[X4U] Superduper and iMac

[Michael Elliott]

Paul,

Is rhe print shop using Intel iMacs? Something else to consider is  
"What partition map was used to format the external drive?"

When you reformat a drive using Disk Utility, there is an option to  
format using Apple Partition Map (APM) vs. GUID (I think that is  
right...I don't have access to it mac right now).

Intel Macs can see/use the APM-formatted drives, but cannot boot from  
them, so they won't show up in the Startup Disk prefpane. The opposite  
is true for PPC macs. They can see/use GUID, but can't boot from it.

Hope that helps them.

Michael
