(It was a 3.5 years old WD, so I thought that it had to happen). Well, I was getting these errors with the previous harddrive. Now I completely reinstalled the system, and I'm getting same error messages with the new one. ad0: HARD READ ERROR blk# 25418671 ad0: DMA problem fallback to PIO mode ad0: HARD READ ERROR blk# 25418687 status=59 error=40 ad0: DMA problem fallback to PIO mode ad0: HARD READ ERROR blk# 25418687 status=59 error=40 ad0: HARD READ ERROR blk# 25418687 status=59 error=40 After these errors the box just rebooted. This looks scary. Could it be the controller? The box is an older P166, running 4.1.1-S. I don't quite believe in coinsidence of identical problems happening to successive hard drives. The new one is a very nice 13G IBM DeskStar 7200rpm, 2Mb cache. Any ideas? Many thanks, -- Arcady Genkin Don't read everything you believe.
