NAME

     diskutil -- modify, verify and repair local disks



SYNOPSIS

     diskutil [quiet] verb [options]



DESCRIPTION

     diskutil manipulates the structure of local disks.  It provides information about,

     and allows the administration of, the partitioning schemes, layouts, and formats of

     disks. This includes hard disks, solid state disks, optical discs, CoreStorage vol-

     umes, and AppleRAID sets.  It generally manipulates whole volumes instead of individ-

     ual files and directories.

Every once and awhile, Terminal is useful
