That's different then.  If you want to keep XP (and keep it within that
extended partition) then you can't delete the extended partition.  You
could use Partition Magic (ono) to delete the linux logical drive, then
shrink the extended partition to make space for another slice (maximum
of four), which is what you'll need for another UFS slice.

You won't - fdisk sees the four slices only, the 'extended partition'
being one of those entire, with it's specific type.

What does just 'fdisk' say? (you can do this anytime, it just lists)

The view from linux &| XP fdisk may be useful also.

Definitely to be used with due care.  I generally prefer trusting
sysinstall to be good with the maths - but keep a beady eye on it too.

You can mount them, readonly anyway, knowing that the first 'logical
drive' within the 'extended partition' appears as ad0s5, the second as
ad0s6 etc, assuming ad0 of course.
