Can't find old HDD

[Monkeyman]

I am posting from my Chromebook right now. So I cannot post pictures on how my thunar preferences are set.
Under advanced settings.
Volume Management.
Configure.
Maybe poke around in there.

So

Code:

/dev/sdf

is the external enclosure.
Funny that blkid does not show it.
Funny that thunar does not automount it.

Since the command line "cd" is and "ls" is giving no joy.
Just open thunar and look in media and hopefully a folder saying sdf is in there?

Nope.  Nothing.  If I type "/dev/sdf" in Terminal, I get "Permission Denied".

Now that I think about it (and it may not make any difference), this has been run on both Ubuntu and Windows.  I wonder if something could have become corrupted as I swapped systems?  Maybe that doesn't even matter as the rest of the HDDs have been run under both OSs.
