PCB or SATA/USB interface or whatever you like to call it inside My Book Essentials, died. I’ve had a backup of the disk about 1 day old, but unfortunately, the interface died just before I could make the backup - in the middle of theusage. The external drive was WD MyBook Essential WDBACW0010HBK-01 4912B (S/N: WMC0T0895079 R/N: C3C) . Of course I disassembled the enclosure and connected the disk to a 3rd party sata/usb interface. Unallocated partition was found. Interface had the following tags:
4061-705094-001 Rev AD
chip JMS538S (1213 QGCA2 B E73SS001S)
After days of googling these were the options:
- Professional help
Reallymine (creates a decrypted image of the disk)
Linux-mybook-tools (eumlates the encoding/decoding chip)
- Buy a new sata/usb interface with the same chip (after you’ll reconnect you’ll have to recover the partitions).
I’ve decided not to ask for professional help since the drive was encrypted and they would probably go after the other three options.
I’ve somehow managed to make reallymine work but it took 2 days to recover 100 GB out of 1 TB. I did have success with linux-mybook-tools. I can say that linux-mybook-tools require a level of skills but getting files out of the drive is faster than with reallymine. So I cannot confirm the success with reallymine, but I can confirm linux-mybook-tools work.
In parallel I was lucky enough to find a used MyBook Essentials (P/N: WDBACW0010HBK-01 5212B, S/N: WMC0T0825167, R/N: C3C CBCLEA). Of course I bought it. Fortunately the interface inside had the same chip and the similar enough model:
4061-705094-001 Rev AD
chip JMS538S (1216 QGCA2 B E73SW0019)
To make long story short:
Find a drive or, even better, try to buy a new interface*
Connect the drive with the new interface (you’ll still see unallocated space on the drive)
Run a partition recovery tool (in my case EaseUS Partition Recovery)
Then it’s just a matter of few clicks and one or two minutes
First of all, it has to be a match with the chip and second, it has to be also a match on the first four numbers and the revision ID also. If there’s no match, try directly with reallymine or linux-mybook-tools.
It worked for me and I keep the fingers crossed for anyone to work also for them. In any case, don’t format the drive, don’t create new partitions, do not write on the disk.
Last, but not least, WD, “thank you”. I’ve contacted all the listed companies in one of the EU countries. One with no reply, two replied that they do not sell the interface but offered to help for a larger amount of money. If someone buys a product which supports encryption and he/she does not set up a password, do not encrypt the drive. Especially if the interface is a link so weak, that many of us almost remained without some or all of the data. WD, at least, you could offer some replacements for the interfaces. I would definitely buy it and it would save me a lot of time. This is a big fail for you.
Edit: I can send the working interface to someone if she/he needs it (EU only). Send me a private message.
