My Book Essential 3tb External drive

I have several My Book Essential 3tb External drives - one suddenly died on me!

 

I verified via my other drives that the usb cord and ac adapter are working fine

 

The drive does not power up at all. No sound - No lights!

 

Drive not seen via disc management on any of my Windows 7 64 bit computers

 

I assume some power related part in the enclosure has failed.

 

Drive has not been dropped or banged. Working fine for months with about 2tb of data  on it

 

Working fine up until yesterday - Just will not power up anymore. Even tried pressing switch above usb 3.0 port!

Re: My Book Essential 3tb External drive

The fact that you have other drives will led to believe that you have a backup.. do you? 

 

Replace if the drive is under warranty

Re: My Book Essential 3tb External drive

enclosure or not you need to trouble shoot this.

 

If you not worried about warranty, then remove drive from the enclosure and connect it to a power supply.

 

If the drive spins then your enclosure is dead.enclosure itself performs the encryption by the way, so do not throw it out even if its dead.

 

If your drive does not spin up then PCB is most likely dead. Heads hardly ever get stuck on WD 3.5" drives.

 

do not initialize anything, or reformat anything

 

let me know what you find out about the drive's state, and I will let you know what to do next.

Re: My Book Essential 3tb External drive

Hi Guys,

 

I am living in Singapore.

 

I am having the same problem !!

 

But my drive still under warranty, logged this case and waiting for RMA number.

 

I bought my drive on  2012 Feb. and is not even one year, to my surprise.

 

Just wonder why do such case happen ?

 

Do not know if my data can be recover or not ?

 

Guess I have loss some confident on WD products....... :smileysad:

Re: My Book Essential 3tb External drive

HDDRS, I'm all ears!  

 

I ordered a PCB online just to see if it spins up.  YES.  disk management shows unallocated drive and I've heard something about encryption.  This board looks burnt by the way.

 

Will WD replace the board or should this "temp" board do the trick? I ran the WD lifeguard diags on it and it passed.

 

not sure what to do next.

 

(yes it's out of the enclosure of course at this point)  I heard the "USB Ding sound" and there it is but no files showing.  shows up in disk management but not windows.

 

Thanks.

Re: My Book Essential 3tb External drive

The data will probably be hardware encrypted. If so, then you will need the USB-SATA bridge board to decrypt it.

As for the HDD PCB, each board stores unique, drive specific "adaptive" information in flash memory. This chip, or its contents, needs to be transferred from patient to donor. It is usually located at U12.

The following PCB suppliers offer a firmware transfer service, either for free, or for US$10:

http://www.donordrives.com
http://www.onepcbsolution.com
http://www.hdd-parts.com

I would advise that you avoid those suppliers who don't tell you that a board won't work without modification. Often they will attempt to obscure the requirement for a firmware transfer by deceptively describing their products as being "for data recovery only".

Alternatively, if you are not adept at soldering, your local TV/AV repair shop should be able to transfer the chip for you.

Some PCBs do not have a discrete serial flash memory chip. Instead they store the adaptive data inside the Marvell MCU (the largest chip). In this case you will need a "PCB adaptation" service.

The following PCB supplier includes such a service for free:
http://www.donordrives.com/services

Sometimes the problem is as simple as a shorted TVS diode, in which case the solution is to just remove it.

See http://www.users.on.net/~fzabkar/HDD/TVS_diode_FAQ.html

... and http://www.users.on.net/~fzabkar/HDD/ (photo clips)

Could we see a photo of the burnt area?

Re: My Book Essential 3tb External drive

I hope this helps...not the best quality but thanks for your time...I'm at work now, but I'm going to get crackin on this ASAP...you've given me the most helpful info I've received in like... forever!

Re: My Book Essential 3tb External drive

[ Edited ]
@just1rob, in your case the HDD appears to be OK. It does seem to be an encryption issue now. As for the "burnt" appearance of the replacement bridge board, if you are referring to the area around the mounting hole, then that's probably just oxidisation, in which case I wouldn't be worried about it.

The first thing I would do is to verify whether your data are indeed encrypted. To this end, I would use a disc editor to view the contents of sectors 0 and 1, in hexadecimal mode. (In DMDE, choose Mode -> Hexadecimal)

Roadkil's Sector Editor:
http://www.roadkil.net/program.php?ProgramID=24

HxD - Freeware Hex Editor and Disk Editor:
http://mh-nexus.de/en/hxd

DMDE (DM Disk Editor and Data Recovery):
http://softdm.com/download.html

If the data are indeed encrypted, then I can see two possible approaches for you. Either repair the original board, or transfer its firmware to the replacement board.

Your photo is difficult to work with, but near the largest IC (Initio INIC-1607E ?) there should be an 8-pin IC, probably with a "25" in the part marking. This chip contains the bridge firmware. If you are not adept at soldering, your local TV/AV repair shop should be able to transfer this IC for you. Whatever you do, don't damage it.

The alternative approach of repairing the bridge board may not be as daunting as its sounds. I suspect that there may be a device in series with the power input that may be damaged, or it could be that an 8-pin dual MOSFET chip has burnt up. The MOSFET is an electronic switch that supplies +5V and +12V power to the HDD. If this IC is damaged, them we simply remove it and jump its two switches with jumper wires. I can show you exactly what to do, if you provide me with a detailed, close-up view of the board.

Re: My Book Essential 3tb External drive

 

 

 

First thing I did was get you a better picture.  hows this?

the patient board had no power at all...no light, no spin.

Donor board lit up right away and drive spun up upon hitting the power.

I'll take a look at the contents next.   Thanks again

Looks like encrypted (if I did view correctly).
