Format a NTFS hard drive in 10.3
When I use OS X to clear a disk device, I use Disk Utility's Erase command (on the entire disk or volume), single partition setup, and the format option of writing zeroes. I never used the 8-times random write, since I assumed that would take longer (than zeroes). How much of a security risk is associated with just writing zeroes?

If you format by writing zeroes to the disk, an expensive (tens of thousands of dollars) data recovery company could get most of the data back. If you format with the "write eight times" option, a data recovery company won't be able to get any of it back, and it's unlikely that even the CIA would be able to do anything with it.

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.

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).
