Yes. Its called formatting.

i want to wipe everything, wipe as in reset every memory locations value to zero. When you format, it just deletes everything, but it doesnt reset the information in every address to zero (leaving garbage behind). and thats what i want to do

You need to do a low-level format. You can usually get a utility to do that from the manufacturer of your HDD.
Information can still be recovered from it even if you do a low-level format.

There are some tools that you can try, for example:
East-Tec Format Secure
East-Tec Eraser 2002
Sure Delete
Just search the net...
Yeah, I suppose, probably very expensive. Quite a few people have told me that the only way to make a HD non-recoverable is with gas and a matchOriginally posted by dP munky

Do a search for a little program called gwscan. It is small and slow, but it gets the job done. Start her up and come back the next day and you will have nothing but zeros on your hard drive.

There are two ways to go about it, depending on what exactly you want to do. If you want to totally wipe the drive, (prior to selling it for example) then a LLF is the way to go as has been suggested. Download the appropriate utility from your HD manufacturer's website. Be aware that this returns the drive to it's original state, unpartitioned and unformatted.
If you want only want to clear free space leaving your setup intact, (to keep anyone from recovering deleted files you don't want want them to see, for example) then use a defrag utility and check the wipe free space option. (This works for Nortons, not sure about others but it should.)
In practical terms either method will make the data unreadable for ordinary people. It is true that it you have the resources of a major country that it might be possible to read it. That's why the military, cia, etc. recommend things like multiple passes alternating ones and zeros, or even physical destruction of the drive for highly classified data.
If I want to completely wipe my HDD i just delete the files I dont want and fill up the rest of the drive with Documents full of crap. But this happens several times before it works.

if you want secure deletion, just pour acid over it, then burn it, then bury some parts of it in diferent places, others in the trash, down the toilet, and down the sink.
Did i miss anything?
The only good thing about freezing beyond feeling in the final Nordic ski race was that I couldn't feel that tumble I did going about 30 mph, maybe more.
On the other hand, not feeling any part of my body for 30 minutes was scary, especialy for my manhood.

I agree with windoze victim.
The only way to surely destroy information on a drive is to completely destroy the drive itself.
No wonder kermi3 goes through so much money... j/k

Could not you unlink (delete) all the files and then fill the drive to capacity again? repeat this a few times and the drive is not only wiped but it could bbe used again, which I think is the point of writiing zeros, obviously a boltcutter would do the trick but destroy the drive in so doing.
First, read and write the entire drive with one letter of the alphabet in every location (so you cycle 26 letters through each byte on the drive). Do this twice. That exceeds DOE standards.
Then, understand that a Hard Drive cannot be read if the reference timing marks are gone. Period. The manufacturer may have a utility to eliminate and reestablish these marks.
Eliminating these reference marks is a measure _below_ "low-level formatting". It's the ultimate in erasure, normally only done by the manufacturer when the drive is first calibrated and formatted.
Reestablish the marks and re-low-level format. Then high-level format.
