Thirty years ago I used to know how to use mount and
/etc/fstab and things like that to mount disk drives. But nowdays, it’s all too hard to remember. Especially now that we use UUIDs.
So here are some things to remember:
$ lsblk # a very pretty way to see block devices (like lsusb for usb devices)
$ sudo e2label /dev/sdb1 # to see what I called the device
