Thank you.
Maybe this was a dumb question.
I am still getting used to the El Capitan and its new Disk Utility application.
These questions came up because I was following Apple's old instructions on moving one Time Machine backup from one drive and volume to a new larger drive and volume. I understand that most of the time we use OS Extended volumes with Journaling. GUID partition maps are the norm since Power PC was dropped and Intel processors adapted.
However, I was unfamiliar with the new Disk Utility application.
When I selected the volume and not the drive, I missed the text under the name of the volume. The table underneath the name of the volume had little information within it that was relevant to what I did not already know. I knew the size information and that it was a USB connected drive.
Bottom line - I did not know for sure how the original drive was formatted by the manufacturer and wanted to be sure before wasting a day or two copying over my 2 TB time machine folder.
Had I been more awake last night at midnight I might have been smarter and selected the drive under Disk Utility and not the volume before asking the question. The table under the drive indicates a line "Partition Map: GUID Partition Map". Had I been smarter, I would have seen that but did not.
What I really wanted to get across was that this information is more spread out in the new Disk Utility application than I seem to recall with the older Disk Utility application. With the old application, I used to be able to see it all on the same screen.
If new MAC users add an external TM Drive or have the same questions about the new Disk Utility application, hopefully the information from this conversation will help them to find it.
