FAILURE!
Hi mediaman,
Just to double check the head and your skill, put it back to its original place and align it.
If it worked then your H swap was perfect. Look for possibility of incompatible head assembly,
bad PCB or F/W problem.
If it didn't work, conclusion is there...
I have done HS on this model 3 times. One complete fail. Other two partial success.
In one case I had to disable a head to clone the drive. In another case cloned with
tons of bad sectors.

Hey PNINJA, thanks. Yes the reverse swap did sound like a nice learning idea and I was going to go for it but real work got in the way. I now realize that only one repair station (Atola Insigt + Server) at a time is very slow way to handle several disks. I concluded that the alignment issue would not make it worth the try.
Have you really managed workable HSA swaps on 2 out of 3 WD75000AAKS? Did you just bolt them up and they worked? No lid tweaking? Do tell.PM fine. In your head disable case, did you use Deepspar head mapping feature to do that? Insight does NOT support head control

Thanks again for the positive feedback!
I don't have Insight tools. I use my home made tools plus ACE lab and Salvation data.
However I found your words "Have you really managed..." insulting, I'll give you a hint and
leave it to you to find
the answer to your question after your HSA numbers passed 1000 or so and you managed to make some
special and very simple tools for yourself. The task that looks impossible now, will be a simple routine after years of experience.
Your problem is you are relying too much on commercial tools. They won't help you on many cases. Just read again what experts told you before.
A hint, to work with WD drives you have to observe and control the head
movement. Make a simple tool as a HA fastener and a way to apply pressure on any
direction. So, you won't have to close the cover. The tool should be heavy enough to
to stop HA vibration when moving.
