8/10    I have an disk on /dev/ad0 (freebsd) with two slices--
sysid 6,(Primary 'big' DOS (> 32MB))
    start 63, size 3068352 (1498 Meg), flag 80 (active)
        beg: cyl 0/ head 1/ sector 1;
        end: cyl 190/ head 254/ sector 63
The data for partition 2 is:
sysid 5,(Extended DOS)
    start 3068415, size 9510480 (4643 Meg), flag 0
        beg: cyl 191/ head 0/ sector 1;
        end: cyl 782/ head 254/ sector 63
        I can mount /dev/ad0s1 but "mount_msdos /dev/ad0s2 /mnt"
        returns "mount_msdos: /dev/ad0s2: Invalid argument"
        Why is this?
        \_ Have you tried /dev/ad0s5 instead? I believe 1-4 are for primary
           partitions.
           \_ tried that, and it didn't work.  I really think it's in
              partition 2, as sysinstall fdisk reports that.  Disklabel
              only shows a tiny little freebsd slice that I put there to
              see if it's actually being written.
