-I just want to point out that actually yes, PowerPC formatted external Firewire discs will boot on Intel machines. It will not work the other way around though.
+I just want to point out that actually yes, PowerPC formatted external Firewire discs will boot on Intel machines. It will not work the other way around though. (This only applies to computers running 10.4 & 10.5 This will not work with 10.6)
When a disc is formatted as what's called the Apple Partition Scheme. This is how PowerPC machines read information. Intel machines can also read Apple Partition Scheme drives.
The other format that can only be read by Intel machines is the GUID Partition scheme. When you format a disc in this way it can only be read by Intel machines ONLY. This only applies to making a bootable volume btw. If you plug in a GUID partitioned drive into a PowerPC machine it can still recognize it.
For example, I have 2 external HDDs. 1 used to diagnose PowerPC and Intel machines running OS X 10.4 & 10.5. This disc's partitions are Apple Partition Schemed.
The other external HDD I use is for newer Macs running 10.5 and 10.6. Since Snow Leopard came out stripped of any PowerPC support, this external HDD's partitions are GUID Partition Scheme.
