Is Disk Utility the way?

Have a  external FW drive that has been used to backup tiger 10.4.11 macmini

Without reformating it  I cloned (with CCC) a different computer using SL 10.6.8

While it showed up on the screen on restart with the option key down

it would NOT boot.

Eventually it's icon showed on screen as a FW drive,

but on selecting it to eject it, it would not eject.

 

So assume it's PPC setup is incompatable.

Can I just overwrite with DU? or is there something special since it was PowerPC?

Purpose is to have a bootable clone without using Time Machine on it, but Carbon Copy Cloner

Mac mini, Mac OS X (10.6.8), 1.83 GHz Intel Core Duo 2GB

    I never use bus-powered externals, except the keyboard and mouse, but I suspect that trying that is straining the throuhput.

    You might have to completely erase and reformat one of those, using the GUID scheme and try again. For further queries, you might want to try the CCC forums.

    PowerPC Macs use the Apple Partition Map and Intel Macs use the GUID scheme. It doesn't really relate to OSX 10.4 because it came in two versions and could run on both PowerPC and Intel hardware.

     

    I suspect that you're using the wrong partitioning scheme for the intended Mac.

    Note that both screenshots are showing the same thing, since when you select the disk, not volume, you verify or repair all mounted volumes. When you do that on a volume only that one's looked at. Since you only have one, they're the same. Also note, that repairing permissions won't make volumes bootable. Check out http://help.bombich.com/kb/troubleshooting/what-makes-a-volume-bootable and http://help.bombich.com/kb/advanced-strategies/help-my-clone-wont-boot. FWIW, all six ext powered FWHDs boot with CCC clones containing Snow Leopard, Lion, or Mtn Lion.

    Are you trying to boot a PowerPC MacMini from a Snow Leopard formatted disc? If so, that won't work.
