You can have a maximum of four Primary partitions on any single hard drive, or 3 Primary and 1 Extended.
You can then sub-divide the extended into logical drives (up to about 22, I think, depends on how many letters of the alphabet u got left. lol)
I have a 40bg hard drive. 2 Primary drives and 1 Extended drive which is divided into 2 logical drives.
The First primary drive I use XP 4gb NTFS and the second primary I have Win98 3gb fat32. The rest of the drive is all NTFS
I use a boot manager to switch between the two operating systems, and which ever one you go into is seen as C: drive and the other OS is not seen.
I like to experiment a lot and have made images of my OS'es so I can just re-install em as I like em, when I screw em up, lol
All my data and games etc, I like to keep on the logical drives and just a few progs on the main system drives.
Errr, hope that was useful, lol
