Hi,

I was downloading a file and I had xterm open to the directory I was downloading to (a 2 GB miniSD card) when I did an 'ls' to check the progress of my download. I repeated the 'ls' again only to find that ALL my data on the card had disappeared. Is there any way to undelete this data and could I reformat the miniSD in, say, ReiserFS to avoid loosing data again?

Thanks,

VS

First, I would check to see if it just didn't unmount itself. Just remove the card and put it back in. If it's really gone, stop using the card until you are ready to recover the data. I'm afraid I can't help with that part.
As for ReiserFS, you will need a kernel module, but it shouldn't be too hard.

I have used this program in the past to recover deleted items from SD cards. Maybe you could give it a shot.

you were right, the card did unmount itself. I simply took it out and put it back in and the problem was solved. Why did it 'unmount itself'?!?! How can I prevent that from hapening again? Could I have simply mounted it back from the CLI?

Out on a limb: Any chance the card door wasn't properly, entirely, completely closed the first time? I've had the same thing happen once and I've been quite religious since in checking that the flimsy card door was indeed properly closed and clicked shut. Never happened again.

Chalk it up to yet another one of Nokia's Amazing Design Decisions: the door on the 770 was much better in that respect.

Right again! I think the (crappy) door might be to blame. That, and the fact that my miniSD uses an adapter (and costs 11$ on amazon.com for 2GB making its quality dubious).

Well, at least the card did not somehow logically 'unmount itself' (I almost had a heart attack when I read this one ;-)
