Is there something wrong with my way of thinking about data and content?
PS: I am running OS Tiger.
I don't think there's anything wrong, but personally I would do it another way. Being that you know how to copy the contents of your internal drive to a Firewire drive, I would temporarily put the new drive in the external enclosure, copying the data to that disc before putting any tools to my powerbook. Once I'm confident that Ive got two copies of my critical data, then I would switch the drives.
This might be a little paranoid, but whenever getting into a machine like that I like to go as slow and steady as possible.
If you aren't already maxed out, it's an ideal time to upgrade your RAM, which is certainly cheaper now then when you bought the G4.
I would also strongly suggest whenever you put your fingers or tools into your computer that you carefully ground yourself first to avoid static discharge, which can lead to very strange and impossible to solve performance problems down the road. (You probably know that but it's always worth restating in my book!)
