I think he's trying to use the lingo for a low level format (LLF). That process writes zeroes to the whole disk. Meanwhile, a regular format, whether it's from Windows, FDISK, or Partition Magic, just overwrites the MFT (right?) so that it seems that data isn't there anymore. It's still available, until it's overwritten. That's why there's undelete programs that might work in recovering "deleted" data...because they're not really deleted yet.
If you want to prevent recovery, there's freeware file shredding utilities. Just Google it.
(I'm not at home right now, so no favorites on hand.)
It's best to format in DOS, for the reason that there's nothing else happening to disturb the rest of your system.
FYI: A low level format takes many many hours...it's like an overnight process.
I hope that helped!
