Do the external disks spin continuously?
Of course not (unless you count the fact that they follow Earth's rotation). How would a disconnected disk sitting on a shelf spin? Those aren't perpetual motion machines, after all.
Do you wonder if there is some limited lifetime on these drives?
You know the concept of backups? You know, it's not just data on internal disks that you can backup …
At least one of them outside the US, where all your tapes and backups could be seized one morning because your neighbor's uncle has a dog who humped a kid's leg. The odds of getting them back -still working- are near lottery levels, and that will cost you half your retirement. Land of the free !
We employed tape backup as a form of sneaker-net to move large (for the day) amounts of data around the country in the early 1990s. Manufacturer's claims for MTBF notwithstanding, we discovered in a very short time that triple backups were an absolute necessity if data were to be trusted to tapes. Lost data on tape was about a 1% occurrence for us, which translated to about 2 tapes a month that had to rely on their first backup, and one tape a year that had a double failure and relied on its secondary backup.

To transfer files: right-click on file, pick Copy. Unplug mouse, plug mouse into other computer. Right-click, paste.

True, but "quantum".

No. The limit on lifetime is the number of spin-ups, and you would not want the life to be too long (if you are the manufacturer).
In my experience, H/Ds unused for 5 years have about 50% failure rate too.
If you value the data long term, keep it on tape - 3 copies, in 3 different locations.
