If your memory card shows less space then it is either corrupted or virus infected. You should try formatting the card to correct the problem. If you want to recover data then you will need to go for memory card recovery software.

I release this thread is old and has been bumped, but this is incorrect I have used a 32GB SDHC Card and currently use a 64GB SDXC Card with no problems.

One thing that can make the card show as "corrupt" is, if you have swap partition(s) on it and the first partition isn't your data one.

Did you try to check the file system of the partition called N900 , you need rootsh installed to get this working:

Code:

sudo gainroot
fsck -af /dev/mmcblk0p1
fsck -af /dev/mmcblk0p1

Yes, do it twice.
If no errors remain, you might reboot to check the state of the mass storage.

If you care about your data you can recover it with Photorec of testdisk later

I am sorry, willi6868, but it looks like a hardware error. Flash cards do not last forever. I suspect your card is a goner and your data with it. There is a VERY small chance that something might be retrievable but I would not hold my breath.

You can try:

Code:

root
ls /dev/mmc*
sfdisk -l

to see if the card's hardware is recognized at all.

I once had a card that suddenly failed. It was an 8GB card. Following the failure, any system I tried it on recognized it as a 32KB card and could not write to it. There was no chance of recovering any data from it. Family pictures from the last two holidays gone just like that.
