Format a NTFS hard drive in 10.3
Authored by: johnsawyercjs on Apr 22, '05 03:22:09AM

Though there may be different terminology with *nix-based systems, the terms "volume" and "partition" have, on the Mac, from what I've seen since 1984, been two interchangeable terms for the same thing--all formatters for the Mac have used these terms to mean the same thing. I don't know the answer to the question as to whether volumes/partitions can also be called "filesystems", or if that's a term that applies to some other characteristic of the whole disk mechanism itself.

Disk Utility WILL let you erase, repair, etc. secondary volumes/partitions that are on the same disk drive as the Mac is currently booted from (meaning, not the volume the Mac is currently booted from, naturally), but Disk Utility won't give you the options to "zero all data" or the "8-way random write format" on any individual volume, whether that volume resides on the currently booted disk drive or on another disk drive--these two options are available only when you select the entire disk drive. Disk Utility also won't let you remove or resize existing individual volumes on any disk drive, except by erasing the whole drive.

File systems and partitions are not the same thing. A partition is a block of space on a disk. A file system is a way of organising the data in a partition.

Right ... the area within a particular partition (slice) may contain a filesystem, or may not. Also, there may be a logical volume in that partition, or not. In Mac OS, Disk Utility is employed to create HFS or HFS+ volumes, so there you have the "filesystem" (the "FS" in HFS).

In another case, in Unix when we use a disk device simply for paging (i.e. a "swap device"), since it's the entire disk then you don't need any partition map or label. But under LVM, we need to "initialize" (partition etc.) each disk device.
