Wd Elements Not Mounting Mac Hard Drive
Before upgrading to Big Sur, I did the typical system backup and all was fine.
After upgrading to Big Sur, connecting my Time Machine (TM) WD external disk (via USB C) results in a 'read-only' mount and TM refuses to repair the disk or backup. I have tried ejecting and reconnecting, Disk Utility First Air, and booting up in Recovery Mode (at Apple Support's suggestion) with no luck.
Wd Elements Will Not Mount
The drive is visible after mounting in 'read-only' and accessible, so I don't believe the drive is the issue. It is Mac Extended Journaled and Encrypted, but nothing special otherwise. Other WD external drives for media and content, similarly setup, all mount fine in read/write.
