Sorry about the prior, off-list reply, DSR, I just keep forgetting to 
list reply (old age, and a brain tumor).
I don't have anywhere to put a backup at the moment except by copying 
stuff to both of these old, failing drives and praying they don't buy 
the farm until the new one arrives on Friday, so I'm using this system, 
I have no other machine, and I have work that must be done, today 
(freelancer with deadlines to meet).
Looking through dmesg, piped to less, and searching for  "error", 
"fail", or even "mount" I don't find anything seemingly any more 
relevant, as far as I can tell, than the errors I already posted above, 
unless any of this is useful (does all seem to have something to do with 
the hdds in the case, but doesn't seem to mention any errors or failures):
