I realize PPC Macs need to use the Apple Partition scheme and Intel Macs the GUID one.
What happened is that I did a backup using CCC from an Intel Mini to an external FW800 drive.
The external had two partitions on it already, one was used for general storage, the other as a short term temporary backup.
The partition scheme on the external was the Apple one and I don't think I could have changed that just for the one partition I wanted to use for the backup without repartitioning the other section used for general storage which was pretty full.
So I cloned the Mini to the external section with the Apple partition scheme with the understanding (from a CC message) that the Mini may not boot from the backup.
If it hadn't booted using the backup I would have bought another drive, formatted it and backed up to that, but it did boot fine and I have been using the back up for a few days now.
So now I have the Mini internal hard drive (GUID) with data that is a few days old and the external (Apple partition) which is up-to-date as far as email etc. are concerned.
The Mini btw runs much faster on the external - I assume that either the internal had become quite fragmented over the years or there is actually a hardware problem.
I now want to erase the Mini internal drive and clone back from the external to see if that improves the Mini performance with its internal drive.
Question - Anyone know if I'm going to run into problems with booting from the Mini or otherwise since I will be cloning from a drive with the Apple partition scheme back to the GUID partition scheme?
Other option is to back up the Mini to an external drive I just bought which will be partitioned GUID and then clone back from that to the Mini; this would mean I need to recover the few days of emails, data etc.that won't be on the Mini since I did the backup.
Doable but a bit of a pain.
