WD Spyglass heard swap practice

[epeace2009]

Hi

I need help how to choose proper donor for these Spyglass, Spyglass2 and 3 type of drives?

What to watch on sticker regarding good donor except model and date of production?

Is there some info on HSA also which can give us info are heads compatible?

Is there difference when looking for these info for SPG1 , 2 and 3, Ultra ?

Thanks

Any Spyglass (1,2,3, UL) heads work in any Spyglass drive. First SG1 models have used (very rarely) different type of heads but it seems that WD stopped doing that, at least in North America. 

4TB SG3 models sometimes use 8 heads and not 10, so be aware of that.

Thank you for answer. Today I swapped for the first time successfuly  heads for WD5TB SP2 Ultra! :D

Now I have problem with slow reading. Is there any solution for these type  of hdd for slow reading????

Block SA writing, I find this speeds things up a bit!

Slow responding in RAM (RAM only) can also help.
