USB external Pluscom drive invisible

My Pluscom drive is where I have stored a lot of precious photos which seem to have vanished from Photos. However, Pluscom won't show up on my desktop (MacBook Pro 2015 Catalina).

MacBook Pro 13", macOS 10.15

If the drive has a light, does it come on when you connect it?
Does the drive "spin up" like it ought to when you connect it? You can usually hear it, or even feel it if you gently lift and hold the drive.
Does the drive appear in Disk Utility?
Can you try it with another computer?

From help given on another thread, the solution was RESETTING THE NVRAM :

How to reset NVRAM

Shut down or restart your Mac, turn it on and immediately hold down these four keys together: Option, Command, P, and R. Keep pressing these keys for a minimum of 20 seconds. It might look like your Mac restarts.

It takes two minutes, if that, including Restart. However, two computer shops in my home town offered to sort the problem by other means costing £35 or £60 respectively. I was going to pay either of them depending on how I felt about trusting them with my data.

Thanks. I have now ticked the CDs and Connected Servers boxes but that has not helped although maybe I should go through the restart reset routine again with those boxes ticked (or "checked" as Americans say).

It lights up green, the drive is spinning but it does not appear in Disk Utility. A computer service shop tried it on another Mac a Mojave one and it was invisible.
