What about DBan? Does it overwrite several times are just do the minimum?

You have a point about your statement. I do agree. All due respect to you and the other admins/staff I mentioned. No hard feelings. Just trying to get to the bottom of it all.
Now, sth else which is important. 'Ccleaner - Tools - Driver Wipe - Security' offers 1, 3, 7, and 35 passes. In terms of running the 'clean all' command - is that equivalent to running it 1, 3, 7, and 35 times or am I missing something here? The more the passes, the less likely data are to be recovered, that I do know, but the passes ... can they just be equated to running the command over and over again?

No worries. I enjoy the discussion. :)
"Clean all" and those programs both perform a "secure erase", but the programs make it easier to do multiple passes.
The more passes you do, the less chance any data can be recovered. Usually one pass is good enough to prevent the average data recovery program from being able to recover data. If you had very sensitive data, then it may be best to do several passes using a program like CCleaner or DBAN to make it easier.
Of course, the more passes, the longer it will take. This could take several days depending on how many passes.

Sure thing, but are 5 passes simply equal to running the clean all command 5 times in succession??? I am asking because I need to know how to do several passes of secure erase during the Win7 installation / language selections screen.
And yes, the discussion was pointed towards getting to the bottom of it. Did enjoy it too :_) And thanks for DBAN - looks solid.
From what I read that in that DBAN thread Brink linked to, it seem that DBAN definitely can do more than 1 pass, which is really good.

Running "clean all" five times in a row would essentially be the same as running five passes. It'll take a while to finish that many though.

I'm wiping a Vista machine a friend gave me, and I'll be installing Win 7 on it. I don't see any malware on it. Will the Win 7 disk's wipe be good enough? I can't use Diskpart on the same HD I'm wiping. Or can I?

Because it's a friends old computer, you don't know what is on the drive.
If it was my computer I would do a Clean All or a 3rd party disk wipe program. One pass of the entire drive should be enough.

Personally I don't see much difference if any between a clean, clean all, or a wipe it does basically the same thing and as I sort of pointed out with the chalkboard analogy.
There are plenty of drive cleaners/wipers whatever you like to call them and all I am saying is that a lot of people just format and then usually end up back here wondering why their clean install is not quite right or the drive is balking at installing at all because as I said because I know that Windows will format the drive on installing itself onto the cleaned drive. Plus it takes no longer to clean a drive than to simply format it and I think that formatting is best left for preparing a drive of any sort for use after it has been cleaned or individual partitions on a drive.
Now the only reason that I will clean all a drive is when I am going to give one away to someone else but as Brink and Jack have said it does take a great deal longer time to do that - having said that it depends on the size of the drive of course.
I agree though that debates like this are
