WHENEVER I TURN ON THIS SANSA MP3 PLAYER ALL SEE IS A READING THAT SAYS "DOES NOT HAVE ENOUGHT SPACE FOR MUSIC DB. PLEASEFREE 90MB" WHAT DOES THIS MEAN.

Just to be clear,most players require no special drivers.
Try this tip posted here on this site. You will see there are two sides to your player. One cant see the other.

Having gone over a month with no response, I assume this is no longer a problem.<!-- from fixya rte -->

Plug it into the USB, then select the drive in XP " my computer " or in vista/7 " computer " and open the device location. you should see a music folder in the main directory and from there right click and delete any song or folder on that device.

There needs to be some space for the part that finds and tracks the songs. There are too many songs/pictures/video on your Sansa. Remove some. Its always good to have some extra space. Don't fill it up completely. Always leave 100megs free when loading the player.

you need to free space so it can use the firmware

The only thing to do for this error is goto My Computer/Computer and right click on the Sansa player, choose format.  Select Quick format.  It will delete all data but at least the player will work again.

That player is not compatible with iTunes - sorry. Loading them onto there has corrupted your DB - go to Sansa'a website and download the Sansa Recovery Tool

What has happened is that when you connected the device to the computer if automatically downloaded everything on your media files thus filling up your MP3 player
You need to go in and delete the files you do not want. click the bottom part of the disk or dial and it will show a menu to delete FIRST,
you must let the battery run down(disconnect the cable and when the battery has discharged, you can plug it back in to recharge, then you can work with it to delete some of those files that are overloading you device This happened to me and this was the only way to unlock it when it locked up

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

whenever i turn on my sansa m230 mp3 player, it displays the message, "not enough space for music DB, please free 8mb." And so i plug it into my friends computer and when i open the music folder on the device, its empty, even though it says that there is quite a bit of space used up. Do you have any answers?.
