Since this is a truncated weekend, I might just do that. If I can repair
the fault, then I will be back to a normal RAID1

I've actually done this before. If I decide to use the 2TB drives, it is
just as easy to build them fresh since my system is fully backed up.

The WD MyBook does not support 3TB. Essentially the pricing on the
MyBook is essentially the cost of 2 drives. Since I don't have much use
for the MyBook. even as a backup system at home. What I might end up
doing if I don't end up using the 2TB drives, I might configure them as
backup drives. Of course the fallacy of having backup media in the same
computer is that a lighning strike could take everything out.
