Now the FS is clean.

Does that say a.txt?

I didn't pull the disk out at all, or anything. Just umounted and remounted and made/removed a file. Also. . .

It appears dosfsck may not be working quite right. I've taken this into account, hence the second pass after each fsck. This is either a dosfsck issue, a usb-storage issue for the PNY compact flash drive, or an issue with vfat itself.
So either LKML needs to fix the drivers, or Ubuntu needs to upgrade/fix dosfsck or some patch they've applied to the kernel.
