I think it should be fine, but I normally try to get a better match (5th digit also). Donor on right.

What do you think?

THANKS!

Hello mediaman,

I think that the left one PCB : xxx 1590 xxx
and the right one PCB : 1552 or 1537 I can't remember excatly

head swap will not work on two different drives.

I do not think the DCM code has any relevance on the ROYL drives. I think more important is head map match and family match.

@ hddguy,

Agree.

I appreciate the feedback.
Unknown: I will look at the PCB's later when I get to the lab.

Any tips for correct donor matching on these drives? I was sure, and have had success before with 5 and 6 DCM digits (on smaller WD's), but i have also always looked for a better match in other areas (date, -00xxxx etc)

Thanks again for your patience and help.

Uknown,

Here are the two PCB's, you are very right about differences.

Any tips on HSA matching criteria for donor?

Thanks

Head map match and family match that's all, like Mr.Hddguy said.
