I have spent all day reading this forum and others, and have learned a lot having started near zero. Particularly thanks to fzabkar. I just need a few things clarified.
My HDD crashed while running XP, briefly gave some error message I did not see myself, and shut down. No prior sounds or signs that it was failing. Now BIOS will not recognize the HDD, and it doesn’t spin up at all. I noticed it got very hot/smelled slightly burnt in one single spot on the logic board. Took off logic board to inspect drive side, and there is apparently a burnt out chip in that same area. I believe this chip is “L6283, SMOOTH, spindle motor + VCM controller, ST Microelectronics” according to fzabkar’s HDD IC file.
Is the burnt out chip the “motor control chip” (so motor control chip is aka VCM controller )?
Do the photographs indicate I need a new PCB and should ignore trying to find and test the TVS diode (I was hoping for that easier solution)? If No, where exactly is the TVS diode on my board? I can’t find an image of a similar looking board as mine.
What are the minimum specs that need to match up when getting a replacement PCB? I haven’t been able to clarify if I just need to match the PCB #? Or both the PCB # and the MDL #? Or just the MDL #? (I am aware that I will need to transfer the U12 firmware chip and I already know how to solder.)
Thanks in advance, and especially to fzabkar, I learned just about everything I needed from your posts!
