The above drive is not being recognized. I have a matching USB board (rather than a SATA donor). Original board is 2060-771801-002-REV A. The donor is identical but from a 2TB WD drive. Swapped the U12 chip. Drive name up in R-Studio, but as write protected. The drive is seen in Device Manager but as unallocated space. I presume this is an encryption issue? I also swapped U14 as a test but the drive clicked. Any help would be appreciated.

Maybe your 2TB has a different decryption chip? Post a pic of each board.

I am a little confused about encryption with these USB boards (will come as no surprise to you ). I know that MyBooks have the USB bridge encrypted (symwave etc), so I presume these drives have encryption embedded into the logic board. But if that's the case how can you use a donor SATA board to read the drive? (as read in this forum) Or are 2.5" and 3.5" drives encrypted differently? Will post pics first thing tomorrow. Thanks.

It doesn't have a password set?

Not sure. As the drive is showing as unallocated space, I cannot get into it to look if its Smartware etc.

Are you saying the encryption is handled by the U14 chip? I did swap this over and the drive clicked. I guess it could be corruption of the U14 chip? I will try swapping again.

Further to this. I must have done a bad soldering job on the first swap of the U14. I can now get into Hex and can see the drive however it is still encrypted. If the encryption is stored in the U14 chip, then a new donor will not make a difference. Or is it stored on the Controller chip and an exact matching board in terms of model number etc should work (with U12 & U14 chip swaps)?

The chip to the left of U14 is a JM does that match the other pcb?

The first numbers are the same, the rest are not:-
Patient: JMS538S 1216 QGCA2 B E73T10019
Donor: JMS538S 1232 QGCA2 B F74DR0019

I have also been told buying WD Smartware Pro software might help?

"1216" and "1232" appear to be YYWW (Year / Week) date codes. The last two markings could be batch codes. In short, I don't see any significant difference.

My guess is that you have either a bad head, or bad sectors in the area where the encryption key is stored (hidden lba area at the end of the drive). Even if the drive didn't have a password set, it still encrypts the data and needs that key to decrypt. Otherwise it shows write protected.

I'd suggest that you set up a SATA board so you can tell what's really going on.

I've dealt with these drives more than I'd like to, so feel free to PM me if you need help.

I did look for the encryption sector but couldn't see it, so you could be right.
I will try a SATA board and take it from there. Much appreciate the advice.

By the way, if you have done a few of these, do you know a matching SATA board for 2060-771801-002-REV A.
Thanks.

How about this one?

The board appears to use the same MCU and motor controller.

What about this http://www.hddzone.com/wd-2060771823000-pcb-p-337.html

2060-771823-000

Main Controller IC: 88i9346-TFJ2

Screenshot of LBA0 would be useful to understand if drive encrypted or not.
The 2.5" PCB does encryption itself. On 3.5" drives it is adapter of box that does encrypt data. (MyBook USB-SATA bridge board).
So, 2.5" Sata PCB would be better solution + JMicron adapter from MyBook.
There are some cases with corrupted key sector in LBA zone, you can get and copy it from SA.
For JMicron it is mod25 by offset 0x200 (size 0x200).

@sasha. There is a download of LBA 0 in text under the PCB picture above.

Any way to upload first 512 bytes in bin or screenshot of hex? Just nearly broken my eyes looking at text-hex

LOL. Sorry. Will do it when next in the office.
