Quantum Fireball Plus AS60 woes

[Peterc]

Good morning, afternoon, evening gurus,

Let me begin with a sigh
(sigh)
Okay, the above drive was initially not spinning up. Swapped PCB and now it spins and IDs but not copying in DE. Does this drive have a NVRAM or ROM that needs to be moved over or is it a SA problem? In PC3k, there is no choice for Quantums. Universal Utilties will not allow me to copy data from donor so that I can copy to patient. I thought Maxtor might be a choice, but no.
Any opinions or direction for research would be GREATLY appreciated.

Thank you.

PS. The PCB has a cover on part of it. When I removed the cover, I noticed a small component that appears to have damage. On the donor PCB, the same location of the previous component, there is a component that seems larger then the patient one. The component on the donor PCB reads:"352A" Significance?

Thanks again

Hello,

If i understand right, first you have one damaged pcb, and maybe one damaged preamp as well.
Next thing what you have done, replaced the pcb with similar, wich have another read channel chip, and on the next power up the read channel is damaged.

Great.

This drive have the initial ROM in the MCU, and this may be differs too, so it is a little complicated to find another matchig pcb.
If you haven't got a lot of donor drives, the best step is to repair the own pcb and measure the preamp before you start again the drive.
Additionally, you should use a protector fuse to prevent another damage of the pcb....

Regards,
Janos

Please post a hires photo of original PCB and possible donor drive.
For these drive I have a proprietary solution but I'm at the opposite side of the world... damn !
What is the code on the bottom of the damaged drive (white paint like AASY 1540, AVQ3 0300 etc. etc.) ?

PCB picture is damaged PCB. Drive picture is donor. AASY 1310 printed on patient.
