I am currently using hard drive number. Previously I was using pcb number as 701267. But now I can’t find it. Does anybody know alternative pcb number for WD hard drive. Please post valid numbers.

One can’t find pcb number for wd hard disk. This is a common problem. I have some alternative pcb numbers which will help.
1-701590 you can use 701537
2-771590 you can use 701590
3-701267 you can use 701266 (ROM swaps needed)
4-701567 you can use 701537
5-701596 you can use 701590 or can use 701537
6-701477 you can use 701444
All these numbers are tested.
PCB number 501567 and 501537 are not compatible.
Are the wired signals in connector J1
701537 -> J1 pin 1 is connected to GND
701567 -> J1 pin 2 is connected to GND
thus, these 2 PCB are interchangeable only in few cases. Not every Rom is compatible with PCBs with these 2 numbers.
Use multimeter to find where on connector J1 is GND at 701567 and at 701537.
You can find some versions f Rom that will work with 88i8846-TFJ2 MCU and on 88i8845D-BHG2 MCU both. One such ROM is Atlantis ROM 05APE_04AD.
Some versions of ROM when saved to PCB which is equipped with another model of MCU which kills PCB. These PCBs works with j-tag and tiny consoles.
Rom such as Pinnacle ROM 052JA_0427 written to the PCB with MCU 88i8846-TFJ2 kills PCBs.
Even not every model of PCB number 701590 are compatible.
2060-701590-000 REV A - MCU 88i8846-TFJ2 (internal ROM) and
2060-701590-001 REV A - MCU 88i8846E-TFJ2 (external ROM) are not compatible with each other.
