    you mean, like, remount -o rw,remount /dev/sda2 (or whatever device)?
    -- no, i can't. tried that; should have said.

    yeah, i couldn't find one.

    hm, probably ... but now i converted it to vfat.

    it's entirely possible.

    on mine, it's /dev/sda2 ...

    apparently the hfsplus tools figure out which partition on the device
    given has the data you want for you -- magic! so, that's legit when i
    mount with -t hfsplus, but not when i do it with -t vfat.

    now, i'm getting a weird problem, however. after dumping about 200
    songs on my newly-vfat'd iPod, i tried to add another batch, and
    gtkpod crashed, and my kernel told me:

    Sep 28 12:14:44 homeruns kernel: FAT: unable to read inode block for
    updating (i_pos 1219121)<3>FAT: Directory bread(block 76088) failed
    Sep 28 12:14:44 homeruns kernel: FAT: Directory bread(block 76089)
    failed
    Sep 28 12:14:44 homeruns kernel: FAT: Directory bread(block 76090)
    failed
    Sep 28 12:14:44 homeruns kernel: FAT: Directory bread(block 76091)
    failed
    ...
    ...

    and so on, for about 100 lines.

    now i can't mount it. i get the error:

    mount: /dev/sda2 is not a valid block device

    when i try. when this happened the first time, i tried rebooting (i
    know, bad linux user! shouldn't need to reboot), and that solved the
    problem until it happened agin.

    i'm going to try this on a friend's mac tonight, but what's up? do i
    have a lemon? why is the filesystem suddenly ceasing to be
    unwritable?
