You are not obliged to do it. You just have to know which one to delete=20=

or to partition (use L command to list (rule ;) ) them all) ... See=20
next point.

If you have already 4 partitions and you want to delete partition 4 for=20=

example, you just have to type
d 4p
and to create use
c 4p
and this will automatically take the beginning of the original base=20
block. You juste have to specify  the number of block you want to give=20=

to your new partition with 2*1024*amount_in_MB (if you want a 256MB=20
partition, then you have to give (2*1024*256) blocks  -- and for GB you=20=

have to multiply again with 1024).

No, because once the partition created, I used Disk druide to set the=20
mount points ... And by the way, pdisk creates Apple_UNIX_SVR (?)=20
types.
