As for cigarette smoke, that was somewhat of a joke.
However the heads do
have thick black streaks, probably from that damn black foam. I tried for
about 15 minutes to clean them up with chamois head swabs soaked in 99.9%
isopropyl alcohol. I'll try to spend some more time + use a wooden tongue
depressor later when I get some more time. Unfortunately the problem head
is the top head. I really wish it could be buffed with a Dremel tool.
I don't
know about this specific drive but with the top loading 2.5mb
14" Dynex and Microdata drives, we would sometimes take crashed scrap
heads and clean them up and check them a magnifying glass to see how the
heads looked, and reuse them in junk test drives.
I don't know if the drives in some of these systems that survive are
primary customer pristine systems, or perhaps have some bits and pieces
of the above type parts added. The black streaks on the heads we had
sometimes took a lot of work to clean up, but the damage was from a
crash, not from foam. And they typically worked fine. just not what
you wanted to bet your enterprise on, if you will, but fine for a test lab.
