    ok, cool. that makes sense.

    now i'm having a totally different problem, actually: after figuring
    out how to mount it, i put about 500 songs on it, and then
    disconnected and reconnected it a bunch for various reasons.

    now, it won't mount read-write -- just read-only. when i try to mount
    it via the line in my /etc/fstab (which is

    /dev/sda /mnt/ipod hfsplus rw,user,noauto,noatime 0 0

    ), /var/log/syslog gives the error:

    Sep 27 16:12:48 homeruns kernel: HFS+-fs warning: Filesystem was not
    cleanly unmounted, running fsck.hfsplus is recommended. mounting
    read-only.

    and then it mounts it read-only, like it says.

    googling for this, i found a debian-powerpc thread[1] that says that
    after 32 mounts (which i probably did this morning), hfsplus
    partitions will stop being mountable read-write, and to use hpmount
    to get around this. i apt-got installed the hfsplus package with
    those tools in them, but trying to use hpmount gives me the following
    error:

    homeruns:~# hpmount /dev/sda /mnt/ipod
    hpmount: /dev/sda: Neither Wrapper nor native HFS+ volume header found
    (Unknown error 4294967295)

    which is just wack, afaict, seeing as it was mounting happily with
    `mount -t hfsplus` up until 32 mounts (and still does, just r-o).

    any insight how to get around this, to make my iPod read-write again?

    note: this has all been so far on my work computer, which is running
    kernel 2.6.6. i'm going to take this home and try it on my system
    there, which has a 2.4.26 kernel, and see if it's any different there.

    also, i'm using USB 1 here, and USB 1.1 (if that's at all different)
    at home. slow as molasses.

    thanks again,

    </nori>
