Now your asking, not sure. Can only recall extended journaled as an option. For example this morning using the disk utility I did a restore of my 10.5.6 dmg image onto one of the drives, expecting that to be enough. I'm pretty sure thats all I had to do with the sorbet I put on my other recently acquired powerbook (1.67 g4). As I say, still new at this and if I'm missing something in the format process, I'd welcome any pointers.
Go ahead and pop open Disk Utility once more, select the physical drive associated with those two FireWire volumes, and see what shows up below. It ought to look something like this (emphasis on “
Partition Map Scheme”):
If
Partition Map Scheme shows something like “Master Boot Record” or “GUID Partition Table”, but not “Apple Partition Map”, then your PowerPC Mac,
even if those two FireWire volumes have a version of Mac OS X on them, will generally not be able to boot from them. (There are noteworthy exceptions to this rule, but it’s generally a rule for good reason: a handful of PowerPC Macs are able to boot from a different partition map scheme, but
all PowerPC Macs are able to boot OS X from a “Apple Partition Map” volume.)
You’ll want that FireWire drive (the disk itself, not the two volumes on it) to have an “Apple Partition Map”, or APM for short.
If you need to do that, then you will first need to re-partition your FireWire drive as “Apple Partition Map” and decide on how many volume partitions you’d like to have for it.
Under Disk Utility’s “Partitions” tab, you can select the “Options…” button, after deciding on how many partitions you’d like, to select the Partition Map Scheme. Select “Apple Partition Map (APM)”. Run the partition/format step next. Now, you can mirror or install OS X onto the FireWire volume(s), and the Mac you have should be able to boot from it, as well.
Doing the above, however, will delete all the data from that FireWire drive, so if there’s any data on there you’d like to keep, make a backup of those first.
