    I think it might be because reiserfs is a journaling filesystem. I know
    I sometimes forget and remove my usbkey (which has FAT) without
    unmounting, and don't see the problems you see. Even ext2 should be
    fine. Never tried with a journaled filesystem. Like someone else
    mentioned in this thread, it might be because the journal hasn't been
    updated yet. Probably is a bug in reiserfs too (it should recover more
    gracefully).

    BTW, checking the manual for mount(8), only ext2, ext3 and ufs supports
    the sync keyword).
