A few months ago I got a mac pro to replace my old G4 Quicksilver (it was upgraded to 2Ghz). I am used to regular maintenance with DiskWarrior but my understanding is that you cannot use Diskwarrior as a start up disk with the Mac Pro. What would you suggest for regular maintenance? I already have Onyx and Drive Genius 2 should arrive this week. I have two Hard Drives for Leopard and one for Windows XP.
