disk partitioning

Total disk size is 38912 cylinders
             Cylinder size is 32130 (512 byte) blocks

                                               Cylinders
      Partition   Status    Type          Start   End   Length    %
      =========   ======    ============  =====   ===   ======   ===
          1                 IFS: NTFS         0  9560    9561     25
          2       Active    Solaris2       9561  25496    15936     41
          3                 IFS: NTFS      25497  28683    3187      8

From above, it is obvious that i have only use 74% of my hard drive. I am trying to create a new partition that my solaris 10 x86-64 will be able to us as backup. i was thinking the following step of command will be appropriate

format->fdisk->create partition (unix partition type)->"starting cylinder from 28684"

pls can someone advice if this is the right thing to do as i am a newbie.

yes..using that metode first convert that 25% free space in to UFS. and later create the Logical particitions in it.

I have done this successfully pls how do i logical partition in it
