Hi Alan, After giving your subject more thought while having some food to feed my brain... and then reading Daniel's reply to the list which virtually reiterates and agrees with my comment in my email below: "NOTE: In the past, we would partition drives to organize our files. This is no longer a good idea, because there’s a performance hit in moving between different partitions."
While partitioning the boot drive still makes sense (if you needed to have two operating systems), partitioning for data storage does not. So I won't post Instructions how to "Create A New Partition" as I can see you could end up with a bad outcome... Or someone else reading this subject thread could... and I don't want to happen!
