Hello Folks, > try to hit alt when your booting up and see if a password window comes > up Great idea. This at least gave me the choice of systems from each drive so I assume CCC did its thing and jumpers are correct. I selected the new drive, but got stuck with the pinwheel and the Mac logo from the 2nd or 3rd splash screen. Same thing after rebooting a few times... even with original HD removed and jumpers adjusted. Seems like a software issue over hardware... I gave the new HD a different name from the first; that wouldn't matter, would it? My jag CDs are a set of 2 (v10.2) but don't work as startup disks and of course I can't find my original OSX disks. Any thoughts are much appreciated. Michal
