You never know if you don't try. ;-) ... As far as cables, there were 6 sata drives spinning in the box (and had been for years). Six cables going toes up? I'll go with the small possibility that both from the primary controller went bad, but if swapping in the other 4 doesn't change anything, then I will be more than satisfied it isn't a cable.
The fact that two different drives were tried individually, with probably two different cables, probably confirmed that it isn't a cable problem. Still, when drive number was dropped to one at a time, were all other cables detached from mobo port connectors? Maybe with failing old cables, a single partial short or leak could be visible to other ports?
If I really think about what the probable trigger was, we are undergoing August in Texas, and we have had our hottest days they past 3 days. Sunday was 105 w/heat indexes close to 115. During the weekend the A/C raises to 85 degrees, and the server closet with its vent probably gets to 90. That little bit of added heat load/stress probably caused whatever weak component died -- to die.
Had it been shutdown more than a few minutes while the heat was elevated, with no fans running, allowing ordinarily cooler components to see extra heat soak or humidity? Slim possibility of all 6, of course. Nevertheless, never say never, and never say always. If all 6 are from an identical batch, could elevated heat have tipped them all over an edge together? Maybe not as close to zero probability as one would expect. (I'm still thinking RoHS aka lead-free solder joints, but there are parts on a mobo that are known to occasionally fail besides solder and electrolytics. Horse probably dead too.) -- "The wise are known for their understanding, and pleasant words are persuasive." Proverbs 16:21 (New Living Translation) Team OS/2 ** Reg.
