Hard Drive size discrepancy

[Discoduck]

x-no-archive:
I booted up from my recovery CD and deleted the current partition and
reformatted and reinstalled windows.
Normally when I do this I am at some point asked for the Windows
serial # on the bottom of my computer. But this time no.
Further more, my 80 gig HD is showing the following memory (note the
discrepancy) when I right click on the C drive.
Used Space 9,517,613,056 bytes 8.86 GB
Free space 70,530,777,088 bytes 65.6 GB
________________________________________________
Capacity 80,048,390,144 bytes 74.5 GB
(all iv'e installed is XP and Office XP).

Why the 5.5 discrepancy for capacity? That seems large, no? Keep in
mind I deleted the partition (if that is relevant).

It's the difference between how disk manufacturers and Windows define a Gb,
disk manufacturers classify a Gb as 1,000,000,000 bytes whereas Window
defines a Gb as 1,073,741,842 bytes. So 80,000,000,000 divided by
1,073,741,842 equals 74.50580596923828125Gb

That is very interesting. Had no idea, thanks.
In regards to reformatting and reinstalling XP, shouldn't the process
have asked me for my product key as well? It had previously. Any
ideas why not this time?

I would have thought it would have. What make of machine are you using?

A Compaq Presario laptop
I wonder if it had to do with deleted the partition?
