I have a Benjie pocket music player. One of its many issues is inability to order a directory of files by the filenames. Turns out that happens to be a common problem in players https://superuser.com/questions/376577/how-to-reorder-the-files-of-a-fat32-file-system
But when I happened upon fatsort in
my Debian/WMLive repos, it said the FATs differ, and refused to
proceed. So I wanted to inspect the FATs. I was lazy enough to only
use things I found in distro repos, so i didn’t even bother reading
the help of finds like fatutil if they weren’t in the repos
Anyway, minfo -i /dev/sdc :: was
complaining something about the device being zero-length. I found
fatinfo in the repos and it was
complaining on the sector size being 1024 and not 512. Too bad,
because fatinfo was the one that would have allowed me to merge the
FATs. fsck.msdos only asked me which
FAT should it proceed with, the first or the second. Ended up going
with the first, and all the files seem to be there.
