Hi @Alden20,
Permissions don’t apply to an exfat partition; it’s incapable of supporting them, for Linux purposes. Try this instead in your /etc/fstab
file:
UUID=688F-6669 /home/my_user/Data exfat defaults,nofail 0 0
Some useful reference information:
- Manjaro fstab guide
- Working with additional ‘drives’
- Understanding and working with Unix filesystems and permissions
Cheers.
