I have seen techs at Apple dealers use a disk they made up of a bunch of drive fixers like Norton, DiskWarrior, etc. I'm wondering if I can do the same thing and not have to take several disks when I travel? I take about 5 or 6 with me now and wonder since I own them (yes, they are registered) if there's any reason I can't do this. Any help with how to do this? Pat
