Hi, I have a drive which I cannot get going (its been in the shop for 2 weeks and the customer is getting tichy).
It is a 200GB SATA, original symptom, no spin up and one of the ferrite cores on the PCB was burnt out.
Model:ST3200822AS
P/N: 9W2854-301
HDA P/N: 100314751
Config: A5D-07
Firmware:3.01
Date Code:05072
PCB Code:100306335 F 7504B42M
Product of Singapore

I have swapped the burnt our component, no difference so probably something further downstream.

I have 2 spare similar drives:
Drive 1:
Model:ST3200822AS
P/N: 9W2854-301
HDA P/N: 100314751
Config: A5D-08
Firmware:3.01
Date Code:05185
PCB Code:100306335 F 7517DDM2
Product of Singapore

AND
Drive2
Model:ST3200822AS
P/N: 9W2854-301
HDA P/N: 100314751
Config: A5D-08
Firmware:3.01
Date Code:05272
PCB Code:100306335 F 352552TM
Product of China

When I swap the PCB the motor spins up and the head seeks, but then rests (drive spinning floating, just like the .11 ones do with SD15/BSY) in the middle of the platter so it appears to now be a not exact enough board match.

My questions?
In the Seagate config code what is the difference between A5D.07 and A5D.08?
Can I overcome this difference or do I need a more exact match (firmware swap, something else)?
Can anybody guide me towards fixing the board when I get some time, I am reasonable in terms of electronics?
If I need a more exact match anybody have one the want to sell/lend/rent/swap?

Thanks in Advance

Cancel that. I have got it working (12V TVS was short circuit should have checked it first!)

All good. Tx.

hi,
please send high qulaity images of your PCB both side to me by email. have you swap the original ROM to good PCB when you swap PCB?
