Has anyone read this article? (http://blogs.pcworld.co.nz/pcworld/tux-love/2009/01/dont_hammer_your_hard_drive.html) I was wondering about what it says, I use Ccleaner to clean my PC and empty the recycle bin if I have sensitive docs I want gone. I have set it to the setting DOD 3 passes.

What I want to have is some thoughts from the techs on this issue as they often do some data recovery.

:thanks:thanks:confused:

Define sensitive?
For the average joe. DBAN ought to be a decent enough program to securely wipe a hard drive for (re)sale

If I was worried about security because I sold my old PC, I'd keep the hard drive.

Well I have gotten some data from drives that have been formatted before - not always successful - but not impossible. If a drive was to go to a forensics centre, the professionals can get data back when all else fails- thats why it costs $$$$$$$ I would say Some of the programs they use are simply not available to the average computer tech.

To scan a drive for example can take a day or two.

Most average users are too lazy to use software like that, so they resort to the hammer, because they trust it more than overwriting data. IT professionals and power users obviously know this but the basic end user doesn't

Try this:
http://www.killdisk.com/

Either that or boot linux from a LiveCD and:
cat /dev/urandom > /dev/hda

Repeat 7-9x :)

I was more interested it what your thoughts were than actually completely killing a HDD. Thanks for the input

If I do not want any person recovering data then I would not give them the hard drive in any event.

Formatting a drive only stops the merely curious.

You can encrypt folders or drives which would make the data unavailable to most without a password.

It was more a rhetorical question to get peoples thoughts and I'm sure it will help people to know what actually can still be achieved with a supposedly clean drive

Open the sucker up and take to the platter with an angle grinder - once you have the platter looking decisively "dead" data recovery should be impossible.

On a more serious note, a few passes of Darik's Boot and Nuke (DBAN) should do nicely

So in other words you do not actually need help do you as you know already!

Well it's nice to have what I suspected confirmed so yes it has been helpful, I don't just go on blind faith what I read in the press I try and do some research to confirm or or not what I have read

You can use the Guttmann method which is 35 passes.

Take the drive out and get creative :rolleyes: The better half came up with this great ?? idea the other day when I was having a clean out, she saw a dismantled HDD on the bench ewwww shiny - Is it stuffed ?? - Yep - how many you got - I pointed to a box under the bench - stuffed drives - then she got that look - you know the one that you dare not ask about - next thing I know I have to find another 12-15 drives to kill - something about a "funky" set of mirrors :groan:
:help: :lol: attached is what we have so far.

My thoughts are that formatting your drive is enough for the average owner. The buyer is probably as computer savvy as the first owner and probably wouldn't even be interested.

Now a business that may want to remove possible private stuff is another matter and zeroing it should be enough.

What does the average user have that would be so tragic if someone saw it anyway? I can only think of one thing I'd rush off and report..............
