Same problem with external HDD not recognized on my new MBP M1 macOS Big Sur 11.3.1.4 and 14TB Toshiba 3.5" drives purchased in January, formatted Mac OS Extended(Journaled), and files saved on my Mac Pro 2012 macOS Sierra 10.12.6
these drives not recognized on my MBP file manager, Disk Utility, or Chronosync app
tried on a new Terramaster D5 Thunderbolt enclosure, also on a new Insignia 2 bay HDD station
reset MBP permissions to reduced security (as described above), restarted and same issues, no drives visible on file manager, disk utility, or Chronosync.
reinstalled drives in my Mac Pro and they are recognized and work normally.
Any ideas to fix? My MBP is worthless to me if I can't read my media files
