Top 10 SanDisk Sansa m230 MP3 Player Questions & Answers

I actually had this exact same problem with my Sansa m230, and I was running from place to place just looking for an answer; I actually stumbled across it through some related searches here on this site ('reset' specifically), and I tried it out and it worked for me. The Sansa m230 has two USB interface modes, and choosing one will make your system recognize the device differently than if the other is chosen, so songs that were uploaded using the USB setting 'Auto Detect' (which tells the thing to use something called 'MTP' mode) won't be visible again when it's connected using 'MSC' mode, and vice-versa. Simply put: Unplug the little bugger, go into the USB settings, and choose whichever of the two settings isn't already selected, and plug it back in. For the future, I'm going to erase everything from one mode and put it back in through the other mode, just so this doesn't happen again. <.

on mac - try going to view and selecting 'clean up selection'. not sure - i think it just worked on mine.

I had the same problem on my m230. The final solution that worked for me was to disconnect then go into settings;usb and set it to MSC. Once I re-connected I could see everything.

Hi big dee. Deleting songs from your M230 can be done by either browsing the player through your Windows Explorer and then selectively deleting the music file, or by formatting the player which would delete all of your music files. It's also important to know that your player has 2 modes -- MTP and MSC -- because music files saved in one mode would not be seen in the other mode, and vice versa. To switch the modes on your player, use the menu and navigate as follows: Menu > Settings > USB You would get a choice of "Autodetect" (this is for MTP) and MSC. Here's how to delete the files: Step 1: Plug in your player to your computer. Open explorer and check if your player is detected. Your player's LCD would display "USB Connected" and the mode would be indicated below that. If your player's mode is MTP: A. Look for the Sansa M230 icon on Explorer (it will be recognized as a Portable Audio Device). Double left click on it to browse the player. B. The player will have 2 sub-folders: "Data" and "Media". Double left-click on the "Media" folder and either find your music files or open the "Music" folder to find your music files If your player's mode is MSC: A. Look for the Sansa M230 icon and drive letter on Explorer (it will be recognized as a "Removable Drive". Double left click on it to browse the player. B. The player will have several sub-folders such as "Audible", "Config", "Record". You may already be able to see your music files or the player may have a "Music" sub-folder. Open that to check for your files Step 2 Once you've located your files, you may now be able to delete them. Step 3 Once you've unplugged your player, the M230's LCD will display the message "Rebuilding Library". Let that process complete, then you may turn on your player to confirm that the files have been deleted. To format your player, just right-click on the M230 icon in Explorer, then select "Format". When the Format window appears, make sure to select "FAT" as the File System type, and also make sure that the "Quick Format" checkbox at the bottom of the Window remains un-checked. I hope this info helps. Enjoy your M230. :)

I have the same problem too.. This sucks.

I loved that mp3 player, it's a great basic one. Anyways...

To unlock it, it require nothing related to your computer, it's on the side of your player, the old button.

Near the mic. I believe right now it's on a side with orange, tick it to the side that shows white. Open it again, should be unlocked.

Not to sure about a mac but I think mac's use a mp4 format when it rips a cd, and the Sansa will use a mp3 file. You can download a free program to convert these files but again, I know where for a PC but not a mac. Look for free mp4 to mp3 converter program for Mac..

You can download the driver from the manufacturer's web site at http://www.sansa.com

for you haven't convert the format of your music,i think.
