It was not with this same controller, however it was not the controllers fault. Random disks will drop and reattach. For me, this was power supply problem and both times replacement fixed the issue. If you haven't checked into the power supply. I would suggest testing it. Especially If it was previously working fine. On Fri, Jul 29, 2016 at 9:41 AM, Eugene M.
