2gb Sansa Fuze won't recognize 2gb Micro SD

Make sure the music is in a folder named "MUSIC".

Sansa C240 can only read SD cards that are NOT SDHC - that means it can only read up to a 2gb Micros SD card.

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.

First, make sure it's a microSD card and not a microSDHC card. If it's larger than 2GB then it's a microSDHC card and won't work. Second, make sure all your music is in a folder named "MUSIC".

There are 3 ways to solve your problem, but all of them are rather kludgy. This is an old player and the integration of the microSD card is not done very well. I believe with the newer players these sorts of issues are not problems. Anyway, here are your 3 possibilities:
1) You can load your music directly onto the card before you put it into the player. Most cards come with an adapter that lets them fit into slots that are for regular SD cards. So if your computer has a slot for an SD card (or if not, you can plug the card into a card reader and then plug the card reader into the USB port on your computer) then you can copy and paste mp3 files onto the card. This is a drag because you can't use Windows Media Player to do this, but instead need to open the folder where the MP3 files are and then copy and paste them onto the card. But it works
2) This is slightly easier. Before you connect the Sansa player to the computer go to the settings part of the main menu and then select mode. You should see two choices. One is MTP and this is the setting you want if you are using the player with Rhapsody service. The other setting is MSC and this lets your computer recognize the Sansa player AND the microSD card. Once you have selected the MSC mode, then you can connect the player to your computer. When you look at the drives on your computer, you'll see 2 new drives. One is the Sansa 280 and the other is the microSD card. Once you see those, you can copy and past MP3 files right onto the card (and/or onto the Sansa). Again, you have to go the folder where your MP3 files live and cannot use WMP to do this
3) I haven't tried this, but others say that a free program called rockbox (www.rockbox.org) let's all this work much better. It sounds complicated, as it puts kind of a new operating system on your Sansa and it may not be reversible, so proceed with caution, but some people love it.
Hope that helps

Check the Sansa tutorials at http://www.sandisk.com/Retail/Default.aspx?CatID=1468
to make sure you have followed all the steps first.

In my experience, every mp3 player/photo frame/etc with a card reader has a MAXIMUM memory limit for the type of card that it can read. It is possible that the Sansa player can only read 2GB Micro SD cards or smaller - and thisi nformation may not have been available when they printed the manual. If you have followed all instructions, and it still will not read the card, try switching to a 2GB Micro SD card.

If the 4gb micro SD is a high capacity SD (it will say micro SDHC on it) your player may not be able to read SDHC cards, my sansa can't because it's the 'older version' it will read 2gb and below micro SD cards though (it sucked when I found out because I had just bought a 6gb micro SDHC)

Go to the knowledge base on the Sansa site and find this (chances are you have an SDHC card in an incompatible unit):
Sansa e200 - verify the version of the player.  To check, go to SETTINGS > INFO. 
              
For 01.xx.xx firmware (e200 version 1) - up to 2GB microSD cards 
For 03.xx.xx firmware (e200 version 2) - up to 16GB microSDHC cards 
NOTE: Firmware is not interchangeable. 

Sansa e200R - up to 2GB microSD cards 

Sansa e100 - supports SD cards up to 2GB 

yes you need to put music in the micro sd seperately.
