Thanks for your reply Matt.

Here are the steps that i followed from command line (after 
logging as root).

# disklabel64 -W ad4s2

# fdisk -B -I ad4

# dd if=/dev/zero of=/dev/ad4s2 bs=512 count=32

# disklabel64 -B -r -w ad4s2 auto

Now, while i donot see the error message mentioned above, but 
on executing each command the following message is seen:

ad4s2: cannot find label (no disk label).
>>> Exit status: 0

The installer continues ahead, but on reboot, the boot loader 
stalls with the message 'no ufs partition' !
