WD PCB ROM SWAP QUESTION

[daRecoM]

Hello,

I've this WD USB 2060-771961-000 PCB that I wanna access from PC3k. So I have SATA 1960 and I swapped patient ROM over it like I always did.

I first turned it on from Data Compass and it powered up (status show 'busy', expected), plugged it to PC3k and power on. --> not spinning up at all. I first thought it could be the soldering that causing the problem but no it wasn't that.

What i've tried so far

1. Power up the HDD with patient ROM chip --> not spinning

2. Power up the HDD without patient ROM chip --> not spinning

3. Power up the HDD with another PCB --> Spin up

4. I used 2nd unit of 1960 PCB with patient ROM chip --> not spinning

Strangely, it will always spin up the HDD right after I've swapped the ROM chip (from Data Compass) and it will not spin up when I connect it to PC3K

It seems to me like the ROM chip has 'killed' the PCBs? How can it be? I mean the 2 SATA PCBs are completely dead now .. it will not power on any HDD.

Please help

Thanks in advance.

did you solder the rom chip ?

I wonder why someone would do soldering of WD PCB ROM when they have pc3k...

if you use pc3000 and ROM is missing(not soldered on PCB(and not integrated in MCU)) or ROM is not good soldered to PCB, indicator which shows that is, that all status indicators lit
