  • export phone data to USB medium

    From bad sector@21:1/5 to All on Wed Feb 12 12:43:03 2025
    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.

    At the end of the data backup there's a button that says "DONE", it
    could be that I didn't hit that and it could be that it meant "unmount".
    These nixish idiosyncrasies have been costing a lot of people a lot of
    grief methinks, immediate writing and unmounting/remounting as many
    times as required would be my way of doing things. Anyway, I'd still
    like to see a PURE-DATA-EXPORT for another reason: getting rid of all
    the non-data fluff which should really be kept in the phone if at all.
