When you format a disk a percentage of the disk is reserved for a map so your 
file can be found.
On a UFS it is called the SUPER BLOCKS a master and at least one slave.

Typically these blocks will take up to 8% or there abouts of the disk.

BTW I am not shouting when "SUPER BLOCKS' that's how it's written.

In a root shell type fsck and watch the screen. 

For more info dig into you docs usually /share/doc or usr/doc there where some 
really good docs on the UFS.
