I've also experienced this with plain USB block devices like some of my
microSD adapters.  No idea what causes it.  Sometimes it shows up in
Nautilus for a split second and then disappears.
Weirdly enough, running fdisk -l on the block device makes it show up in
Nautilus.

But it should be noted that our Nautilus version is behind by two versions.
