Hi Aaron,
It's possible that this is an unrelated issue. On one of the systems with the
MPT SAS controllers, I have moved a drive from an MPT SAS channel onto an Intel
631xESB/632xESB SATA channel, and the unreliable behaviour appeared to stop.
Do you have any other drives which you can test in place of the WD drives?
Personally I have found Hitachi SATA drives to be well engineered in recent
years from a SMART PoV.
If you'd like to open another bug, the script included in this bug might help
you reproduce the problems. You could also try disabling NCQ and/or using a
different SATA controller (Silicon Image SiI 3132 based PCIe cards are
available very inexpensively) to see if this helps.
Thanks,
Tim.
