Need help with Time Machine backups to Seagate 5TB external drive
Came home to shut-down iMac (late 2015 running OS Big Sur 11.2.3). When I restarted, Time Machine told me I cannot back up to the Seagate 5 TB hard drive (installed in Oct 2020) that I had been using; it's now read-only.
I restarted; no change.
Screenshot of Seagate drive info attached. Suggestions? Many thanks.
