I've got a 400/800 OWC external firewire drive that I set up some years ago with Apple Partition Map cuz I was using it then to back up both a PPC iMac and an INTEL iMac.
The old PPC iMax (ten years old) is soon to be a goner, and I'll be replacing it with a MacBook Air (and a Thunderbolt to Firewire adapter to continue use of the old external firewire drive).
So I want to erase my external and set up it with three empty partitions under GUID.
I'd appreciate help on how to do this.
I think, don't know, this should be easy:
In order: Turn on the external, activate DU and select the external drive (not any of its partitions) and click on Erase. (Is there a special erase that would check and correct the external drive for bad drive spots? Where would I find the special?) Then I click on "partition" in DU, set up my partitions, and then afterwards (not before?) select GUID. Then save all this and I'm done?
Or is it not that simple?
Thanks for help.
