If you use this program i mentioned you do not have to worry about anything. It is free and will clean all remnants of files and is just as easy and fast as any other utility.

Use the utility FDISK
Start by using a startup disk

The question is how clean do you want the HDD to be?

And, how critical, confidential, sensitive is the data on the drive?

If the data is very confidential and sensitive to the point where someone would be willing to spend a lot of money to getthe data, then you need to destroy the HDD platters.

Otherwise, in order of security level:

DOS boot, format c: /u

Startup disk boot, fdisk: delete ALL logical drives and partitions.
Re-boot, fdisk, create new partitions of a different size.
Format all drives.

Delete all partitions,
Create new partitions,
Format the drive
Run one of the security rated drive over-write programs.

The more you do, the harder it is for someone to recover the data.

Consider what the value of the data is versus the used value of the hard drive.
If you dis-assemble the drive and melt down the platters, the data is definitely not recoverable.

Guess it depends on how paranoid you want to be....

The Department of Defense has a policy (DoD 5220.22-M is what it is listed under) that to truly erase data from a hard drive, you need to run an application that will do the following:

1) delete the files to be removed by normal operating system method
2) overwrite the sectors on the disk that the file was written to 1 time with the Hex value "0x00"
3) THEN overwrite the same sectors on the disk that the file was written to 1 time with the Hex value "0xFF"
4) THEN overwrite the sectors on the disk AGAIN that the file was written to 1 time with a random Hex value
5) LASTLY, perform steps 2-4 a total of 6 more times, one after the other.

Only after that is the data considereddeleted. They do not consider doing an FDISK as being foolproof enough. Apparently, you can still recover data after doing a FDISK.

Now, Norton Utilities 2002 has a feature called Wipe Info that does just this DoD thing. It takes a long time to wipe everything away, but it can. ****, this app will even let you set the total wipe times (of doing the whole DoD thing) up to 99 times (for those who are just crazy paranoid!!!)

You could look into getting Norton Utilities, and run Wipe Info.hope this helps

the part of the HDD that contains the root structure of the platters is called the MBR (master boot record). Fdisk doesnt touch this portion of the HDD and it can contain information about the drive that can reveal the info that was on the drive prior to an fdisk, or the parameters of the drive befor the last fdisk. There is a file available for free called ZAP.exe you can search for it or email me and I will send you a copy, I keep it on a win98 boot disk so that I can always start fresh when I load or reload win98. This file doesnt erase the data in the MBR, or reformat it. It is more powerfull than that....it writes zeros to the entire MBR. When you format the disk it will rebuild the MBR automaticaly. (this is also a way to fix fatal error messages that cannot be fixed any other way)
