Hi. I own an iBook G4 with a hard-drive that has gone to H***. So I'm in the market of looking for harddrives. There are stores near me, that is no problem, but I'm pissed off at the pricing for laptop drives, compared to PC drives. My friend just bought a hard-drive, 200GB, for 160 Canadian dollars, and then put it in an external case. I was wondering if I could do that for my iBook, since it has firewire, and usb 2.0, it obviously could connect to it, if the OS was working on the laptop drive. I want to know if I could connect it to my iBook, tell the Ibook that I want that to be the boot-device, and then install the OS through the ibooks cd drive onto the external? Please say yes, because I would rather dish out 100 $CD for a 160 GB external, than $160 for an 80 GB, then add another 100 for installation from an apple tech.
