    SuperDuper didn't work either. Ugh. All the stuff looks like it transfered, but it was not bootable. I guess I have to try installing Leopard on it first. Should I take out the original HD and just leave the new one in, with the install disk running? I don't want to erase anything on HD1.

    You're sure having a time of it.... shouldn't be this hard.

     

    Is the drive formatted with APM or GPT? It must be APM to be bootable.

    In Disk Utility, under the Partition tab, create one (or more) partition(s) and then click the Option button. Make sure APM (Apple Partition Map) is selected.

    Got it!! I'll tell you what I think happened, so others reading this thread might be helped.

     

    Either one of two things probably happened: when I tried to use Carbon Copy Clone and it failed, I "erased" that boot partition in Disk Utility, but when I tried SuperDuper, that didn't work either. SO I just tried to load Leopard on the new disk, as I said I would. Turns out that it would not let me use the partition I made for the Boot Drive for Leopard either. This is surely why Super Duper didn't work. Either the first time I erased CCC corrupted the partition or it was corrupted from the getgo- I wonder if it's because I didn't use partition 1 as the boot drive. That could be it too. Anyway, once I reformatted the whole HD, I loaded Leopard, Migrated the stuff, then used Super Duper to move my media drive to the second partition. All's well and I'm not even getting any panic reports from DP when I shut down. Thanks so much.

     

    Now there's just one more thing I want to know: can I plug in my old optical and have the OWC optical firewire too? When I go to burn something, would it default to one or the other or give me a choice? I'd like to put it back in the computer, as it's convenient.

    That shouldn't be a problem.

    That will likely depend on the software used. OS X Finder services will most probably default to the internal, but I can't say for sure.

     

     

    I'm glad to hear that you fianlly got things transferred and stabilized!

    I guess you're right. I'll just have to try it out in iTunes v. Toast Titanium, etc. One thing I'm finding is that when I access apps on the new drive, it asks for the installer disk and code. Thankfully, I have everything, but it makes for more work than I thought.

     

    Thanks again, and I hope that someone upgrading Tiger to Leopard on a PCC G5 (without the ability of the stock optical drive to read the Leopard installer disk), while simultaneously consolidating everything to a new partitioned Seagate HD (with a Lynx system!) learns what they need from this thread.

    Okay, I got into Open Firmware, typed devalais and a bunch of code showed up. I don't see ud anywhere. I typed in the magic boot ud:,\\:tbxi and all I get is Can't open device or file.

     

    Thanks in advance, folks!
