I understood from your original post that you wanted C=900gb and second partition=100, so the mystery is why that first partition is so small.
Most computer manufactures put the OS in a large partition, but I don't recommend it. I always use a smaller partition for my system drive and store my downloads on another partition. This is helpful if I want to scan for data recovery, which isn't a good idea to do on the same drive your booted from.
Additionally, I always install at least 2 operating systems, even if they are both the same, often more. If I was building my main system and had one single 1tb drive, I'd have a 100gb drive to install my main OS, a second 100gb drive for a backup copy of the OS. This way if I had a problem and didn't have time to fix it, I could just boot into the the second copy of the OS.
I also have a stripped down version of XP that I usually put in a 10gb partition at the end of the drive (the version I have will even fit in a 1gb partition if space is low).
I usually install a linux OS too, but I won't discuss that beings this is a windows forum.
The small xp version is only as a second backup which isn't necessary, and probably not even something you should consider, but thats how I like to do it. If you do install xp and vista/seven on the same computer, install xp first, because it will overwrite your vista/seven boot manager if you install it afterwards.
Another reason to keep your OS on a small partition is in case you have to reformat it, you won't have to worry about moving/backing up 900gb of files, you can just copy anything you need to keep onto your other partition/s, then format and reinstall the OS.
Edit:
A quick format wont, but a full format should do fine for the purposes discussed here.However, as far as a secure erase, reformatting will not do that,
