@JeremyCherfas When I set up a Mac I make sure that all drives/volumes appear on the desktop and that they are sorted by name. That way, whichever is chosen as the boot-up drive appears in the top right corner of the desktop.
@JeremyCherfas That's mighty odd. Part of my backup routine on the Men's Shed iMac is to perform CCC & Time Machine backups to partitions on an external HD & another CCC backup to an external USB 3 SSD. When booted from the latter none of the apps try to work from the internal HD.
As for erasing the internal, can't you just select it from Disk Utility and erase it from there?
@larand Oh, you mean the feather Indians, not the dot Indians. Gotcha.

@larand It's not a proper Indian pudding without some curry in it!

In transitioning from a very dark grey car to a silver coloured on in the heat of an Australian summer, I can categorically state that when left in direct sunlight for several hours, the silver one doesn't get as hot inside & dissipates it heat quicker that the darker car. Both vehicles are hatchbacks of much the same size although the silver one's rear window is less vertical.
And at 1:25 am on Friday it's still 27℃. Later today the expected daytime hours highest temperature is 25℃ with rain. 13 hours ago it was 35℃.
@kdfrawg It all levels out at -40°. That's the only coinciding point on the ℃ & ℉ scales. So weather reports of -40 ℃ are also -40 ℉.

@JeremyCherfas Use the internal for Time Machine? I know it's a bit small for that but it does depend on how much space your boot-up drive has - I like to have 2 to 2.5 time the capacity of the boot drive allocated to Time Machine.
@JeremyCherfas Ah, gotcha. Back in the ADN days one fellow kept a 2008 iMac with a buggered internal HD operational for several years with an external Firewire 800 SSD.
I use a not-dissimilar theory with a Pismo G3 PowerBook that was given to me. An internal fault means it can't recognise and HDs in it. So I use an external Firewire 400 CompactFlash card reader with a 32 GB CF card instead.
This has the added benefit of not only being faster but larger as well. The original HD was 20 GB.
