I first noticed I lost one of my large directories then found out that it was reporting drive b was bad. After a power down it never came back up. The drives are a wd5000aaks-00tma0. I got EASEUS Data Recovery Wizard because of a link I found that said it worked. It worked fine for getting the files off of drive a, but drive b just locked my computer up. I swapped the PCB's from drive a to drive b and drive b has been working, but it will only recover raw files with no names. The files are basically chunks of the files I want to recover. Is this because the MyBook was set as RAID 0 and the data is stripped on drive b or is it because the PCB will only work with the original drive? If it is the second I need a price range for recovery.
Thanks for your time

PCB boards are not interchangable like that. You need to match the board with another one in order to change them out and then you have other things that need to be changed too like rom. It is not that simple to just take a board from one drive and put it on another. I think that you are right. If it is only a pcb board you should be able to find someone in your area to change this out for you at a reasonable price. Then if you realy need the drives recovered after that you can check with them on how much it would cost you to do this. Best advice take the pcb board off this drive before you damage the drive further. You can destroy more than you think if you mismatch pcb boards.

If your 1TB My Book had 2 5000AAKS drives inside as RAID 0, then you the EASEUS may give you the data back from Drive A, but you might get the files back from drive B with no filenames. (Just the generic numbers as the file names)

If you can recover files as raw files such as jpg, doc and etc, you might need to do the RAID recovery.

So far, you can't just swap the PCB between these 2 drives. If the problem was just the PCB, you can swap it but the data from the ROM had to be transffer to the new PCB before it can really function and read data off of the drive.

Wrong. There is JBOD mode in the MyBook. Use this method to recovery your Data: : http://www.rdm.kiev.ua/Data_Recovery/lessons/urok7.php

Good news, Turns out the only thing wrong after many many many hours of reading and trying to fix is, the little pads that make contact between the pcb and the hard drive were dirty. I know its hard to believe, but true. I have the burnt looking foam pad "worse then the pictures I found here" and tried swapping the pcb multiple times for many hours, but I took a pencil eraser to the pads on the pcb and put the book back together and it has been working fine. I completely recovered everything. Also as a side note, if this doesn't work for you, there is no software out there that can read these drives as far as I know, and I tried several.
Hope this helps someone out there.
