A fairly exhaustive test run on the old disk drive with its new Dysan pack gives it a clean bill of health. The pack is absolutely clean, and the drive behaved itself through nearly 2 hours of diagnostics. It glitched only once, which was almost certainly static electricity -- I was replacing the top on the cpu box at the time, and the timing of the message was precisely right. Unfortunately, we've also had a sharp upswing in the soft error rate on the new drive. This started quite abruptly late this evening. I will take a closer look at this tomorrow; until then, I have turned the driver's "patient" mode back on (and set /etc/rc to do likewise). The errors are all very soft (one retry gets rid of them), they are all header ECCs, and there is no consistent pattern on head numbers. I am beginning to get impatient to get the new controller running. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
