Strange situation on a seagate ST3750330NS

[Alkemist]

Just received a defective seagate ST3750330NS.

Connected on my PC3K drive will not spin and still on BSY (but not full green just only light green).
Supposing problem on faulty PCB I swap rom on a donor PCB but result is same
Most strange is reverse: moving donor ROM on patient PCB will have same result.

Rom damaged? .....I can read it with external programmer... so just corrupted?

PCB is: 100866424 REV B

Some suggestions?

That ROM is from a TLITE1HD 7200.9 model, not a ST3750330NS.

What is a "100866424 REV B" PCB?

In dont know ....

Client said other company have try to recover this disk before of me (I guess he have try some DIY solutions like swap other disk PCB).
But 7200.9 disk have different shape of PCB so probably client/other company have rewrite ROM of this PCB .............It is just a guess

Can you provide pictures of both the PCB and the drive?
I've never seen this before.
