For the disk partitions permanently installed in a linux box, I have, of course, fstab.

For plugged in USB drives, I rely on udiskie, an automounter for udisks.

When I’m looking for plugged in partitions, I use these two:

doas blkid -o list  # shows fs_type
lsblk -f

Of course I sometimes need to # umount /dev/sdx or # mount /dev/sdx, and # chown -R jo:jo /run/media/jo/<drive>.

For the dastardly NTFS partitions that I use for easier sharing between operating systems, I’ve NTFS-3G.

For my digital camera, gPhoto gets its storage partition visible in PCMan File Manager.
