Messed up PCB's WD

November 2nd, 2017, 18:12

Hi guys! The customer brought 15 water-bricked Western Digital HDD (wd20earx-00pasb0, wd20ears-00mvwb0 etc.). Most of the PCB's was fixed, but as it turned out, the client had removed all the PCB for drying and thinking that they were all the same, put them back on the HDD's in a random order. How do I determine which is whose and whose is which?

If you have ROM reader of some kind, you should be able to get the SN's from the dump.

What are the date codes on the labels? Compare these against the YYWW (Year/Week) date codes on the chips and the WWYY date code on the PCB.

If you need it, I have written a tool that can analyse your ROM dumps.

Code:
Analysing active 0x0D module ...

Firmware Version = 01.01A01
World Wide Name = 50014EE25F3D3A7C
Model Number = WDC WD20NMVW-11AV3S2                   
Serial Number =

Thanx bro. Getting rom dump is not a problem at all. The problem is that I dunno what codes/lines I have to compare. I tried to google online, but could not find definite answers. Another question is, how do I open the dump file? Would it be enough to just use HEX-editor? If so, what line should I look for? Thanx again and forgive me for taking your time.

Thank you so much for replying bro! It would be really nice if you could share the tool you speak of!

Thanks so much! Could you please tell me how to run the wdromv11.exe file? I tried to run it under Win 8.1 but nothing happened.
