# What do I need to know to replace the PCB of the WD Caviar Green Hard Drive

data-recoveryhard drive

I have a dead 1.5 TB WD Caviar Green hard drive that I'd like to try to fix by replacing the drive's PCB.

The drive was housed in an external enclosure. After a power cycle, neither the drive nor the enclosure would power up, and the computer would not recognize the drive as being connected. I tried it in a different enclosure, with the same results. I suspect that the 1st enclosure has damaged the drive's electronics (this is the second drive it's killed in this way) but the data on the platters is OK.

Here's the drive's information:

From the top sticker:

Model : WD15EADS-00P8B0
WWN: 50014EE0AC71C1AC
DATE: 11 NOV 2009
DCM: HARCHT2MA
LBA: 2930277168
5VDC: 0.70A
12VDC: 0.55A
R/N: 701640


From the PCB:

Printed on the board itself: 2060-701640-002 REV A
On a sticker with a bar code: 2061-701640-202 04PD1 XW 8R41 UTMD 6 000 4180 0184


Here's some images of the drive:

My questions are:

1. I understand it's very important to get an exact match to successfully replace a drive's PCB. Which of the above information is relevant to a match, and which of it is irrelevant?

2. What are some good places to get replacement PCBs for hard disks, or places to get a matched drive to harvest a PCB from?

3. If you've replaced a PCB of a hard drive, what what you experience?
