Not working hai my name is vinod.iam using the sansa m230 512 mp3 player.it was not detecting by my system.as i connected to my computer it asks me to "sync files by windowsmediaplayer,take no action"ichanged the usb options to msc.but there is no use please say how to solve my problem.i get frustrated by my player .i installed my drivers also.

use windows media player... open WMP connect your player it should recognize it... use this to sync music to your sansa...you highlight the songs in WMP right click ... go to add music .. select sync .. once you get the songs into a sync list ... you just sync the sansa...

(using your computer) plug it in (running usb or discoverable mode) and you should be asked what to do with the digital media (or audio) player. Select open with (your favourite media player eg windows media player or songbird) then use the application to add/delete your music (then sync the player)

I had the same problem when I connected to the computer. So I used my friends Labtop definite 2.0 usb. Did you try to update your sansa click on link and download install run connect sansa when asked.

this has the manual also Make sure USB mode is MSC I use my computer to drag and drop my music from my music folder to the sansa media folder.... Open my computer click on folder what ever folder has your music in it and drag to media folder and drop (click on the (+)where it say's sansa ) easier not to sync

I hope this works

If your sansa 'fuze', right dosen't like your media get the sansa media converting software, My Fuze came with a mini-cd, if yours didn't you can download the official sansa media converter on
www.sansa.com/downloads
I hope it works for you! -Aptera P.S. I have no clue about MAC OS

I had the same problem, all you have to do is first turn on the Mp3.Then go to settings. Then go down to USB mode. It will probably say, auto detect.But instead scroll down to MSC. If that doesn't work try MTP.

When you plug an mp3 player into a 2nd computer with a different operating system, a reformatting takes place, rendering it unusable on one computer or another without reformatting the player

Danger: reformatting a player will erase all of the songs on that player

There are two ways to format an Mp3 player - one on the computer itself, and one in Windows Media Player. Both methods will end up erasing all the songs on the player, but the player will be "good as new" after that. Sometimes reformatting in this manner will override the player's native formatting and cause problems - this can be reversed in most cases by updating the player's firmware. Firmware upgrades are available from most manufacturers' websites.

WARNING: The following procedures will erase all songs on the player.

Check if the file system is NTFS. If yes, format it to FAT or FAT32. - Connect player to computer, double-click my computer, right click on icon of mp3 player and select format. This only applies to Windows-based computers.
You can also format the player in Windows Media Player itself:
Connect your Mp3 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 "name of Mp3 player here 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.

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/Retail/DriverDownloads.aspx

There are a few different ways to delete songs off your player.

Preventive Medicine: To prevent Windows Media Player from adding all of your My Documents files to the Sansa player every time you connect the Sansa to the computer - 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 "Set up Sync". When a window pops up, uncheck the box that says "Sync device automatically".

Quick Method 1 - 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.

Quick Method 2 - Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once.

Slow Method, allows more control over what gets deleted: In Windows Media Player 11, the files are organized by Music, Pictures, Videos, Etc. First, you will want to plug the Sansa player into the computer. Then click the Library tab in Windows Media Player. You will most likely be in Music view. You will see two sets of folders in the left-hand side of Windows Media Player. The first set are all the files stored in your computer. The second set of folders underneath the line that says Sansa 1GB Mp3 player (I forget the exact wording) has all the files that are stored in your Sansa player. Click on the "All Songs" folder. You can individually delete all the songs that you want by left-clicking once on the song name in the middle of the Windows Media Player window, and then pressing "Delete" on your computer's keyboard. You will have to repeat this process again for images, videos, etc by clicking the little arrow next to the picture of the musical note on the upper left hand corner of Windows Media Player, and expanding the dropdown menu, and selecting "images"...then "Videos" etc.
NOTE: After plugging in your Sansa player, if you see a message that says "Connect a Device" in the Sync tab on Windows Media Player, then the cmputer is not properly recognizing your Sansa player, and you may need additional instructions from me.

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.

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.
