Like it says in the Topic part I'm thinking of donating my pc to charity, but I'd like to make sure my hard drive is all clean if I do. I don't want some hacker to buy it then get a hold on whats left behind on the hard drive.... Any idea's ? Besides taking it some place to get it wiped that is... I have Windows XP SP 3 in that makes any difference, Thanks in advance

Use DBAN. (http://www.dban.org/)
Download and burn the CD/create a floppy disk.
Boot from the created disk and let it consume your hard drives ;)

Hope that helps,
Tom

I also recommend DBAN. I've used it on many donated Pc's I've helped refurbish for others

And it's freeware > http://www.dban.org/about

The next owner should have no issues installing XP or whatever, its just a clean disk for them to work with.

I would suggest removing the hdd and using a sledge hammer on it. The data may still be recoverable using spinrite.

Now thats what I'm worried about, but everyone else seems to think it'll all be cleared up.... So its a matter of who knows what...

Thanks for your input

Perr is incorrect.

DBAN prevents or thoroughly hinders all known techniques of hard disk forensic analysis.
DBAN was reviewed by the RCMP and it met their minimum standard for use by Canadian government agencies.

SpinRite was developed to recover information from damaged equipment.

Koran Yoal-You are wrong. read the website. I have recovered data on wiped and damaged drives. But then, you seem to be the expert.

I am an expert in Cryptology = 30+ years experience.

Simple hand decryption, TDM & Machine generated too.

Apparently you didn't read your own links. No where does SpinRite claim to be able to recover wiped/overwritten data. Nor can it do so.

There are some programs in Government hands that can do such, but few are available to the general public.

You may have recovered data on simple wiped [erased] and damaged drives but you've not recovered other overwritten.

Or you'd be working at or with one of the following and would know more.

The Government Communications Headquarters (GCHQ) - England

CBNRC - Communications Branch of the National Research Council - Canada

The National Security Agency/Central Security Service (NSA/CSS) - USA

WAIT - I've worked at/with all three in years past....

From DBAN:

Answer for paranoids: It's not possible to get anything back after wiping the entire disc.

Actually, IMO this is a matter of economics.

It's easy to recover the information off a hard drive that hasn't been "wiped" - little effort/cost for a decent return.
It's harder to recover the information off a hard drive that has been "wiped" - but that's a lot of effort/cost for the same return.
If the hard drive is destroyed, then nothing can be recovered.

The question then becomes "Is a bad guy willing to spend the time and money to recover your information?"
In my case, I don't have much money/credit - so recovering my stuff won't yield a decent return. So I'm not all that worried

BTW - Reinstall Windows after using DBan - that'll give it one more over-write and will make it easier for the charity.
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

As the Machine is for Charity, I would add, draining the CMOS will aid in what usasma said.

Then you can totally relax! All traces are gone!
