Output below.  Do you think this is an avoidable, or unavoidable error?

This is a test box, made from spare parts at zero cost.  Yep, the whole
thing was scrounged.  Beyond the annoyance of interrupting some
experiments, 100% reliability isn't the absolute top priority.  It's
there to try things out.  My other PCs are a different matter, I do
spend money on them.  I'm not adverse to partitioning around a duff part
of the drive to plod on and see how it goes.

I am amused by the statement about the device was active or idle when
the error occurred.  What else could it be?  ;-)  It sounds a lot like,
"he was breathing, just before he died..."
