Need help on erasing hard drive

Hello all. My computer has been having a lot of problems lately and I was thinking about using DBAN to start over again. I've used DBAN a lot of times, but for one pass takes about 5-6 hours. I was wondering if any of you have any suggestions on something other than DBAN. I know DBAN may not be the problem for it being slow, but I would just like to know if you think there are any better programs than DBAN. How many passes would you recommend me doing? I am not planning on selling it or doing anything with it, I just don't want files leftover. Thanks!

There is no performance reason to wipe the HD with any more than the quick Diskpart Clean command, which zeroes the boot sector that sometimes can have corrupt code interfering with WIn7 install or booting.

Any more than that - using Diskpart Clean All which writes zeroes to the entire drive, DBAN or the others - only serves to destroy data so that it is unrecoverable by normal methods but not forensics, nothing else. There are always going to be either ones or zeroes there, so forget the whole idea of "erasing" anything.

It took awhile for this to sink in for me: You gain ZERO performance advantage by zeroing the HD. Win7 doesn't know the overwritten code is there any more when it overwrites it itself during daily use, than if it has been already overwritten with zeroes.

So Diskpart Clean Command is sufficient: SSD - HDD Optimize for Windows Reinstallation

More important are the steps you follow to assure a perfect reinstall, not wiping or "formatting" the HD as though that describes something really extra special clean.

+1 to DISKPART - CLEAN ALL. One of the most under-rated tools in our arsenal.

Disk - Clean and Clean All with Diskpart Command

again!

My personal choice would be to use the MS formatting function provided through Control Panel. Consider the following:

Again, that's a personal preference over the use of a utility. Life is nothing but a series of decisions.

Using CCleaner or a plain format is all good and well, but Diskpart is the easiest way.

With the other methods, you're just wiping existing partitions clean, and you can only format/wipe those that aren't in use by the system anyway.

Running Diskpart from the Windows setup DVD circumvents all these issues and ensures a complete disk wipe, no ifs or buts.
