I have an external drive with an HFS partition, and a FAT32 partition my dad uses. How can I prevent the FAT32 half from automatically mounting? It appears that this partition does not have a UUID
I have previously tinkered with /etc/fdisk to exclude devices from automatic mounting, but that is for devices that have UUIDs.
