So the fact that mine does work most of the time, the failures I
do see don't require any resetting of the device and don't
involve log messages about the device, plus my having the
same srcversion as you, all point to that not being the
cause of my problem I'd guess. Although I have still
to try uping the latency from 32 to 64.

Too early to say. No problems yet. It is exactly the same
model drive, so the only difference is I have it as a
single partition, rather than 2. I must remember in
the future to use a range of makes when I buy HDDs, so
that when problems occur I can use swapping as a way to
track the problem down.
