Quick question about wiping free space vs. entire drive?

Wiping Free space does not wipe existing files.
Wiping a drive will over-write everything in a partition, including all files.
It MAY do far more than that depending upon which tool is in use
I think CCleaner only wipes partitions within a Hard Disk DRIVE, and each of these is called a Drive.
I believe some tools will wipe an entire HDD, i.e. everything within partitions and also the Unallocated space between partitions.

Either Vista or 7 - I can't remember which - will overwrite sectors with zeroes if a full format is requested. I don't know if CC does this, or indeed what Windows version you have. A full format in this way, followed by a WFS will take even more time.
After all that I wouldn't believe the 5.6 days figure. We all know how variable and sometimes wildy wrong estimated times can be, for computers and plumbers. As an aside, are you using the same overwrite option (hopefully one pass) on both operations?

You seriously responded better to my question than anyone has ever answered me before ahaha! If I could get answers that concise on programming forums I would have my own OS by now, but on to the topic. Yeah I didn't know that a "full format" took that long, I always did quick format so roughly 20s-1min. I did only do 1 pass but why does it really matter how many? I mean I know that 7+ is overkill unless you're a terrorist/whatever but is there an inherently bad quality about doing so? Thanks again!
