Low level format, or dban
How do i do a low level format? or how do I use dban?
<-- noob =]
Go to http://sourceforge.net/projects/dban/Quote:

Boot the CD, follow the simple instructions (and make sure you select the correct partition to be nuked!!!)
Most HDD manufacturers provide their own tools for LLF, or use http://hddguru.com/content/en/software/ but I'd personally dban it. http://www.dban.org/faq
*edit ^What dangel said^ :)
There's also a utility that uses the secure erase function built into modern drives: http://cmrr.ucsd.edu/people/Hughes/SecureErase.shtml but personally I use DBAN. If using DBAN, the best method for modern drives is a few passes of random data - I'd say choose at least 3 passes but it does take a fair while. If you just want to zero drive to get rid of MBR viruses or whatever a quick erase (fill with 0s) is plenty.
+1 on DBAN.Quote:

To an average home user, yes but to anyone who really wants the data, no: http://www.cs.auckland.ac.nz/~pgut00...ecure_del.html
Yeah, not many people are going to go to the length of recovering erased data but random overwrites are not 'not necessary'. That's a bit like saying AES isn't necessary because not many people would bother bruteforcing DES, or WPA2 isn't necessary because not many people would bother breaking into WEP.
The Gutmann paper has been challenged many times since it was originally published eg: here, and Gutmann himself later acknowledged that the chances of recovery on a modern high-density drive were vanishingly small.Quote:

hey again
i tried to use dban last night but it just wouldnt work
i think i am ment to get the blue screen like in this guide:
http://www.csuchico.edu/usrv/securit...structions.pdf
but after i get it to start, it goes straight to a black screen saying like:
no errors......
started:....
finished:....
saving to removable drive....
any ideas?
What mode are you drives in? I've heard of problems with AHCI. Try putting them in normal IDE mode if so.
IDE i think, dont know what AHCI is :p
Personally I wouldn't use any 'format' function from a hard drive mfr because you don't know what the software is doing - unless the software actually says that it is re-writing the internal logical structure of the disk, you can't assume it.Quote:

For a home user, overwriting with zero is more than sufficient.Quote:

If that is of concern to you, get the angle grinder ready.
DBAN is somewhat more refined version of the basic linux dd command. You can clean a drive by using a linux live CD and the dd if=/dev/zero of=/dev/<device_name> where device name is in *nix nomenclature, eg sda or hda (or if you justt want to erase a partition sdan or hdan where n is the partition number. A search on Hexus will give more details about linux device numbering and the dd command if you need it.
Use the Beta version: http://sourceforge.net/projects/dban...6.zip/download the latest stable release isn't fully compatible with newer computers. As mentioned on the site the Beta works fine, it's just not yet called a stable release basically. :)Quote:

There are always 4 of these "unrecognised device" no matter how many drives are plugged in, tried both IDE and Sata hard drives.
If I press F10 to try and start it I get this:

:confused: and I dont know what it is saving it to since there isnt any removable media except for the DVD...
thanks for your help so far
