I am planning to move from Panther to Tiger on my G4 Tower (AGP Graphics) and am thinking it would be a good idea to partition the 80 GB drive at the same time. Questions: 1. Does each partition have to have a copy of Tiger on it in order to function? 2. As I understand it, I can use a program like SuperDuper or Carbon Copy Cloner to make a bootable clone on one partition. This clone can then be used if my main partition fails. As I also understand it, I should not store anything else on the bootable clone because it may cause the backup software not to work properly. Do you agree with these points? 3. I read somewhere it's a good idea to have three partitions, but I don't know why. Can anyone enlighten me as to what the third partition would be used for? Please advise. Thanks.
