WD HDD Head Swap Experiences

[Jared]

I think it might be nice to have a thread here for unusual head swap experiences that worked.

Here's mine from today:

Patient:
WD2500AAJS-75M0A0
DCM: HANNNT2CH
Date: 30 Aug 2009
Head map: 0, 1

Donor:
WD3200AAKS-00L9A0
DCM: HBRNHT2CGN
Date: 01 Nov 2009
Head map: 0, 1

Works perfectly and imaging at 35MB/s

I wonder why/how you get to the step of testing such a different models.
What makes you go that way?

same family, same HM is not so diff.

Was an expedited project and the donor was one I had in house already. Normally I might not have tried it, but because of the urgency, it was worth the risk of ruining a drive. Besides, in my estimation the correct factors did add up: Family, Headmap, Date, critical two digits of DCM. So I went for it.

I think it's worth keeping track of these experiences because it confirms which models are definitely cross compatible for heads.

Source of the post critical two digits of DCM

is it the 2 digits after the T?

In this case it was the T2 I was concerned about:

"HANNNT2CH"
"HBRNHT2CGN"

That's the really critical part. Normally though I'd try to match the NNT2 part, but it's not as critical.
