When I originally partitioned this XHD years ago, I made 2 partitions for Mac & one for Windows. I only have First Aid, Erase, RAID & Restore tabs. When I select that volume wi DU, I do not have a tab for Partition. I tried to check if my XHD volume (It is partitioned into 3) is GUID. I searched Google for how to reformat a volume. The one feature of CCC & SD that I know I’d like is update (replace only things that have changed since the last clone) which will shorten the time to clone. If I knew that Time machine would have priority & CCC would wait till TM was finished b4 beginning its scheduled clone, it would be nice. Not sure I would use the scheduler feature of CCC or SD to create regular clone backups since I will have Time Machine volume backing up every hour automatically & not sure about possible conflicts between the 2 tasks that may try to run at the same time. I’m not sure I need the recovery HD backed up since I clone in order to be able to restore my system in the event of a failure or loss of my Mac HD. I knew that CCC backs up the recovery HD & SD does not. Try the DU Restore again from your Recovery HD. Try reformatting your external drive from DU and click the Options button to ensure you have the GUID partition map selected then click Apply. The error you're getting appears to be due to your external HDD not being setup with the GUID partition map. For example, they both have schedulers, have the ability to update your clone after the initial create instead of 'erase and build', CCC backs up the Recovery HD and has a feature to recreate it from CCC via Disk Center. To answer your second question, first, CCC and SD have other features built in that DU Restore doesn't.

Both are formatted Max OS Extended (Journaled)Īlso, what advantages, if any, are there in using CCC or SD instead of the free DU? I launched DU from recovery system, selected Mac HD as source & my XHD as destination. “Restore Failure, Recovery partition restores can only be done on GPT partition maps.” Tried to create a bootable clone using Disk Utility & got this:
