Sansa C250- accidentally formatted using MAC

Use the supplied Sansa Media Converter program to convert your photos (and videos) to a format the Sansa can handle. If you don't have the SMC, you can download the Windows version from

You can. Just make sure you put the USB into MSC mode, so the Mac will see it. You can just copy files to it with Finder and use it like any other MP3 device. Also eject it before you remove it from the Mac. For MSC mode go into the menu and go to Settings and then select USB and finally select MSC.

I have the same problem...
It sucks

You can't plug the same mp3 player into a MAC and a PC - one erases the formatting of the other. Run the Sansa Recovery Tool for the c200 series - it is available from the Sandisk website. Also, here is a link to the full user manual:

You must find the Sansa c250 menu that allows you to format the microSDHC card for use with media player.  Most microSDHC  cards are shipped unformatted.  It is a new technology and there is no standard format for microSDHC cards as they are used to store many types of data.  My cell phone uses one to store music, video,and photos, so the phone's manufacturer included a format command choice in the appropriate "phone memory" menu.  Look for the microSDHC card in a "memory" menu. Follow the prompts to format the card.  This only works on a NEW card.  If you format a used card, ALL data will be lost.  Formatting a card or a hard disk effectively prepares the memory to be written on, erasing any data previously written on it.

I first suggest that you use Windows Media Player on transferring songs to the player. Rhapsody is a p**n in the a** when i use it to transfer songs to the player. Well back to the topic, make sure the device that you have is set to MTP when you are transferring songs to the player using rhapsody.. If it will not transfer format the player using Settings and then FORMAT if it did not work format the player in MSC mode. To do this, go to settings then to USB MODE then change it to MSC and then connect the player to the computer. After connecting the player to the computer ti will be detected as a removable disk drive. Right click on it then choose FORMAT make sure the file system is FAT32. THen after the format is done. Chnage the mode back to MTP then transfer a song using rhapsody. If all else fails using the windows mediaplayer program. Here are the instructions on using the windows media player program.

There isn't software, because the software is not Mac-compatible. Sorry.

Mine froze up and I just took the battery out. Then it stopped freezing up.

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.
Download the Sansa Recovery Tool from the Sansa website.
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/DriverDownload/driverList.asp
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.
