OK, I will clarify.
When you create the new C: partition, the O/S and all programs should (IMO) go on it. Programs do not have to be installed on the C: but I believe they work better when they are, since that's the basic scheme for the O/S and programs.
Data files (graphics, word files, text files, video files, audio files, pdf, etc.) have no business on the C: partition, in spite of the fact that anomalies like My Docs, My Music, My Videos are set up when Windows is installed.
IMO, ideal size for a partition with XP on it is 20GB. I have one that size on this system and I currently have 10.7GB free, with a pagefile of 2GB and no hiberfil.sys file and no System Restore running. The only program hog I have installed is Office. My system runs fine.
When you create partitions on a hard drive where there are none, you need to determine before you start...how many and how large. If I had only a 30GB hard drive, I would probably go 15/15 until I got a larger second drive.
Use the XP CD to create the partitions, once you decide what sizes you want.
Transfering files between two partitions on the same drive...will be somewhat slower than transferring files between partitions on different drives.
The basic reason I favor two partitions on the same drive (if necessary) is the fact that you have somewhat lessened your chance of being unable to access everything...if part of the hard drive or the file system (NTFS) goes awry.
