Hi,

WD my book essentials 3TB (was used as one partition 2.7 TB), the card in its rack started to fail (the card had some black smoke on it like something was burned, it was working on & off so I could not copy my data from it which was about 2.2 TB the data was sometimes there and sometimes most of the directories are empty), so:

1- I attached it to the PC internally, the disk was not recognized by Win7 in my computer, but was visible from the win disk management in the control panel.

2- I have used it to unpartition then repartition to MBR (but found that it had split to 2 disks - Max partition size was 2TB in MBR so then I repartition it to GPT (probably done this step twice) then formatted it.

3- Normally I thought that I can retrieve the data from Linux boot disk with ddrescue or recuva but it failed, because I have never done it with a HD that was that large and didn't know that the disk was formatted in a different way.

4- I did not write anything on the file ever since.

5- I have tried to recover the partition & the files via Hanyrecovery, R-Studio, EASEUS Data Recovery, Stellar Phoenix, EasyRecovery, photorec and Test Disk, but all failed to see the old partition & they see only the data from the new one, and get gibberish results (like an image with 1.5 GB, which I know that was originally an ISO file).

Note: the program TestDisk had so many promising options but I didn't want to mess with something I did not know so that I would not reduce my probability in getting my data more than it is.

I've been trying for the part 3 weeks, can someone please help (The HD contained very essential data for my & I know it is till there but the problem is getting it out).

Thanks

You removed the partitions, created a new patition and then formatted it. Your data is gone. Contact Data Doctors. They might be able to help.

Somehow, when you formatted the drive, you missed the part that says, "WARNING: Formatting will erase ALL data on this disk. To format the disk, click OK. To quit, click CANCEL."

Formatting removes all of the labels of where everything is on the drive. If you had stopped there you may have been able to recover some of your data. However you then created a new partition which wrote to the drive a new space for labels that was completely blank. so you not only removed the labels but then you created a drive with new labels that all say, 'there is nothing here'. That is why you cannot recover any of the data on your drive manually.

Yes, the 0s and 1s of your data are probably still mostly intact however you will need to use professional recovery services to get any of the data back, which are very costly. The only other problem you may have is that using all of the data recovery software that you did may have hurt your chances for recovering the data even more.

Thanks for both of your opinions & support, I'm aware of what i have done (i have already recovered data from formatted partitions like this before but not after repartitioning it). and i didn't have anything else in mind to make the drive visible again.

& I'm aware that the last resort is using a professional data recovery company that uses a clean room to recover the data.

However if there is still possibilities to try especially with TestDisk options, i would like to try them any other idea's?

for example: when i tried to recover the boot sector & file system i got the following msg before choosing the advanced option.
"Warning: number of heads/cylinder mismatch 240 <NTFS> != 255 <HD>
Status: OK"

You could try Vimx Partition Recovery, which specializing in recovering data after accidentally deleting or removing a partition.
Actually, a false or bad recovery tool sometimes cannot recover your data. Oppositely, it may damage your original data again. Therefore, even though this partition recovery tool may need some money, it is worth that.
Note for you:
1. Do not store any new data on the same drive to avoid original data overwritten by new data, which can make your data gone forever.
2. Do not save the recovered data on the same drive, which can cause recovery failure.
3. Do not forget to create a new partition, if you need. (Here are the ways for you: Right click“My Computer” to select “Manage”=> Choose “Disk Management” => Right click the deleted or removed partition and hit “New Logical Drive” on the list => format it.)
4. Do not forget to back up your important data regularly in the future.

No data recovery software will be able to recover even a single byte of your data ... until you reinstall the drive in its external enclosure. This is because your data are encrypted by the USB-SATA bridge firmware, even if you have not set a password, or explicitly chosen to encrypt your data.

Moreover, WD's 3TB My Books are configured with 4KB LBAs. When you remove the drive from its enclosure and install it inside a PC, you expose the drive's 512e LBAs. This means that sector 0 is still in the same place but every other sector is out by a factor of 8.

The original partitioning scheme was MBR, not GPT. A 4KB sector size allows for a maximum MBR partition size of 16TiB whereas the traditional 512-byte sector size limits the partition to 2TiB.

Ok what you say seems a reason why I have been not able to get any file with all the software i used.
now, i can get a new board & put it back with the HD in the rack of WD but should i do anything with it or just try to recover as is?
i believe if i connected it windows might not see the drive OR it will see it as raw and needs to be formatted, what shall i do then proceed with format or try to recover as is?

thx

The new board needs to be matched, otherwise it won't be able to decrypt your data.

The problem now is that you have trashed the start of the user area. These data will show up as garbage, whether or not the PCB is a match, so you could still be scanning your drive from start to finish without finding anything.

To avoid wasting your time and thrashing your drive, I would start by using a disc editor (eg DMDE) to scan for boot sectors. There should be a backup NTFS boot sector at the end of the user area. If you can see this, then the replacement board will be a match, and you can then try to recover your data.

