hey.
like i try to emphasize in the guide, partitioning is a personal thing. you need to come up with a strategy that works for you.
i see no problem wit the suggestion(s) you made. i can tell you why i do it my way.
my partitioning is based (primarily) around being able to (easily) create & restore images:
http://ghost.radified.com/do you use an imaging prgm to back-up your system drive?
i prefer to keep my prgms (apps) with my o/s (on my system drive) so i only need to create (and restore, if need be) 1 image.
the Ghost guide contains a section that addresses moving your documents to another partition, so they aren't affected should you need to restore your image. see here:
http://ghost.radified.com/ghost_1a.htm .. under the heading "Effects of Image Restotation" (contributed by Christer). THis must be a good idea because I've seen other sites copy it word-for-word.
are you looking for increased performance or better organization? different people want different things. i focus on reliability. what is your primary objective? when we know that, it becomes easy to design a partitioning strategy around your goals.
for example, i don't install any *large* prgms to my system drive .. no games, no multi-CD apps, suchs as M$ Encarta encyclopedia, cuz they make my images much larger.
Did I answer your question(s)?
