Erase and reformat a storage device in Disk Utility on Mac


The very important elements of Formatting the drive are contained in the Image within the supplied link


Side note - the computer will need to started from the Internal Drive to perform this action.


It can not be done if the computer was started from the External Drive that contains Monterey 12.5.1
