Made it while running 10.4, booted normally from the internal drive. The copy is 10.4 (so, it was a copy of the startup disk). I used a separate administrator account because my main account is a Filevault acct.

Snow Leopard (10.6) wasn't installed at that time. After I used SuperDuper! to make the copy of 10.4, I fresh installed 10.6 onto another partition of the same external HD. I haven't installed 10.6 onto the internal yet b/c I want a solid backup first.

This was SD! 2.5, btw. Sorry I didn't mention that.

I'm happy to wipe it and make a fresh copy if it's required, but since it's so time-consuming I'd rather avoid it if there's some way I can just re-do the system files...

I think I'll just do that and let it run while I do some chores. The drive has some TurboUSB software, so maybe that's interfering with it somehow as well.
