in My Computer and add the songs to it not the first; yes the card will show up in your library on the player only after you have unplugged it and restarted the player.

Gagan, Please see my answer here http://www.fixya.com/support/t149468-san_disk Formatting your Sansa should do it. Let me know if it didn't and please rank my answer. Thanks, D.
