Sounds like a failed drive.
Here's an article I found that has the sounds different kinds of HDD
failures make:
https://tierradatarecovery.co.uk/the-sounds-made-by-failed-hard-drives-and-what-they-mean-for-hard-drive-recovery/
If the drive still spins but can't be read, it could be failed
electronics in the case or a failed circuit board on the drive itself.
I have heard of drives being "restored" by replacing the circuit boards.
I wouldn't trust it for continued use, but it "might" work for long
enough to let you rescue your photos.
The info I find on the internet is mixed. Some sites suggest it can work.
Some sites suggest it can work if you swap the BIOS from your existing
drive to the new PCB, and some sites suggest it won't work at all.
A data recovery site might be your only hope.

Cotty,
Sorry this isn't clear. There are 3 external drives in our little
drama: Backup (Time Machine), New, and Photo.
The Mac Mini isn't showing the icons for =any= drives. (The System
Report knows they're there, though).
My venerable MacBook Pro recognizes all three, opens Backup and New,
but can't open Photo.

Two external drives are now connected to my MBP, and are working
normally. The photo drive shows up on my MBP, but won't open, and
Disk Utility tells me (in red) that it can't be un-mounted in
order to be repaired.
In the above para, you mention that the two ext droves are
connected to you MBP, and 'are working normally'.
Yet the photo drive won't open. You don't mention the status of
your other drive (presumable the drive you use for Time Machine?).
Is this second drive working normally? Define 'normal' please :-)
The thing that needs to be ascertained is if the failure is
hardware or software. Points towards a failure of some kind on your
photo drive, but can you confirm that your other drive operates as
intended when connected to your MBP please?
