I am wondering if anyone knows how I can easily defrag a dual boot G4 running OS 9.2 and 10.2.8? I've tried starting up from a Diskwarrior CD and it doesn't work. I can boot from a system disk but I don't have an external drive to run Diskwarrior so of course it won't let me optimise the hard disk because Diskwarrior resides on the disk. Any ideas? Is Diskwarrior even capable of optimising a dual boot machine? If not what should I use? Fragmentation is up to 24% and my 40gb disk has 12gb free so I am starting to notice performance loss. I'm on a G4 Dual 533 with 896mb RAM.
