20.04 - chmod not working on exfat mount

Solution 1:

And what happens when you do this:

** Unmount the partition:

sudo umount /mnt/INT-1TB-4K

** Change your mount expressions to this:

UUID=0E7E-6579 /mnt/INT-1TB-4K exfat defaults,umask=000 0 0

** Make systemd happy:

sudo systemctl daemon-reload

Remount with this:

sudo mount -a

ExFAT should have mounted 777 by default so I'm guessing your use of the "permissions" option disrupted the space-time continuum.

Hind-site is 20/20 but NTFS would have been a better choice - if you were going to use a non-linux-native filesystem.
