No, wait, that's SATA cables. Never mind.
Actually Eduardo it can be any cable. First observed in the 1970's at
the height of the CB radio craze, and the then Japanese dominant radios
used that color of wire for the microphones push to talk switch. I was
benching at Norfolk 2-Way Radio, a 2nd afternoon job while careing for
and feeding a uhf transmitter for the Nebraska ETV Commission and about
the time we were celebrating our 200th anniversary as a nation, I had
around 75 radios on the back shelf of the service room, waiting on
microphone cable replacements I couldn't get cuz by then nearly everyone
in the cable making business had offshored the making to the J.A.Pan co.
That was the only cable we could get thru our supply chaanels, and its
life in a large car was much less than a year. Belden finally came to
our rescue by starting up a line to make coil cord versions, but they
thought we were roping cattle with them so it took a 40 lb pull on a 2
foot cable to make it 3 feet. Complaints to the J.A.Pan src's must have
been read by employee's who spoke or read no English as it took several
years to get that fixed.
Then the same plastic die started showing up in computers at about the
same time sata became the interface std. As the outer jacket color cuz
it was purty. The actual wire inside may have a different color jacket
inside the magenta sleeve, but that only prolongs the failure to 3 to 5
years time frame.
The initial failure shows up in the logs as drive resets. So if the log
blows up when one of those colored cables is touched by a pencil, its
gone, but for a long term fix, use any other color. It will last
longer. A lot longer.
Folks laugh at me, and I guess I'm an urban legend. I'll soon be gone as
I turned 89 last week. I've done pretty good on an 8th grade education,
but I tested at IQ of 147 in the 7nth grade. quit school and went to
work fixing them new things called tv's in 1948. Got a 1st phone in
1962 and a job at the local tv station. Saw a notice in the local fish
wrap that the local Community College was testing for Certified
Electronics Technician certificates in 1972, walked into the classroom
of the prof teaching the class the next morning and put my 20 dollar
bill on his desk. Had 4 hours to do it. I was down with that years flu
so I spent some time in the john, but finished the test in 45 minutes.
Raised his eyebrows a long ways when he laid the answer stencil on my
test papers and saw a sea of black. He had been teaching that class for
several years. I, a total stranger with a $20 bill for his time, was the
first to pass that test. Not a single one of his students had passed it.
That certificate, has gotten me every job I've asked for since, its
testimony that I do know what the hell I'm doing. Yes, I have made
mistakes, and I'm honest about it when I do, but this isn't one of them.
There is one CET for every hundred EE's who can't pass it. They
haven't gotten their hands dirty enough. I've been there, and done that,
got my hands dirty and learned by doing.
Cheers, Gene Heskett.
