Question about SanDisk Sansa m250 MP3 Player

HELP! my sanza m250 can't see the song files even though the songs can be played on the player

Hi, I have just had a new m250 one month ago, I copy the mp3 song files from my computer to my mp3. The songs work just fine on the player, but when I connect to the computer, there is no song files. I want to copy the song for my friends and also want to delete some songs, but there is no files when it was attached to the computer. I can't do anything. I tried to change to MSC and auto for the USB format, but it still does not show any music files. (When I change to "auto," the computer does not recognize the sanza, but when I change to MSC, the computer recognize it, but no sound files anywhere, even in the audible files, it's empty). I also tried to reformat the device, but it says that "I do not have sufficient rights to perform this operation." What should I do? Please help me!!!!

    I Have a similar problem. My sandisk has wma files on but I cannot see them on windows on my computer. I need to delete these to add more...I can see them on my player menu but following the delete instructions it doesn't delete them. I added some Madonna mp3s which show ok on computer and player and which I can delete from computer but not the player.

    This problem is posted multiple times on FixYa, and I haven't seen a real soltion yet. For the second time,

    I have the same problem, and the proposed solution doesn't work. To clarify, there can be audio files on the device that are invisible to Widows Explorer and WMP (I am using XP), although they are still there when you use the player. These are visible in plaintext in the file MTABLE.SYS but if you edit it with, say, Notepad, the device rebuilds the MTABLE.SYS file with all the files you would like to delete. If you check the properties of the MUSIC folder only the visible files show up, and deleting that folder along with RECORD and AUDIBLE does no good whatsoever. Probably related is the fact that in WMP the Sync view "Sansa m250" device reports sucessful "Sync Results" but "Artist","Album","Songs", etc all declare "there are no files on this device" even when you've just synced non-invisible (deletable) files to the device. Apparently the device has a proprietary file system and is faking, unsucessfully, its responses to the applicable system calls. Or somesuch screwup.

    Mine worked perfectly fine, I could see, add, and remove the files from the player while it was attached to my computer UNTIL I installed IE7. Now the player is being recognized as file storage only when I connect it to my computer and it shows NO FILES on it. I am so frustrated I am ready to pitch it.

    I have had my mp3 plaer for about a year almost two and it's just now showing it as removable device. And I'm not able to see my other music files that I have allready on my mp3 player.

On the MP3 player, go to Settings> USB. If Autodetect is selected, select MSC (only one or the other can be selected).

Rock 'n' roll! I switched mine FROM MSC to the other choice (sorry, it's plugged in right now and I don't want to jinx it by unplugging it and seeing what the other choice it) and it worked!!! I just opened it in WMP and there's all my long-lost music. So I guess try both. Thanks for the help -- even if it was indirect, I would never have figured this out myself.

Here are few things to check with to get your device working....
1. Check the version of Windows Media Player you have. Open Windows Media Player - Go to Help and choose: About WMP and that should tell you the version. 2. Upgrade WMP to v11 from this link:  3. If you have both and if your device is still detected as a Removable Disk, follow these instructions:
i. Connect your Device
ii. Right click on My Computer and select Manage
iii. Select Device Manager
iv. At the right hand side look out for Portable devices and click on the + symbol to display your device
v. Right Click on the device and select Update Drivers
vi. Select 'No, not at this time' and click Next
vii. Select 'Install from a list or specific location' and then click Next
viii. Select 'Don't search, I'll choose the driver to install' and then click Next
ix. Select 'MTP Device' and then click Next. This should install the device and then should be ready for use.

If none of these solutions work, you may have to chek for any firmware update.
wish you good luck!!!

I want to confirm cindiwindi's solution. It seems to have to do with how the Sansa reports itself to Windows when it is attached to the USB port -- as a simple mass storage device or as a specifically media device. It's really dumb that SanDisk doesn't prominently and clearly document the problems caused by this confusing "feature".

Files not deleted from m250

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 playing my mp3 the songs that i have downloaded off my pc from a paid site, across the screen of the sansa says synchronize to continue your music subsription. the songs will not play please help me

Even though you should be able to resynchronize the files through Rhapsody in order to update the licenses on the music files, in my experience with this player, you have to go through a long, painful process:
1) Open Rhapsody
2) Connect your mp3 player to the computer
3) Delete the songs off the player itself using Windows Media Player - but make sure you still have a copy of these songs on your computer
4) Reload the Rhapsody songs

If your subscription to rhapsody expires, you will no longer be able to use the songs unless you buy them from the Rhapsody Mp3 Store.

Sansa m250 playlists

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

Digital mp3 player

the file you are trying to copy might not be an mp3 file. mp4 files, and i-tunes files will not open on an mp3 player, they only show up as data. quite simply, you need an audio converter.
