My G5 tower is running its original 160GB + a 300GB drive in the 2nd bay. The 300 is partitioned to hold a clone of the main drive + extra files in the 2nd partition. Cloning is done regularily with SuperDuper. Today I ordered a 750GB drive. My plan is to switch out the 160 for the 300, use the clone as the system drive, and install the 750 as drive #2. I am still running 10.4.10. Should I anticipate any problems with this procedure? Many thanks, Carter
