  • smartdrv cdrom cache

    If you load mscdex first, smartdrv will cache the cdrom. To save memory,
    I reduced the smartdrv read ahead size. It defaults to 16k, I set it to
    8k.

    But when I installed software from cdrom I got data corruption. When I
    went back to smartdrv defaults the problem disappeared. Seems the cdrom
    caching fails when read ahead size equals element size.

    It worked when I reduced both, keeping the 2 to 1 ratio. There is some performance loss. Not big, but not wanted either.

    At least now I know how to work around the problem. shsucdx has it too.
    So it must be a smartdrv bug.
