what is "free space" format mean in Mac? - Page 2

post #11 of 12
Formatting a disk literally means configuring the disk with a file system. If you overwrite a disk with 0s you are erasing/wiping the disk. You cannot format a disk to "all 0s" because it is not a format/file system, you either have a format or you have no format, not both. The confusion with the term has come from term "reformatting", meaning to format again, which is the process of removing the current format / file system or even erasing the disk, then configuring the disk with a file system again; people have then associated the term 'format' with the erasure of the disk, when it only really applies to the configuring of the disk with a file system, ie the actual formatting process. If anything, overwriting a disk with 0s would actually be un-formatting the disk, but that term is usually used to describe the process of recovering the data and original file system of a disk after an accidental reformat.

Either way, nobody really cares about correct terminology, as long as we can all understand each other xD
