Partition table and bootability

No, I've only ever had one external connected to the system at a given time. Even if that weren't true, all the partitions have distinctive names.

I didn't know that--live and learn!

I don't know--next time I run SuperDuper, I'll check. That'll probably be this weekend. The drives live in my safe deposit box except when I'm using them.

Strikes me as the most likely scenario. This all came about because I got a WinBlows box a while back for work-related software and have been backing it up to an NTSF partition on the MBR disk. I wanted to create a Windows partition on the APM disk, and when I found I couldn't, that led to the discussion on the other forum. I was hoping to have data from both computers on both drives in case one drive died. Sounds like I'm going to have to go all-Windows on the MBR disk. or accept that I'll need to boot from the install DVD to restore from the Mac partitions on that disk.

Thanks for a good, informative explanation--really clears things up for me!
