My new 8Gb Micro Chip Will not except music

It's not the computer, it's the Sansa. The e260 uses microSD cards, which only go up to 2GB, not microSDHC cards such as the 16GB one you have.

Sandisk sansa e200 series players only allow up to 2GB expansion, BUT with rockbox firmware up to 32GB is available. Only download rockbox firmware if your familiar with transfering and installing files.
Rockbox firmware can be found at http://www.rockbox.org/

i think you put it back again your 2GB micro chip, its not necessarily to put 8GB, it will not work.. Your sansa e250 is design for 2GB only, your not an inventor to do that... your only a user, if you something stupid on that, its your own risk but for me its not necessary, your not contented with that.. All you have to do buy a new one which a lot more than 2GB and up, right!... Don't be so pathetic to do that things, even the company don't want really to change even the micro chip inside.. They were not selling for that kind of MP3 player... if might be then they will loss profit on their product, youve been pirate on it... hope you understand the situation...

Go to my computer scroll to sansa or your MP3 player and open the music folder and open each sub folder and delete Songs manually then delete the folders them selfs then format a couple of times hope this works

The Sansa, in common with many devices which have been around for a while, will only recognize standard micro SD up to 2 GB, not the SDHC (High Capacity) variety.

Check to see what format the files are saved in the new ones might not be in the right sound format for a sansa

please post me a sansa e260 driver and installion software

I read somewhere that a 4 GB Micro SD card is the largest you can put in the SanDisk Sansa E260 expansion slot. It's maximum capacity is 8 GB, with internal + external memory put together. This is from what I've read. Hope this helps.

The Sansa is unfortunatley one huge mess up the programming has failed its working on a database with only 4 levels but for grphics and songs you need at least 7 lhopefully you can return it and get another if not you can try putting another type of chip hopefully that will work
