I have a Sansa e250 I have put a new Micro sd card with 8 gb memory into the card slot it has music loaded on to it ( when it is in the computer it comes up and shows what is on it ) the player does not show this card and shows it is empty I have formated the player.

The e250 uses microSD cards, not microSDHC cards. The maximum size of microSD cards is 2GB. Anything larger are microSDHC cards.

your reader does not support the 8gb device, look for firmware upgrade for the reader

Hello,

The micro card (the smaller one) can be used alone in a port that accepts (microSD ports)such as those on a Sansa c240, c250, e250 etc.
If you have a regular SD slot (larger than microSD) then you plug the micro card in the adapter and plug the whole into a regular SD slot.

Plug the card in your computer and copy paste the files. Or plug the micro card in an MP3 player that accepts it and use you music transfert software.

You only have one card (the micro SD one), which you can use in two possible slots.

Hope it helps.

Sorry, it doesn't work that way. You can use a separate card reader to put files onto the microSD card. When the card is installed into the Sansa, the Sansa will see the additional music.

It's pretty simple really. To actually get music on your micro sd card you have to put it into an adapter and connect it to your computer. Then you have to put the music on the card seperately. Then plug it into your sansa and it will recongnize the songs and play them like normal

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.

it might not be possible. sorry.

According to what I've read, you can double the original memory, but no more than that, so the max you can have on a Sansa e250 would be 4 GB (2GB internal memory and 2GB external memory). I also read that the micro SD cards holds
music only-no video.

If music won't load onto Micro Sd card:
1) go to settings
2) go to USB mode
3)change to MSC format

Now you're good to go.

It should work if it was made by Sandisk and if it is a Micro SD memory card.
