My sansa sandisk c150 doesnt work

the music db is corrupted...try formatting the player...if tht doesnt help,try upgrading the firmware

definitly a defective player send it back

Remove the microSD card and then delete one or more files from the Sansa's internal memory to free up an additional 90MB.

get a new one

To delete songs from your device follow the steps below
You have to make sure that the device is on MSC mode...then make sure your device is plug in to the computer..Then go to programs - accesories - windows explorer, find the SanDisk in my computer, go to media, music and delete them from there.
Either under sync panel in your windows media player it will show your music when it's connected. just click the plus signs for what song you need to get rid of, right click and click delete.
To format it..on your device..go under..menu, setting and there should be a format option option there..let me know if that doenst work for you...
Hope this helps

P.S.Please rate accordingly...
Thank You

are you able to format the player while in msc mode?

right-click on it while in my computer and select the format option, make sure your selecting your mp3 as this will delete all the files off the device. It if says failed to format, try doing it thorugh disk management. To get there you can right-click on my computer and select manage from the drop down menu. From here you will see disk management on the left hand side. Then a larger rectangular box with the drive letter that represents your player, you can right click on this and select format.

Or just try a different computer, if its the same everywhere then youll probably have to end up emailing sandisk, stating everything you tried. They will probably ask you to do a couple more things, but if you keep at it, youll end up with an RMA*.

*RMA = Return Merchandice Authorization

go to my computer when it is plugged up and delete the music from the harddrive of the player.

I have formatted it. No songs available when opened the playlist. But when I start the unit it shows "NoSpaceForDB Please Please Delete More Than4.0M.B". The property shows the "0 Memory is free".

most reliable way to clear the device is to use the firmware update utility.

version 1.005a can be downloaded here

If you've already cleared all the songs, might as well update the firmware (that solves most issues).
