"Completely" Cleaning a Hard Drive
I'm hoping for a tool I can use on some harddrives I bought (used). I want nothing on them that can mess me or friends around later. I'd like a program I can put on a floppy or CD (free), and hoping for one like the government uses. I want to clean these puppies before I dare use them. I want to go beyond the "zero-fill" tools the drive manufacturers offer, because I understand even those aren't fail-safe. I can use these drives in PCs for others; building some cheapos for 2 folks that can't afford a new PC, and don't want something on them that could cause them problems. Me being too paranoid for my own good, I want to start absolutely clean. Something I can put on a floppy or CD - safest, best and free.

It's free, it's effective and it's easy to use. http://dban.sourceforge.net/

From your link - "DBAN prevents or thoroughly hinders all known techniques of hard disk forensic analysis.' What's that?

It writes zeros so many times that it makes it real hard for the FBI to get data off them. It is time consuming to do DOD-level wiping, but very effective.
DBAN is on the Ultimate Boot CD if you ever downloaded and made one. You should, it's a very handy tool to have, you don't have to go downloading a whole bunch of stuff, it's all on one CD. |

It does not have DoD approval but it uses DoD methods. It appears to use 7 passes - this takes a while.

Free Killdisk is only a single zeros pass. Not even close to DoD.

Sarge. any idea what make these hadrdrives are? from what I have found none of the above listed utilities will do a good job on Hitachi harddrives, you must use Hitachi's own software.
I was formating a Hitachi harddrive last night and all the utilities on the UBCD failed, they actually dumped me out to the DOS screen, I had to use the HItachi software and I am not sure if that actually does a zero fill it may only be a low level format.

A "low level format" on an IDE or SATA drive is a simple zero fill. A true low level format is only used on SCSI and MFM drives, using that on an IDE will destroy the drive.

I'm thinking maybe 8 hours? I dunno - I never used that thorough a wipe.

Depending on the size and speed of the drive; it takes a couple of hours.

That is not a zero fill, that's just secure file deletion.
