The extended partition itself is wd0s2, but you can't mount it, only
the "logical drives" inside it. These "logical drives" *always* start
at s5, so your (first) "logical drive" in your extended partition is
/dev/wd0s5, the second /dev/wd0s6....
Note, if you are still using 2.1.5 I don't think it supports extended
partitions.
