Ok well this sort of changes things for me. I would start to suspect |
15 |
hardware...particularly any hardware that is specific to hda/hdc, and |
16 |
particularly the cables (since you mentioned "re-arranging" things). |
17 |
Remember that UDMA cables are really sensitive to length (really must |
18 |
be less than 18 inches long), and damage. |

One thing you could try is move the disks around. Linux software raid |
21 |
is pretty tolerant to those kinds of changes, so it should be safe to |
22 |
exchange hdc and hdg, for example. If the problem follows the hda |
23 |
drive to hdg, then you know you have a drive about to fail. If it now |
24 |
happens with a different drive on hda, then cable, motherboard, or RAM |
25 |
issues have to be suspected. |
