It is unlikely that both MBs would develop the same problem. You should plug both suspect boards into two of your four 2400s, but use two different internal HDs with them. The HD (that is "creating" this problem is also suspect. Leave it OUT. Then tell us if it works. I think the "bad" HD may have some idiosyncratic problem on its own, internally or possibly some flaky solder joint (higher resistance) at one of its pins. It is also possible that the I/O power board is slightly substandard. Swap it with one of your untroubled 2400s. Let us know if any of these suggestions solve your problem. > > I am now back to using the old motherboard and just using the PC slot and an > external hard drive. Try above--I feel there's a high probability that using one of the other drives after parts swap (possibly include I/O board) will clear problem. Make sure the I/O board is seated well on reinsertion into the lower case. It can loosen in its seat, raising resistance at a minimum, even if the screw is in.