I had a similar problem with a 2tb Mybook. What I discovered is that the mybook disk format and partition information is contained on the board with the SATA bridge inside the enclosure. This is why partition recovery does NOT WORK in this case. I tested this by buying a similar MyBook version and looking at the disk structure while in the enclosure and after it was removed from the enclosure. The result is without accessing the drive through the enclosure, the drive will appear as all unallocated space and disk management will view it as not initialized and not formatted. SOLUTION - (1) Buy a similar version of your Mybook ( I suggest if you need an older MyBook - go to a small mom & pop computer store). (2) Take the new Mybook apart (careful it's only 4 little plastic clasps inside the enclosure. (3) Swap your old MyBook drive for the new MyBook Drive. (4) Plug & Play, you'll find all your files intact and accessible.

RECOMMENDATION - Copy everything over to a ANYTHING BUT a MyBook. Throw away MyBook and get a hard drive enclosure that does not hold disk format, partition, or anything else on an intermediary board. This was a bit of a ripoff because it seems like lots of people have had this problem. Western Digital will not sell you the board, but they will sell you their data recovery services (which probably involves the same steps I just shared for an additional minimum of $500.00

Did you find the backup boot sector or was it just the board that worked. I have a 2tb mybook that is having the same problem and am going to try and find a replacement board on ebay. if you used the backup boot sector how did you put that in place?

(I have the WD 3tb usb 3.0 back in it's enclosure and the computer is still not reading it). Can you direct me in the right direction so I can access my data. {This is what I have done so far by reading a few post. I removed the drive out of the enclosure, tried looking for it my computer, found it in disk management, it wasn't initialized and still unallocated but I think it some how created a partition, then I noticed it was online so then I tried to initialize it, could not detect it. So I put it back in the enclosure with the sata bridge attached in all, and now I am at the and my computer will not read it through the usb either}. Thanks Ian

Hi fzabkar,

I'm in a situation just like this.
I have a working 3TB WD Red drive that i'm using with my Probox (HDD Box). After my Probox died i had a hard time looking for a replacement, and since i had an old WD Mybook i had the "brilliant" idea of putting the 3TB drive in it. At first the Mybook read the drive correctly, i can still read and write to it, for a few days. However one day the drive no longer showed up, and it said i must format it to use. I took the drive out of the Mybook and put it back in, I tried your suggestion but DMDE showed that the partition is too large and cannot fit (the Mybook is old and can only support up to 2TB i know now). DMDE also cannot find any partition... So did i mess it up ? Anything you can suggest i try now ?

Sigh thats like >1 TB i have no back up of...

Many thanks if you can help me with anything ...

@Duy Hung, it appears that your My Book has a 32-bit LBA limit. When you wrote data beyond the 2TiB point, it wrapped around to sector 0 and trashed the start of the file system.

Your data should still be there. If the MFT is intact, then you may be able to recover the original file and folder names, otherwise you will be left with a raw recovery.

If it were my drive, I would install it inside your computer and quickly examine some critical sectors before throwing any data recovery software at the problem.

Specifically, I would examine the last two sectors of the drive, use them to determine the location of any boot sector and backup boot sector, and then use the boot sector to locate the MFT. If the MFT is undamaged, then your prospects would be good.

Hi,

I'm sorry but i really am clueless ...
I installed the drive into my computer and ran DMDE.

The partitions now shown as:


I followed your instruction from another thread and copy the sectors of 0 to 3, 264192 to 264195, the last 3 sectors to bin files on my desktop. The 0-3 when opened with notepad has "Invalid partition table", the 264192-5 has"A disk read error occurred", the last 3 sectors has "EFI PART " ..., the rest i cannot read (font ?).

Can you tell me what else i can do with this ? As you can see from the table partitions there're Microsoft reserved partition and Basic data partition. These two im afraid were created when i installed it in the computer and let it run check disk. Suprisingly the Basic data partition has some files and folders from before its messed up, but not all (only a few files).

Thank you very much!

I don't have much hope though, now its like this ...

ISTM that all your data are still there.

I would examine sector 264192. That's the first sector of your data partition. It should be an NTFS boot sector.

Launch DMDE, uncheck the "Show Partitions" box.

Editor -> Goto Offset -> sector 264192.

That should tell us where to look for your MFT. If the MFT is intact, then you should be able to recover your data with the original file and folder names.

Any idea how close the enclosure has to be to the original? I have a 3TB external HD that just died and need to recover the data. This explains why I cannot get any of my data. My drive is about 2.5 years old...is it feasible that it will work in a new 3TB enclosure?

Thanks for the answer. After doing some addition research, I am going to try to find an exact match to the PCB which I believe is 4061-705089-001 REV AF. I think one that has a REV AG should would work. Which chip is the 8 pin firmware chip?

I have the same problem with a 3TB Wd mybook that i forgot to remove from a computer where i reinstalled windows XP. I used the Drive to backup data. When the partition was created using the recovery cd from HP, IT only showed one Drive, i erased it, clicked Next, restarted and that was it. Now I have a unformatted 400GB MBR partition and 2.7 TB unallocated. Should i remove the hdd and attach it to my desktop and use the DMDE program or leave it in and try using recovery software. I have to get the data back by tomorow, there were many Image files, made with symantec System recovery..

