The format operation frees up space on the physical or virtual storage medium for reuse. Modern operating systems allow such stripping in several modes - the user chooses them depending on how carefully the information stored on the carrier should be destroyed. The very same sequence of actions when formatting a disk for a computer user running Mac OS is not difficult.

Instructions
Step 1
Use the system application "Disk Utility" for formatting - it has the necessary function in Mac OS. To run this program, select the "Programs" section, then - the "Utilities" subsection, and in it, double-click on the "Disk utility.app" link.
Step 2
In the left pane of the application that opens, there is a list of available physical disks and virtual volumes into which each of them is divided - select the one that you want to format. Then click on the "Erase" inscription in the right panel and a short instruction with the order of actions and several controls will appear in it.
Step 3
In the drop-down list "Format" select the type of file system that should be used in this operation. The "Security Settings" button opens a window of additional settings - it contains selection elements that allow you to specify 7 or even 35 repetitions of this operation instead of one pass of data destruction. When making a selection in this window, keep in mind that the total formatting time increases in proportion to the number of formatting repetitions. In the "Name" field, enter the name of the volume under which the disk to be erased should be displayed after the procedure.
Step 4
Button with the inscription "Erase free. space "in the right pane is also associated with increased security - it performs repeated erasure of data, but not on the entire disk, but only on the unoccupied part of it. Use it if you want to once again overwrite the storage space with zeros that remained free after the previous disk formatting.
Step 5
After all the necessary settings for the formatting operation have been made, start the process by clicking the "Erase" button in the lower right corner of the "Disk Utility". The time it takes for the program to execute this command depends on the disk capacity, the type of communication interface used, and the security options you select.
