I am still having "disc contact lost messages" regularly too. I've been posting about them on several occasions some time ago. I haven't been able to pinn it down, however. IF they occur, they occur somewhere between 9:15 and 9:20 a.m. OR p.m. But they don't always. This used to be 10:15, but that changed _some weeks after_ the change of daylight saving time. I can't seem to relate it to anything. It is unlikely that it's a power glitch, because the system has been displaying the problem with two different UPS's. The machine is running current current's which are regularly updated. It's an ABIT BP6 and the disk causing problems is a WD 7200 RPM 18,2 Gb disk running UDMA33. It's the only IDE disk in the system; the other disks are all SCSI. The system is running 24/7. Other details were posted earlier. There are two important aspects of the problem: 1. The problem does not always occur: it's unpredictable 2. When it occurs, I can actually hear the disk spinning down and then up again. I haven't been able to find any relevant information at www.wdc.com. I am also not sure if it is a hardware problem, however since I never noticed the problem with the wd0 driver (which I used some months ago).
