"Damaged USB storage": Anybody have a workaround?

I'm having a problem where an SD card that my Nikon has put images put on, is now deemed as "damaged USB storage" when I plug it into my Pocket Edge (either through the SD card slot, or with a USB card reader). This is definitely a Pocket Edge issue (and happens both on Dingo and Ermine), since Windows still reads the SD card fine and doesn't even complain.

I looked at the logcat out (below), and it seems fsck_msdos segfaults!

Has anybody else experienced this, or even knows a workaround?

Don't know for sure, but could it be that the card is a format that android can't read, though that would be a bit odd given that the camera can, still something to check if you haven't already.

Issue resolved. Turns out that the Nikon camera mangles the FAT32 file system so that fsck_msdos dies upon trying to repair it (this is not a Pocket Edge issue, but a wholesale Linux issue. It seems fsck_msdos is in a very shoddy state).
Well, I found out that as long as I format my SD card in FAT16 instead of FAT32, PE can read it just fine. Limits the card size to 4GB which is about 800 pics on my camera, but that I can deal with.

Glad to hear you sorted it out!

Actually, I don't think that fsck_msdos is Linux at all - it's osX, from BSD. The linux fsck commands would be just fsck with a -t parameter if it doesn't detect the file system, or fsck.msdos or, (for FAT32) fsck.vfat. Not to say that those could have handled your card any better, but it'd be vaguely interesting to try (not interesting enough to re-reformat and then find someone w/a linux machine). Besides, it's always fun to get in a little Apple bashing, even if only sideways.
