Issue: Cannot add to/delete files on external jump drives
I recently purchased an iMac M1 running macOS 10.6 Monterey, restoring my files with Time Machine.
At first my external jump drives worked as expected, allowing me to add to/delete files without issue; e.g. Music library, TV library, etc. Unfortunately and without explanation, all external jump drives are now "read-only."
I can still 'use' these jump drives as-is but cannot add to/delete files and none of the online troubleshooting found have worked. NOTE: Does Monterey NOT allow users to "Ignore ownership on this volume" anymore?
Suggestions, ideas and options are much appreciated.
