Hmmm... On FAT? I'm not sure. There might be a flag there that marks
whether the drive was dismounted cleanly or not. Or if you screw up the
root directory, I can see that mucking things up too. If there were just
a couple of directories, and the first sector of the root directory got
scrambled because she pulled it out while it was writing, I can see that
messing things up.

FAT usually has two FATs, too, for just such a reason. It's possible she
got a warning that the first was broken and just ignored it until the
second got messed up too.
I'm not real sure of the electrical characteristics of a USB stick such
that it gets the whole chip messed up by being pulled out while writing,
but I have to believe avoiding that was one of the design goals.
