on a Rev. C iMac, a Blue & White G3, a AGP G4, and a Dual 1.25. I want to make two partitions on the drives, one UFS for Mac OS X and it's applications, and one Mac OS Extended for Classic and it's application (QuarkXPress). We are making the switch to InDesign and I will be deleting the "Classic Partition" when the switch is done. This will keep my OS X partition clean. BTW, what size should I make the Classic partition? Bad idea or good idea?
