I'm new to the iMac G4/800 and would like opinions re pros and cons of the available disk diagnostic utilities: Norton SystemWorks, Micromat Drive10, Alsoft Disk Warrior, and others possibly. I've heard of problems with SystemWorks, Drive10 does not optimize, and although Disk Warrior optimizes I know little or nothing about it. Most of these if not all as I understand it boot using OS 9, not OS X. Right now, all I have to use is Apple's Disk First Aid which doesn't offer much help beyond minor fixes. How is the upcoming "Jaguar" version of the OS going to make these obsolete?
