That all worked beautifully. Right up until I left the BackupPC running

It failed again after about 30 hours. The symptoms are the same.

Ah, well.  "Smart" can't catch everything.  Do consider that you might
have some other hardware problem, though.  Power supply, data cable, etc.

I think I need to bring the array back up but leave that disk offline with:

mdadm --assemble --force /dev/md0 /dev/sdb /dev/sdc

(sdd is the bad drive)

Then follow the remainder of the steps to check.

Don't bother with another check run.  It is only meaningfull if you have
all three drives.

I have a new disk on the way. I would then add this new disk into the
array and sync.

Yes.

Does that sound correct?

Yes.
