I've got four drives in the G4, two of them brand-new. I'd like to do a clean install of Tiger on one of them (120gb), reinstall all apps and essentially make a clean start from scratch. The advantage to this method is that my current smallish Panther boot disk will remain as is so if anything goes wrong, I still can use the Mac exactly as it is now. Applespider mentioned to me that Mail's mailboxes can be tricky to transfer from Panther to Tiger. Are there any other things I should consider or guard against? Immensely looking forward to getting Quark activated, not.
