tip, partition the drive into 3 C: windows/system stuff, very small, 5gb is plenty for winxp D: major programs, poser/psp/etc E: runtimes, saved pics/projects/movies/etc, library drive the reason for it split up, is programs defragment quickly ie the file parts aren't sorted as efficiently as can be so easy to defrag a drive, and keep poser a bit faster drive C and D defrag like once a week drive E is more perm files, you and poser wouldn't really be moving/editing them much, so thats why they're seperate
