MBR partition table (instead of GPT) on Intel Mac okay for SD?
 

I'm using Mac OS X 10.4 on Intel hardware. The machine has an MBR partition table instead of the default partition table type, GPT, so that I can more easily run other operating systems on it.

I am able to successfully clone to another partition, but Superduper fails when it attempts to mark the other partition ("volume") as bootable.

Is Superduper compatible with MBR partition tables?

We don't really care what the partition scheme is, but OSX might. I'd need to see the error to attempt any kind of diagnosis, though.

error log
 

Here's the relevant portion:

I need the whole thing, not just a clip.

why need entire log?
 

Hmm... It's pretty long and I'd have to read the whole thing to make sure there's no personal information in there before I go posting it on the Interwebs. Is there some particular part (besides that which shows the error and associated codes, which I have already posted) that you need to see in order to diagnose?

Feel free to send it to me at the support address. But I do need the whole thing.

Where to find past logs?
 

Is it saved somewhere, or do I need to run another clone? (I closed Superduper after running it to get the error code you requested.)

Open SuperDuper!, press Cmd+L, then "Send to shirt pocket..."

entire log
 

Here it is (note that although I changed the names in the abbreviated log quoted above, I'm actually backing up from "Mac OS (backup)" to "Mac OS"):

Quite weird. So, you're updating a 10.4.8 volume with a 10.4.6 install... something weird clearly happened. Can you try an erase-then-copy rather than a Smart Update to see if that works?

Oh. Oops. No, actually I applied the 10.4.8 update to the clone partition after creating it with Superduper and receiving the same error. I just ran it again today so I could get the error code for you.

OK. But could you try an erase-then-copy to see what that does?

error log #2
 

Done.

This is quite peculiar, pmocek. It's almost like you're running on a non-Apple computer. Possible?

yes, non-stock machine for sure
 

Well, depending on how you define "non-Apple" it's beyond possible -- it's a fact. As I said before: this is not a stock machine. I have changed the partition table from GPT to MBR in order to more effectively boot multiple operating systems. GPT is fairly new, and many other operating systems don't yet handle it properly. It's a better system, in my opinion, but I'll stick with the old one if doing so will make OS X to play nicely with GNU/Linux and others.

Is Superduper restricted to use with machines using GPT partition tables when running on OS X on Intel hardware?

Truth be told, I have had trouble getting the cloned partition set as a startup disk. But I would think that if Superduper cannot do so, Shirt Pocket would prefer it to recognize this and then issue a warning, refuse to run until the option to set as startup disk is disabled, etc., instead of running all the way through the backup then failing with a cryptic error message. The latter is definitely not consistent with Superduper's otherwise excellent UI.

So, any clues? I realize this is a corner-case for now, but I'm confident that with time you'll find yourselves with more customers running OS X on newer hardware, and more of us Unix geeks jumping on the bandwagon, pushing the boundaries of OS X and Superduper in the process.
