$ diskutil info

$ diskutil mountDisk
diskvol
To erase and repartition a disk:
$ diskutil partitionDisk

Because HFS+ is case preserving but not case sensitive, there may be times when you
would want to set the file system to be case sensitive. You can use the diskutil tool to
format a drive for case-sensitive HFS+.
Note: Volumes you format as case-sensitive HFS+ are also journaled.
