You may be right since the problem seems to occur only when I'm doing heavy i/o on the disk. However, it's unlikely to be a cabling problem as I did try two other cables, but to no avail. FWIW, I'm using a SCA device with an adapter that is supposed to provide active termination... I'm not sure how to verify if this is a termination problem. Any suggestions?
