Hey guys!

I have a disk with burn motor controller IC (hole in the chip). I can find absolutely nothing about that chip so my best bet is to get the new board for the drive. Should I swap only the motor controller IC or complete board?
If I go with the second option and since there's obvisouly no memory/bios chip on the board, my question is this: which chip I need to swap to get the board from another disk? I'm guessing the main controller chip (the low-pitch) ?

I'm attaching picture of the board.

Thanks for all your help.

can you post model and date

Can you identify the firmware version? Has the drive ever received a firmware update?

Hey guys. Where can i find firmware version? On the backside there is m17-160-mj and s.0711b 36-14. I dont know which is firmware version. Disk model is hd501lj. Do you think that just replacing the motordriver will not work? I ordered used disk with the same model number, hopefully i can work something out with it. Thanks for all the replies.

Oh, forgot the date. It's 2007.12.

Here is an example:

F/W : CR100-10

In your case ...

PCB --- BF41-00133A Trident 11-RE Rev. 06

ICs and YWW/YYWW date codes ...

88i6725S-TFJ1 0747
SDRAM 743
transistor Y749

ISTM that the manufacture date would be early December 2007.

If you choose to swap the motor controller, I would first test the components around it for shorts. Also test the motor windings.

Hey. I got a donor drive, removed the pcb and installed it on my disk and everything worked perfectly. I'm surprised that I could actually replace this so easy, was expecting more troubles

Thanks for all the help.
