A low level disk verify reports no problems. This machine had been running non-ccd reliably previously. Am using Adaptec 2940 controller. The machine is right next to me in single user state where it stopped last week (waiting for me) and the logs show the infamous Signal 11 error which (if I am not sadly mistaken) usually means bad memory (it has been swapped) or some other motherboard type problem. Never had Signal 11 problems pre-ccd. Maybe ccd drags the i/o performance way above non-striping performance which stresses something on the motherboard ???? Wayne
