Thanks for the input, but since this sequence began I've run the command on my SSD while booted into my boot drive...Mojave (macOS 10.14.5), so whatever reference you've found doesn't seem to be applicable.

Maybe it's applicable to fusion drives only?

I hope it's worth a few minutes of ryck's time for him to experiment.

Afterthought: That doesn't compute!

Did you mean that you've got to run a scan from a DRIVE other than your boot drive, i.e, an external (which I"ve already disproved).
