disk wiping utilities

I thought "quick erase" just re-writes the FAT of the disk without zeroing the drive.

Low level format zero's the whole of the drive. ?
 
A low level format fills the drive with zeros or effs or both or anything u like (in some 3rd party examples) - point being here u will have no filesystem. This is in preparation for a filesystem to be formatted into place. A hard drive only ever `needs` 1 low level format in it`s lifetime. However if u want to vamouse any expectations of any1 back tracing tables to recover u`r programs (which is more than a long process in itself), u can do it and there is litterally nothing to retrieve, u`r drive is a blank canvas. U can also perform a low level format if u believe u`r drive is kaput and all the drive testing software out there is telling u it`s ok. If a low level fails, u`r drive is definately effed.

A quick format will wipe the bam, the table still exists, just isn`t in order.

One of the simplest commands u can write in machine language is to low level a device. Therein u can put ur name in the values being written ;)

The quickest way to securely readicate any1 reading stuff of u`r drive, apart from the fbi and more importantly the bedroom geek (who`d probably be quicker at it), is to clear all the tables. U got more chance of winning the lottery than extracting files then. Doing and understanding this process explains to u why filling u`r drive with zeros, or whatever, is just a waste of u`r time. As an example, take a spare 120g drive and low level it. Go to bed, wake up and it maywell still be going.
 
i prefer killdisk - as its a lovely piece of software, very customisable.

i love dban (Darik's Boot and Nuke) when u need to do batch low level formatting.

but killdisk ftw generally

Zero fiill is Low level formating.. It what they do when the disk comes out of the factory.. :D

No it isn't. Zero fill is when all the sectors are filled with zeros. A low level format re-defines all the sectors on the drive.

A lot of modern utilities are called "Low Level Format", they do work at a lower level, but do stuff like zero fill than an actual low level format, as doing so would probably break a lot of modern drives.
