Android did "something" to SD card

[v-600]

I am not sure if this is the correct forum but I'll ask away. I have a 16GB SD card (in the permanent storage) for my Aspire One. My housemate wanted to borrow it to see if he could read it on his android tablet.

On returning it, I found all the files had vanished. However the card still shows as full.

This is an odd terminal output and I can't work out what's happened to my files, and whether they are still there.

nathan@nate-laptop ~ $ ls -aR /media/1C25-1429/
/media/1C25-1429/:
. .. .android_secure LOST.DIR

/media/1C25-1429/.android_secure:
. ..

/media/1C25-1429/LOST.DIR:
. ..
nathan@nate-laptop ~ $ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 14G 6.6G 6.8G 50% /

udev 749M 492K 748M 1% /dev

/dev/mmcblk0p1 16G 14G 1.7G 89% /media/1C25-1429
nathan@nate-laptop ~ $

Any advice about recovering files would be appreciated, or any input into what the tablet has done to the SD card.

Can you mount your card back on the android tablet and see if you can read the files?

Aside from that, you might be able to get it to mount on a linux host somewhere and make a backup...

Either way, I'm guessing you'll need to format the card to clear whatever was changed to the card's file system.

That's not that "funny", most likely the free space count wasn't updated with the FAT. I would guess that he formatted it in his tablet and pulled it out without properly dismounting it, but that's just a guess.
