Western Digital head alignment issue and tools

[Alexii]

I have a much simpler solution and costs about 100x less

WTB =)

Any suggestions or cheaper ways to handle head alignment in these drive ???

It's not just tools; solving this problem requires understanding of and familiarity with these drives as well as a set of best practices. We developed our own alignment jug which we not only never resold, but never use because it's not needed.

I'm currently recovering a Buccaneer that was dropped, using a DDI for imaging, and changing alignment on the fly.

Hi guys can someone of you share with me your solution or best practicies? I know that the topic is very old but may be .....
My friend ask me to recover his data from old WD800BB. Someone before me open the cover and now disk is clicking several times and then stop. I bought used one HDD with the same MDL and DCM 100% working. As i assume first i shoud try replace heads.
i've read that after opening they need to be adjusted, so i have an idea to work with HDD without cover and using small gasket with screw not tighten, find the most central position for head arm.
To be honest im not sure if the damage is related to the heads (beacause the cover was opened) and first and before i open next HDD i will try to chceck if this one.
Im not a professional in HDD area but as a fine mechanic specialist i undesrtand how they work Just need some advise from pro. All accept "you can't do it"

What's the pcb number (2060-70xxxx ?)

PCB number is 2060-001159-006

Then it is probably not the common issue the 701335 and 701292 pcbs had with bad feedback on -5V supply, which caused this to rise to insane levels (sometimes i measured -25V). This overvoltage caused uncontrolled writes and damaged the preamp on those drives. Recovering the data was not trivial from those cases. I don't have much time to check one of the 1159 pcbs right now, you may check it if you want (i am not even sure without checking those have -5 or +8V aux supply to the preamp).
In any case, even though you wanted 'all except "you can't do it"', i must say you have pretty low chances with this thing.
