Hi, New to the Mac forums but being using Macs for more than a year. I recently replaced/upgraded my MacMini's HD due hardware failure. It was still working but about to die. So I had the chance of cloning the HD before replacing. I put a 1GB hybrid HD. But Time Machine immediately triggered a FULL backup instead of a Differential, as it usual does, and filled my external USB backup drive. How can I force or make Time Machine to continue running DIFF instead? I guess that Time Machine detected it as a new HD and that's the reason why it insists in a FULL. Any help is highly appreciated.
