tjk, thanks.
Partitioning is a thing I am not familiar with.
Boot MBP.
Connect external HD.
Open Disk Utility.
Select the external HD in the left hand pane.
Click on the Partition tab.
Under Volume Schemes, choose the number of partitions you want and the size you want each to be; you can simply drag the divider between partitions to increase/decrease one and/or another.
Down below that, click on Options.
Select GUID Partition Table.
Click OK.
Click on the Apply button.
Click on the Erase tab.
Click on Format: and select Mac OS Extended (Journaled).
Click on Erase.
Wait for the formatting to finish before quitting Disk Utility.
