Used for years. Deleted mp3 files. Tried to reload new mp3 files by select all and drag and drop to audible folder. Message said it was full and would only load partial. Deleted partial load safely removed. Inserted SanDisk sansa M240 into USB port and the computer never recognized the drive. The M240 screen when plugged in read initializing but never goes any further. I can plug in other USB devices, no problem.

When your MP3 Player is connected to a computer, you may transfer music files to your MP3 player using your operating system's basic file management commands (i.e., copy-and-paste or drag-and-drop).Connect the Coby MP3 player to your computer through its USB adapter. Select "Open folder to view files" from the new device dialog box that pops up. If the new device dialog does not appear upon the hardware's connection, click "Start," click "My Computer" and right-click the Coby MP3 player's device icon in Windows Explorer .Click "Start," click "My Music" and open the folder containing the music you wish to transfer onto the Coby MP3 player. Drag and drop the music files or folders into the Coby MP3 player's open directory. Alternatively, you can highlight the music files or folders and click the "Copy the selected" link from the Files and Folders Tasks menu in the left column. Select the "Removable Disk" drive from the list of destinations.

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 I had the same accident this is what worked for me. I disconnected my sandisk player from my computer. After waiting until the sandisk software completed it's termination programming, I re-connected it to the computer.

Because I use Microsoft Windows XP, a window pops up asking if I want to open the device in Windows Explorer. Answering "yes" and then selecting the "Folders" from the tabs at the top of the window will display the sandisk along the left column as "Sansa e250". By double clicking on the folder labeled "PPI NAND" a drop down list of subdirectory folders should be displayed. If the folder "MUSIC" is not there, you will need to create a new folder and label it "MUSIC".

Here is how to create a new folder.
With the folder "PPI NAND" highlighted, move the cursor up to the upper right hand corner of the "Windows Explorer" window and select the tab "File". From the drop down menu select " New Folder ". This should cause a folder to appear in the window to the right of the "Sansa e250" window. The new folder should be highlighted and labeled "New Folder". Select the "New Folder" and rename it "MUSIC". When renamed, select the PPI NAND folder and the new folder "Music" should be listed as one of the folder in the subdirectory. If so, you can select it to see if the Music folder contains and music files. If not, you will need to copy or drag your files into the new "MUSIC' folder.

Once I did all of this and disconnected my sandisk player, the player and let the software complete the programming work before shutting it off, it worked fine. My original problem was caused by shutting my sandisk player off after disconnecting it from the computer before the sandisk software completed its work.

Hope this helps.

I had the same problem two days ago.

Working on the assumption that the problem was a corrupted file, here's how I fixed it. As you'll see, I connected my Clip an Macintosh computer to fix it, but there is probably an analogous procedure using a PC. But I'm not very PC savvy, so someone else will have to figure that out.
Also, I don't know that all the following steps are needed, for example, trashing the old content folders and creating new ones, but this is what I did, and success resulted:

Connect Clip to Mac

Click on Clip's icon to open it.

Open up all content folders and drag songs, audiobooks, podcasts, etc. to trash and empty trash. (The idea is to get rid of the corrupt file, wherever it is.)

Drag all Clip system files to a new folder on the Mac desktop to copy them. This will include DID.bin, RES_INFO.SYS, SYS_CONF.SYS, version.sdk and WMPInfo.xml (Basically, I copied everything that wasn't a content folder.)

Don't bother copying content folders AUDIBLE, AUDIOBOOKS, MUSIC, PODCASTS and RECORD. (Later, you'll create new folders to replace these, to ensure that no corrupted file is reloaded to the Clip.)

Go to the Mac's Utilities folder. Launch "Disk Utility." Select Disk Utility's "erase" function. On the left, where disks are listed, select the Clip. Click on the "Volume Format" dialog box and choose "MS-DOS filing system." (Don't bother with any of the erase options, such as replacing all data with zeroes. Just do the basic erase.) Erase the Clip.

When erase is completed, drag copies of Clip's system files from Mac desktop back onto Clip icon.

Use "new folder" function to create new AUDIBLE, AUDIOBOOKS, MUSIC, PODCASTS and RECORD folders on the Clip.

Eject Clip from Mac and note whether the screen shows the Clip "refreshing" normally. If it does, you're in business.

When moving an item to the trash, it actually is just in a hidden ".Trash" folder on that disk, so no space is actually freed up. Can you try hooking the drive back up and then emptying the trash?

The link to the operating manual (which includes the Audiobook instructions) is here:

What I would do is drag and drop the Audible files from the folder that Audible creates to store your audiobooks to the Audible folder of the Sansa Clip, instead of using the Audible Manager.

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

Swithc from msd to mtp to uncover hidden files - also make sure you do not have hidden folders option selected in Windows itself

Try to connect your ipod and update it on internet. If it doesn't work properly, click start menu and point to search and then search iTunes.xml files on search files or folders.

If your audio book is in mp3 format you simply connect the USB cable to your unit and then drag and drop the mp3 files into the mp3 folder on the Nuvi650 device. If the audio books are in Audible format (.aa) then drag and drop them the same way into the Audible folder. Disconnect your unit from the computer and look for your audio book in the appropriate folder (mp3 or Audible) ... and no, mp3 Audiobooks and Audible Audiobooks are not the same format.
