Installing hard drive to Mac Pro

Those are the proper settings. Should be fine now.

 

What partition scheme did you chose? GUID, Apple or MBR?

GUID is usually recommended for Intel Macs and I always use this. It used to be the case that it had to be GUID to be bootable but I think there are exceptions to this.

In Disk Utility, you can tell which you have currently selecting the hard drive on the LHS (not the indented volume line) and looking at the bottom of the window where it says "Partition Map Scheme:"

To change it you chose the partition tab, select the number of patitions you want (which will be one if you don't want to partition) then click the options button to bring up the choices. This will reformat the drive again.

 

So then is GUID better/faster on a MacPro? If so I think I've messed up big time with my four drives. I read GUID was important for Time Machine on an external drive, but I didn't figure this out for the internal drives.

 

I don't think better or faster comes into it, but you may not be able to boot from a drive which is not GUID. If you only want to use the drives for data you should be fine with the Apple Partition scheme (which I assume is what you have).

As a general rule:

Use GUID for Intel Mac OSX
Use Apple Partition for PPC Mac OS
Use MBR for Windows

This is what Apple recommends. YMMV.
