How to "mirror" partitions

I have a PC with two HD, one is a
4 GB and the other a 2GB.
The 4 GB has two partitions one is
FAT and the other NTFS. The 2 GB has
one NTFS partition.
Everytime I try to mirror the NTFS
partition on disk 1 with the NTFS
in disk 2 the "Fault Tolerant" menu
shows me all the options DISABLED
giving no chance to make the mirror.
Is it possible to make a mirror from
a partition into a second full disk
or does it has to be between complete

Remove the empty partition you want to mirror two.  Then select the one you want mirrored and the empty space.  This should give you the option to mirror.  (The non-partitioned space on the other drive must be equal to or exceed the size of the drive to be mirrored).
