Many devices have a limit on what capacity memory cards they can accept.  The mp3 player may not be able to handle 4GB.  Check the manufacturers website for more information, or the instruction manual.  I have an old digital camera that won't take more than 128 mb, and a new one that won't take more than 2 gb.  Be careful about formatting cards.  I suggest that you only format them in the device itself, not in your computer.  You may make the card unusable if the wrong format is performed.

Subject: [PCBUILD] Formatting a Micro Card

Listers,

My son has a Sansa e250 mp3 player.  It has a 2GB memory inside, and a slot
for micro cards.  He currently is using a Transcend 2GB micro card that
works.  He just got a 4GB Sandisk micro card that can't be read in his
player.  I had to get a USB reader for it to be read in my computer.

I'm wondering if it needs to be formatted with a different format.  FAT,
FAT32, NTFS or exFAT.  I only have the FAT32 option on my computer, but have
all the other formats available on a newer Vista computer.  Do I need to do
a Quick Format or a long one?

What format do I need for this mp3 player?
