Ok well this sort of changes things for me. I would start to suspect hardware...particularly any hardware that is specific to hda/hdc, and particularly the cables (since you mentioned "re-arranging" things). Remember that UDMA cables are really sensitive to length (really must be less than 18 inches long), and damage. One thing you could try is move the disks around. Linux software raid is pretty tolerant to those kinds of changes, so it should be safe to exchange hdc and hdg, for example. If the problem follows the hda drive to hdg, then you know you have a drive about to fail. If it now happens with a different drive on hda, then cable, motherboard, or RAM issues have to be suspected. -Richard -- [email protected] mailing list
