External Hard Drives Won't Erase After Using With Time Machine

Hi,


I have 2 external hard drives that I was using for Time Machine. I have now replaced them and want to erase them for use as normal drives. I have de-selected them for use with Time Machine but Disk Utility won't erase them. It can't run First Aid on them either. It looks like they have become read only.


Here's the error message if that helps:


Erasing “Seagate Plus Drive 1” (disk11s1) and creating “Seagate Plus Drive 1”


Framework unable to communicate with the Disk Management daemon. : (-69812)


Operation failed…



Any ideas on how I can rescue these drives?


Thanks in advance!

MacBook Pro 16″, macOS 13.2
