< If you cut a new thread in the plastic (self tapping screws), you
run the risk
of puting little bits of plastic on the disk.
This is something you should do in everything :)
Of course. If you don't
take care, you get lose screws....
But... Info from DEC field service (no joke, one of my 8/Ls has been
repaired for me by an original DEC field service engineer!!!) is the
following: "It's not the "big stuff" that is dangerous for the disk
system, it's everything that fits between the head and the disk surface.
Normal dust and other stuff is simply kicked away"
I use near 100% IPA to clean packs. And kitchen roll. And some force.
But I take care not to scratch packs. I got a crashed pack back to life.
After loading such a cleaned pack, I always get some "dinging" sounds
when I move the heads over the surface for the first time. But then it's
ok. I tend to clean the heads after hearing noise.
I once had a real crash. Came from foam residue entering the cartridge.
What a mess! After cleaning, the drive and pack survived the data
reliability test (3.5 hours) without any problems without any single
error. DEC's original checkout criteria allowed to have a few soft
errors during this. But there was no error at all. I'm still using both.
And I sometime run the RK05 a whole day (especially when it's cold
outside...).
(Talking about RK05, no other experience)
Best wishes,
