Hello,

I have a WD5000BMVW 500GB USB disk. No clicking sound and do not recognized on PC.
I swap ROM chip from USB PCB 771814 to SATA PCB 771820. Then connect it to PC3000 and no green lights on PC3000, seems disk is dead but I swap the ROM chip to 3 different SATA 771820 and same result.

Any idea why do not work?

Rgds,

try to read the ROM with an external programmer (or any other way), and take a good working PCB and flash the ROM with a programmer or using PC3K.

+ 1 Agree.

Its either the ROM checksum doesn't pass or pre-amp.

Hello!

I found myself in a similar situation and it was the ROM, damaged. So i had to rebuild ROM from SA using PC3K and flash it to a donor PCB.

<Good luck

Yeah it is ROM damaged.

AdrianSRD, was your disk a USB drive like mine? Which type of donor you choose, a match USB drive?
I was speaking with ACE Support and their solution is just for drives with internal ROM (no U12 chip). My disk has an external ROM.

Any other ideas?

Hello,

Amarbir, If it is a HSA Short, would the disk try to read with a good PCB from another disk (without ROM changed)? Can you please share with us how to test HSA Short?

Jermy, I can read the ROM in the TL866. File attached.

Thanks.

The ROM looks OK.

If you want to test for a shorted preamp, upload detailed photos of both sides of your PCB.

Thanks fzabkar,

Here are the PCB photos. The ROM is not on the photo as I took it out to read in TL866.

Can you measure the voltages between ground (any screw hole) and each of the 18 pins at the HDA connector on the PCB?

Hello,

Just measure the voltage as suggested and I got value between 0.13V to 0V.
What should be the expected values?
What are we testing here?
