Guid
 

I recently bought a new Intel iMac, still using Tiger. Naturally one of the first things I did was back it up to an external firewire drive, but I didn't have time to do a test boot.

Just now I've gone back to look at the drives, the iMac is of course, GUID, but the clone is APM. I'm assuming this will not boot? I thought SuperDuper! would make an exact clone of the original, including the GUID format.

I'm assuming I will need to format the external with Disk Utility then run SuperDuper again. But if it erases the disk won't it repartition it back to APM? Or does erasing not change that, partitioning is required to cvhange the partition map?

It'll still boot. We copy the volume -- the partition format isn't copied, since that's part of the "disk", not the selected volume.

It will boot as APM? Or if I repartition it then erase with SD?

Yes, it'll boot as APM. GUID is preferred, but APM should work.

I went ahead and re-partitioned the drive anyway and redid the clone. Booted up from the clone afterwards and everything is good.
