I've been having issues with data backed up from an S-10 to FAT
formatted USB sticks. These (4 or 5 now) become to various extents
unusable following. Still investigating and I don't have all the info
but there seems to be a problem. The file system became read-only in
sone cases, in others the media become unrecognizable in assorted
COMPUTER OSes for unknown reasons. Samsung or android throw an alert
when the backup begins about some Samsung account password becoming
required to 'restore' from such data, which is ok when using the media
to recover from, but under no other circustance. At a minimum it seems
to me that there is a need to include in the backup menu a RAW-DATA ONLY
EXPORT (image, movie, document, whatever data files) all of which of
course should output read-write-by-all to any known filesystem.

There's a well know issue with jerking FAT devices out of a 'nix system
as soon as the 'operation' finishes. The problem is with buffering and
writing of the last of the data and the update of the FAT file for the
file changes.  The OS simply does not see a pressing need to flush the
buffers yet for a task that exited.  It will ..... eventually.

Since android is 'nix-ish, I would image the danger exists there, too.

My suggestion would be to power down the android -- which would force
the flush of the buffers.

Just a WAG from experience.
