I don't seem to have it, so thank you for the followup.

Already done; no issues found. I also substituted a single stick of RAM
(8 gig) for the two I usually run. That resulted in fewer errors.

Tj, please define long? I seem to recall letting it run for about 6
hours and seeing no errors.

Nope. Stock, bog-standard except for the addition of one SATA card.

That suggests a test to try when I get a chance: power down the DVD
drive, move the boot SSD to that card and the one HD currently on that
card to the motherboard. It may be several days before I get to it,
though.
