My question is i have a older agp graphics g4 modded a bit with a 500g internal hard drive running OSX 10.4.10 and i have just received a Mirrored door g4 with an 80g hard drive also running OSX 10.4.10. i was wondering can i just take the hard drive from the agp and place it into the mirrored door and boot that taking advantage of the larger hard drive space and not loosing my data?
