PS: ATTENTION!: How do I Automount an Hard dRive in my Computer in Ubuntu?

[Ralf Mardorf]

PS: I know what I'm doing, so I'm using /dev, but in general it's not
wise to use /dev. If you don't know what you're doing use UUID instead.

It is really stupid to not read how to use fstab and just to copy from
mtab to fstab.

I recommend to visit https://startpage.com and to use the search term
  why uuid instead of dev
or similar ;).

Or again, just read how to use fstab.
