I'm surprised if there's any problem mounting either msdosfs or ntfs
'drives' in 'extended partitions' nowadays? There certainly wasn't in
FreeBSD 4.x, when I managed to get mount_hpfs going to salvage a number
of HPFS 'drives', all of which lived in the 'extended partition'.
The HPFS code (still in the source tree last I checked, but not compiled
by default) was written by Semen Ustimenko <semenu at FreeBSD.org>, who
also wrote the (then) NTFS code; the two shared lots of cut-n-paste.
It's true that information on this is a bit sketchy and harder to find,
but basically an 'extended partition' (in DOS parlance) uses one of the
four slices on a disk, for example let's say ad0s2, and the separate
'drives' that might appear as D:, E:, etc to DOS/'doze would be then
accessed as ad0s5, ad0s6 etc.

Try mount_ntfs using ad1s5, ad1s6 and ad1s7 then, read-only for safety.
