• HPFS.IFS' /AUTOCHECK-setting

    From A.D. Fundum@21:1/5 to All on Sun Nov 15 15:44:41 2015
    What's the meaning of, for example, "/AUTOCHECK:G*"?

    The character "*" is not documented in eCS 1.2's "HELP HPFS.IFS". With
    Warp 4 this parameter used to be "/AUTOCHECK:CDEFG".

    G* does not make a lot of sense.
    The letters after AUTOCHECK: are the driveletters(partitions), that you
    want autochecked during boot.
    * means all (hpfs) partitions, which have a driveletter assigned.

    Most likely because you have created those 5 partitions.

    It is better to close your mouth, and look like a fool,
    than to open it, and remove all doubt.

    Allan, are you sure of that?

    I know the * with JFS means check all JFS partitions at boot but for
    some reason I have always thought that with HPFS it meant only check a
    drive if the dirty flag was set and the letter meant always check that
    drive (I think I got that info from one of the readme files with one
    of the fixpacks).

    Here I have the /AUTOCHECK:EV line and the partitions are only checked
    after a power failure/hard hang/trap when it is needed.
    I'd guess the * was added later, so is not documented and just covers
    all HPFS volumes.

    I'm afraid you got that wrong. * or any drive letter means check the
    drive, if it is dirty. Neither HPFS or JFS does eny check on a clean
    drive, but unfortunately JFS still displays something for clean drives
    (which is a bug).
    If you want to _force_ running checkdsk on a drive during boot, you
    need to add a + sign in front of the specific driveletter,
    ex /AUTOCHECK:CD+EFG
    will force chkdsk on drive E and check if dirty on the others.
    +* will force chkdsk on all drives - don't do that. It can take a long
    time, and if you have many or large partitions, the system may run out of memory
    during this - and can not boot !

    Basicly, the bahaviour is the same on HPFS and JFS.

    Hence the question. No big deal, I was just comparing CONFIG.SYSes
    w.r.t. old software without matching installers. AFAICT the behaviour
    isn't unexpected with dirty HPFS drives, so perhaps the eCS 1.2
    installer added a superfluous (last local) drive letter. Drive G:
    isn't checked twice.
