My Hitachi DZ-MV100A stores video sequences in files
of type 249. It appears from DCN-5037 and DCN-5038
that they are "real-time" files. Unfortunately I
can't find mention of the "Mount Fuji 4" specification
that the osta points at.

    Look for Mount Fuji 5 on the t10.org web page.
    While making file type 249 reads/writes actually use the
    streaming commands is probably a pain, making access use
    normal read/writes (which should hopefully still work) is
    probably pretty simple

    It turns out that for the purposes of reading, type 249 can
    be handled in much the same way as a regular file is
    handled. This was just from my experience hacking inode.c
    to use file type 0xf8 in the same case as FILE_TYPE_REGULAR
    in the switch on (fe->icbTag.fileType).

    Handling FILE_TYPE_REALTIME just like FILE_TYPE_REGULAR
    (which has the unfortunately consequence of changing the
    type to FILE_TYPE_REGULAR if the file is changed on
    read/write media)
