I KNOW the damage is done.
NEVER attempt to load a pack if you haven't inspected it AND the heads
first.
The pack was cleaned with lint-free kimwipes and 99.9% isopropyl alcohol
not too long ago.
Was this combination ever known to work?
The heads had loaded many times (with this pack) without crashing before
I connected the heads to the correct headers on the R/W module
(i.e. up->up and down->down).
You now need to throw that pack out, and thoroughly
inspect and clean the heads
and any pack to attempt to use in the future.
You also need to inspect the filter, purge the air filtration system if you haven't
done that already
along with cleaning the filtered air path in the drive
and run the spindle for a while before attempting to load the heads again.
I will check these things, thanks. The absolute filter is basically
brand new by the looks of it.
Why would the
heads be installed this way? and why did it destroy my
platter when they are connected "correctly"?
The only thing that comes to mind is the servo system is going to be extremely
confused with the embedded servo information coming in the reverse direction.
It seems to me though that the servo information was wrong
before. Please see these:

This was from TP2 on the R/W module. S2 is wrong, which is why I noticed
that up was connected to down and down to up.
Thanks,
Aaron.
