Hey All, I bought a new core duo mac mini. I replaced the stock drive with a 7200 rpm drive. When I first booted it of the install disc it could not see any drives. So I booted the drive in target mode and hooked it up to my powermac. I used disc utility to format the drive to hfs+ (journaled) and I can see the drive now when I try to install OS X on it but it has a red exclamation point and says it cannot install OSX. Any ideas?
