The work-around is to disable write cache enable (WCE) on the drives using "camcontrol modepage -e ...". Sorry, I don't remember the precise incantation, and you can read the camcontrol man page as well as I can. :-) Try turning off WCE on these drives and see if it fixes the problem. It can't hurt.
