Paul: I'm not sue why the second internal drive isn't showing up as GUID partitioned in System Profiler. I just checked and mine all do, so it may be that the drive didn't get partitioned as GUID after all. I use Disk Utility, select the drive to repartition, select Partition, change from current partition to 1 Partition, and then go to the Options... button and select GUID. and finally, Apply.
