My logic board went on my hard drive before my monthly backup. (Always
works out that way.) Anyway wanted to pull some data off the drive
before I scrap it and need a transplant. If you all are like me you
have old drives lying around all over the place. It turns out locating
this board is a little harder then I thought (went through my "to
junk" pile at work 30+ HDs and only found ,1 but it was the wrong bios
version.) I was hoping someone might be able to hook me up. This data
isn't critical or anything so I'm not looking to drop a lot of $$ but
will be willing to trade or pay shipping etc. if you have it. Here is
the info:
WD400 (RECERT)
MDL:WD400-00DNA0
DCM:HSCHCVJAA
LOGIC BOARD IS : A "100 EB" (this # is the 3rd set from the left off
the barcode on the board ((just to the left of the slave jumper))
BIOS Ver. is: V7163 (this is found on the back side of the board)
1 last think to note is that WD had 3 types of boards for these 40gig
drives. 1st one looks like an "L" and the other 2 take up the top 1/2
of the back of the drive (mine is this type) out of these 2 mine is
the 1 with a notch in the board (top left side just under the screw
and this notch corresponds with the side rail screw hole)
It would be great if someone could help me out.

You will need to find a matching PCB which could well come from another
drive.
On the PCB, generally at the edge, is a number etched onto the board
beginning 2060-xxxxxx.
You need one of these.
You need to desolder the ROM chip from your failed board and place it on
the replacement board.
Simply swapping PCBs is not going to help at all.

While possible with (good) amateur equipment, this is a major
challenge. I would not recommend trying it, unless you have
a decade or so experience with a soldering iron. Even then,
using the time needed to earn some money instead and giving
the job to a professional may be more cost effective.
Need WD logic board!!!
