first of, you don't need a directory in a newly created partition to mount it.
you can mount devices too.
e.g. mount /dev/hdc1 /newdrivemap
(/dev/hdc1 is the new partition, wich will be aviable as /newdrivemap on the system)
so to mount your partition on the system, you could initialize the mount command with the correct parameters.
(also you could enter the partition into the fstab, so it will be mounted on boot time.)
