Oops, small self-correction here, I forgot, this is in the way FAT
works. FAT12/16/32 writes look like this:
1) Write data.
2) Update FAT table 1
3) Update FAT table 2
If you loose media during any stage, you'll end up with the following
respectively:
1) Garbage clusters.
2) A corrupt FAT1 table, but a clean FAT2 table and lost clusters.
3) A clean FAT1 table, which is correct, so you can update FAT2.
Of course, *nix can use near-any FS on removable media besides FAT,
which may not be so robust, which is why it's not so simple to just pull
out the drive, hence our situation.
