Following this thread to its logical conclusion:
What would happen if I inadvertently attempted to boot an Intel based clone on a PowerPC system, or vice versa? Not sure how this would be possible. The incompatible clone would not show up in the Startup Disk panel, nor show up as an option on a reboot (depressing the option key). However this happens (like to hear the possible scenarios), would OS X create an error message, show a spinning wheel, or crash, thereby corrupting the clone? |
It'll most definitely crash. Whether it'll corrupt the disk, I don't know...
|
So, under what scenario could you even attempt an inadvertent boot to an Intel or PPC clone? It seems the disk would not be recognized. Or am I missing something here?
|
It's unlikely, of course. It's hard to imagine how it would happen... but if there's a way to do it, I wouldn't recommend trying. :-)
(I'm certain, for example, you could restore a PPC volume to an internal drive on an Intel mac. But don't.) |
For a variation on the above questions my wife and I both have Powerbooks which I used to backup by closing to a single drive with two partitions. I have just bought a MacBook which is of course Intel Mac. Can I just run SD on Smart Backup to the same partition or do I need to erase and start again on that partition. If I have to erase do I need to reformat with the Disk Copy on the Intel Mac or does SD handle that?
I am assuming from all the above discussions that I will end up with one partition that can boot my wifes PB and another that can boot my MB. Very nice! Thanks - Michael |
If there's enough headroom for SuperDuper! to make the copy, it's no problem to use Smart Update on the drive, no matter what was on it before.
And, yes: as long as the external drive is partitioned with APM (Apple Partition Map), it should work fine with both machines. |
