I partition my hard drives. I have 7 on 3 hard drives. I don't use system restore on any drive but C. I have my pagefile on it's own partition. (the first 3 gigs on a 160 gig sata hard). I don't need to defrag
I know you all will oppose to this, but when I do defrag in this setup it doesn't move anything but a couple of files on my C drive. I never experience a speed loss either. Now I do, do a disc cleanup for my temp files though for obvious reasons
My set up
1 50 gig WD. 3 partitions (2C and a G). 2 20 and 1 10 gig (Dual boot OS, 1 Game Drive)
1 200 gig Maxtor. 2 partitions(L and M). 2 94.5 gigs (My Documents, My Movies)
1 160 gig seagate sata. 2 partitions(S and X). 1 3gig and 1 146 (Swap File and Xtra)
I just don't have a reason to do it
