hi, in my desperate attempt to save my powerbook g4 from demise, i've ordered as much ram as the powerbook can have, and a 250gb IDE drive. question is, when i pop the new drive in, must i format it to mac? if so, how do i do it? the attempt here is to start fresh with leopard on the powerbook. i've got the leopard retail dvd and i want to know if it's as simple as plugging the new hdd in, popping in leopard and doing an install. sounds too simple? thanks a lot! want to feel good before i take apart anything.
