WD3200AACS Spider Head Replacement Problem

[murphman]

Hello,

I had customer with WD3200AACS-32ZUB0 (DCM: EHNCHT2CA) with a degraded head (1). I did head map in DE and imaged the drive on the functional heads.

I could not find an extract donor so I ordered WD5000AACS-00ZUB0 (DMC: DANCHT2CAN). The replacement went well, the hard drive is recognizes and reads all modules without an issue but it will NOT read logically. I put the customer (degraded heads) into the donor and it also recognizes, reads all modules and can read logically (minus the failed head).

So... I dont understand, why does the donor head not work in my customer drive (or at least doesnt read logically) when the failed heads have no problems reading on the donor drive.

Any suggestions? Thank you

Try writing mod 47 from donor ROM

I tried writing rom module 47 from the donor but that didnt help.. also I just noticed that it only reads service area only from one head.. im kind of at a loss

Hi,
Keep the original mod 47 into patient then read micro jogs from patient and average them out from donor rom ,Then try ,Acelab has a blog for this on blog site
