Hi everyone, I have a double failure on my archive drive and on the backup of my archival drive, so literally all my data is gone by now.I need help with the PCB repair, I contacted some guys who do sell PCB and do the ROM chip swap, but they are in China, and I do not want to risk shipping anything oversea at all.
I need help to find the PCB compatible with my drives, and/or someone who can swap the rom chip (or rewrite the data) on the new PCB, or even better someone who can repair my PCBs.
For now, I will take a guess and start to check the first 2 diodes D4 & D3 , it looks like some guys were able to fix the PCB replacing the diodes... I want to start with that even I can not visually find any burned/smoked part/area.
Below, the description of the HDD, and symptoms.
WD BOOK 750 GB
Date:06 jul 2008
PCB: 2061-701537-R00 AD XC 6Q05 0WWP M 0007010 9017 (sticker)
2060-701537-004 rev A (printed on the board)
HDD # 2
WD BOOK 1000GB SATA/8MB cache
Date:13 Ian 2009
PCB: 2061-701590-A00 AC XW7C18 EMTE * 0003280 9283 (sticker)
2060-701590-000 rev A (printed on the board)
There was no activity (zero) on the external enclosure, no led light, and no HDD spinning at all.
After i took out the HDD from enclosure and connected to a separate SATA adapter there also is no activity, no spinning, zero.It looks to me like is no power to HDD.
Than I connected the HDD (bare) to a SATA drive adapter. Nothing, no movement.I've noticed that the LED on the power source (of the SATA adapter) started to dim and blink anytime I plugged the SATA connector to the HDD, and went back to steady green when I removed the unplug the connector from the drive.
I unscrewed out the PCB bord and plugged the SATA adapter on the bare PCB, the same result....the LED started to dim and blink anytime I plugged the SATA connector to the PCB and went back to steady green when I remove the Connector, basically same warning light with the PCB connected to the HD, or with the PCB bare.
I made a test today, I mounted a PCB from an 500 GB old WD (similar, but not exactly the same SN), and I tested it for a second on the 750 HDD , and it started spinning (I did not wanted to let it run, because it can damage both PCB and drive), so I'm positive the problem is within the PCB not delivering power to HDD.
Thank you !
