I'm looking at getting an external DVD RW drive for my Mac. I've already been told that my best bet is to go for one that is +/- I have a G3 400 iMac and a G3 500 iBook. Will external DVD drives work on these machines? I am looking to use it for backup, as well as possibly editing movies through iMovie (if possible) or other video editing software that may come with the drive. I have seen an Iomega drive on theirsite, but it uses USB 2.0. I am looking for a firewire drive. Does anyone know of a good one? I'm looking to spend about $250-300 Canadian (let's say $180 - 230 US, give or take). Does anyone know if it would work fine on my either of my systems, or do i need a G4? Thanks for your help.
