The above method will not prevent somebody that knows what they are doing from recoverying data from your machine.

Right.
Any suggestions on that?
Never had to wipe a drive to get rid of anything that sensitive, but i'd like to know how just in case the need ever arose.

So I'm curious about this (as I have heard many people say things like this).
After a format like this, how the hell could anything be recovered? I mean, I've heard the somehow, bits of data can be used to "reconstruct" the contents, but where are those little bits of data stored?
For instance, if I completely fill a HD with sensitive material, then formatted, then re-filled it, how could it still have traces of anything "sensitive"?
A computer cannot possibly keep a log of every single item ever stored on it, so what gives?

There are several threads in this forum that discuss securely erasing data from your hard drive. I don't use windows, so I have no idea what programs do this. The method mentioned above will overwrite the start of the disk, but marks the space at the end of the disk as free rather than actually erasing it. With the proper tools, a person can read that data.

I take it you want to wipe your disk for security reasons? Ok, simple stuff. Go to www.ultimatebootcd.com, download the ISO and burn it. Pop it in the drive and reboot. You will then be looking at a huge variety of system utilities which you will find useful on many occasions.
The tool you want is called "Darik's Boot and Nuke." I think it's under Filesystem tools, but may be under Hard Disk tools. This will overwrite every bit randomly several times, to prevent any data recovery. The quick option takes a couple hours and does a good enough job, the more thorough options take quite a bit longer.

I have a zero fill tool for hard drives. Usually when you delete files or format it will just erase the first number in the files and make it a zero. then the rest of the data from files is still there. the zero fill tool wipes out everything and makes the drive look like a brand new drive.
mine shipped with hard drive but I am sure if you do a search you can get one.

EVen after zero formatting data can be recovered due to the way the magnetic medium stores data, I for one don't know the exact physics behind it but it can be, although chances are you are not going to be targeted where that kind of money will be spent on you so just zero fill.

Darik's boot and Nuke is awesome. Available free, and is packagaed with many pay products. http://dban.sourceforge.net/
It has many options, zero fill, random # generation, and can do multiple passes on many of the methods.
