    "ripped the support" is a bit nice for a thing that causes here
    a hard freeze.

    Famous last word:

    Jan 1 19:34:52 xterm kernel: MSDOS: Hardware sector size is 2048

    ext2 works, but it's extremely slow (compared to linear write using
    dd)

    "Don't do it then" is a bit hard, because I use "-t auto" on mount
    and both 2048 && 512 byte medias (yes, the girl that leaves my bed
    when I enter it uses msdos on 512b/sect medias).

    I don't know how hard a fix would be, I don't need it but I only want
    to avoid crashes.
