I hope this information helps. Thank you for using FixYa!

for reliability buy a dedicated micro sd reader as not all the adapters work.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

It sounds as if you have an SD card reader, not an SDHC card reader. While SDHC cards will fit into SD slots, they are electronically incompatible and will not work. SD devices are limited to cards 2GB and smaller. SDHC cards begin at 4GB and go up to 32GB.

that unit only reads a 1gb of memory card

Hope this helps, if it does please rate accordingly, David

Something is wrong with the card. Maybe it's corrupted.
But what your computer means by I/O Error is Input/Output Device Error, which means the card has issues.

Hope this helps!

The Sansa Express was only designed to hold up to a 2 GB Micro SD card because that is as much expandable memory it was meant to read. Anything bigger as in your case will cause the player to go slower than normal as it tries to read the card and after a while, it will most likely freeze. If you try it with a 2 GB Micro SD card, it should work.

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.
