If I plug in the USB drive the mount command adds a line:

/dev/sdd1 on /media/jjj/128GB type ext4
	(rw,nosuid,nodev,uhelper=udisks2)

And the drive works perfectly.

However, at this point the optical drive won't mount anything. I tried
half a dozen different DVDs, the light on the drive flashes briefly,
then stops. The mount command does not see it, nor is there anything in
the GUI file manager.

Now I'm worried that there might be a hardware failure.
