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. John
