I couldn't find Sansa on my computer when I connect with USB cable!

Go into the device manager by right clicking on my computer, hitting manage, and highlighting device manager. Expand the usb devices section and see if there are any unknown devices listed. Hit view Show hidden devices if you cant find anything. Remove anything that says unknown device. Take out the device from the computer, install the most recent software from their website. Connect the device back.

Go into the Sansa m200 menu under Settings -> USB and select MSC instead of Auto Detect.

The solution recommended by "karinb" worked for me. To explain in further detail, unplug the USB cable, then click on the menu button on the side until you see the first main menu screen (it says "play music", "FM radio", etc), then scroll down the main menu by pressing with your finger on the words on the right side that say "repeat / AB" until you reach "settings" on the second screen, then click the white button on the right, then scroll down the settings menu until you reach "usb" on the third screen, then use the scroll button(s) so that a checkmark appears beside "MSC" instead of beside "auto detect", then press the menu button to exit the menus, then plug in the USB cord and see if you can now see the "removable disk" drive in Windows Explorer and follow the manual's instructions for copying music files to the MP3 player.

Go onto settings, and change the usb to 'MSC' mode, then connect it to your pc with the usb cable and your flying!

Im having the same problem but the Msc thing will not work infact the sansa does not even say its connected when it obviously is

I am having m200 Series MP3 Player (m240 version-3.28A). 1 GB. I donot know how to use it. Where can I get a user guide.
