At that age, I'd have bet that proding one of those cables with a lead pencil, anyplace in its length, would have made syslog explode with sata errors. And if a write were in progress, would have made it read only until fsck'd. I have pretty decent color vision, having in a past life, had my own chemical color darkroom for about 20 years even going so far as to formulate my own paper developer that unlike the commercial mixes of the day, would let me make 8 identical prints. That to me, is a unique shade of red with a touch of magenta thrown in. Any change in that dye's chemical makeup I would have noted, but it hasn't changed. Its still the same color it was in 1973. What happens is that the copper wire becomes a dark rust colored powder that you can cut 2" off, plastic and all and tap or shake it out over white paper, getting this as a rusty looking oxide of copper out of the plastic tube that once had the wire in it. If it is not mechanically disturbed, the ohmage rises slowly. But disturbing it mechanically breaks what little connection it has, and the syslog explodes as the kernel does its best to re-establish the connection. Replace the cable and you can bang on it till the cows come home. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
