- 2017 27" 5K 1 TB ssd OS = Monterey 12.6.1
I have an external HDD ( 6TB ) that I ran Disk Utility first aid on. it failed.
It ran ok on the VOLUME but when it ran on the DISK it failed.
The drive looks different to others that I have as it shows that it is Mac OS Extended ( Journaled ) which is the same as other HDDs. However the partition map is showing as MASTER BOOT RECORD.
All the other external disks that I have are Mac OS Extended (Journaled) with GUID partition map.
Is it the different partition map ( Master Boot Record ) that is making the first aid fail?
I am wondering if I format the disk with Mac OS Extended and GUID partition map and then copy the files back to it from another HDD using Carbon Copy Cloner will it then pass the first aid?
The HDDs are kept for archival purpose mainly for photographic files.
The error message gives a Disk Management error code which shows in the attached screenshot.
Cheers
