diskutil eraseVolume format name MountPoint|DiskIdentifier|DeviceNode | |
Erase a single disk partition or whole, laying down a new file system volume | |
that will be empty of files. Format is the specific file system personality | |
name of the new volume, e.g. "Journaled HFS+" or a common alias e.g. "jhfs+". | |
Name is the new volume name (subject to file system naming restrictions) or | |
can be specified as %noformat% to skip initialization (to skip newfs). You | |
cannot erase the boot volume. A pseudo-format of "free" or "Free Space" will | |
remove the partition altogether, leaving a free space gap in the partition map. | |
Ownership of the affected disk is required. | |