So I have WD MyBook 3TB HDD purchased in the year 2014 which first became available on AmzUK on the 22nd Oct 2013.
Does the data encryption affect the newer 2013 model range or is it just with the older versions of the WD Mybook?

Hey fzabka, Ive seen you post great advice! I'm in a similar situation, I had no idea the drives were automatically encrypted. I have a WD My Studio LX, and when I tried to clone it, or a generic enclosure it wouldn't show anything.

I quick formatted it to see a drive letter, but I haven't saved any data on it. If I can fix the broken USB on the original PCB, will my data possibly show?

Your a HUGE fzabkar help!! Thank you so much. I was able to fix the firewire port and use it instead. I can see all my original folders and names, with EaseUS data recovery and even recover some.

Is it away to recover my original partition, so my external will have a drive letter? All my files are in the right folders with proper names.

I am using EaseUS partition recovery but it hasnt found anything thus yet. Should I try complete disk scan with it?

@Ilovesports22, DMDE's partitions window is showing that sector 0 has no partition table (which is expected), but sector 63 also has no boot sector. You can easily "Restore the Boot Sector from Copy", but I suspect that there will be additional problems. In any case I wouldn't change the boot sector without examining it first.

You can view the current boot sector as follows:

Mode -> Hexadecimal/Text
Editor -> Goto Offset
Sector = 63
Sector Offset = 0
From Start/End
Dec

If you double-click $Root or "All Found + Reconstruction", then that should show all the files and folders that DMDE has found with a simple search. I suspect that you will only see a few files. If that is the case, then you could perform an NTFS Search on the selected partition. This will cause DMDE to scan the drive for NTFS related file system components. You can Start/Stop the search at any time and then view the results with Open Volume. DMDE should find the MFT and other file system components within a few GB. If you don't see all your files, then you can resume the NTFS search, provided that you have saved a log of the previous search.

I hate the kind of advice that basicly tell you that you are stuffed.. Just encountered the same problem when i changed two disk positions physically. The disk is a standard WD3TB green.
Guess if i shouted when i thought ive lost 3TB?? However i found this great piece of software and got away with just a hickup.
http://www.minitool-partitionrecovery.com/ <-- free software. It was easy to use and did the job in 5min.
No need to run a timeconsuming AND double the space requiring datarecovery program if you can just recover the partition info where it is.
No need to spend every day as if it is doomsday..
Hope i can make the day for some fellow computer users.. google did it for me.

I don't use MiniTool, but ISTM that it is intended for reconstructing partition tables. AFAICT it would be of limited use in the current situation since the boot sector of the first volume is missing. That doesn't appear to be something that MiniTool can fix.

Hey everyone,

I've encountered a pretty similar problem Strays originally had.
My 3TB WD MyBook Essential simply wouldn't mount a couple of days ago. I can't say why that suddenly happend. No physical shocks or falls, no (as far as I know and everything else on my system still works fine) voltage peaks or anything. I tried the drive with different cables on different computers but just couldn't get it to mount. The Power LED lit up, but that's about it.
So I opened the encasement, took the HDD out and plugged it to the SATA port on my PC.
The drive showed up in the Windows HDD Manager as an unidentified drive.I then did something terribly stupid, which is identifying the drive, setting it to GPT. BUT at least I didn't format.
So when I look at it now, it says "RAW".
I tried running a recovery tool, that after 9 hours of searching only spat out weird files - again as in Stray's case - jpegs, that are huge and where never on the drive for example
I've since learned, that the PCB seems to do a hardware encryption, which is why I couldn't recover anything.

This is whre I can't follow your advice anymore. You tell him that he could buy a new PCB, but since he trashed the partition table (as did I) he still would probably find nothing on the drive, even if the PCBs matched.
So should I plug in the drive via SATA straight into the computer and run DMDE to search for boot sectors, or do I have to connect it to the computer through a (matching) PCB?
Or are you talking about finding the (matching) replacement PCB without a HDD connected to it with DMDE to find some backup NTFS partition table?

I'm a little overwhelmed by the whole topic, so I'm sorry for any possibly stupid questions, that I'm throwing your way here.
But any help would be greatly appreciated!

@Fuchur86, ISTM that you should begin by confirming the physical state of your HDD. To this end I would connect it via SATA and examine the SMART report with a tool such as CrystalDiskInfo.

http://crystalmark.info/software/CrystalDiskInfo/index-...

Look for reallocated, pending, or uncorrectable sectors.

Next I would reinstall the drive inside its enclosure and confirm whether it spins up. If not, I would first check your AC adapter and then I would examine the USB-SATA bridge PCB. Connect the bridge PCB on its own and confirm that the OS is able to detect it. You can use tools such as UVCView or USBDeview:

http://www.nirsoft.net/utils/usb_devices_view.html
http://download.microsoft.com/download/e/b/a/eba1050f-a... 92cdfeae4b45/UVCView.x64.exe
http://www.users.on.net/~fzabkar/USB_IDs/UVCView.x86.ex...

If the bridge is detected, but the drive doesn't spin, then there is an 8-pin dual MOSFET chip which would be suspect. There is a relatively easy DIY fix if this is the case.

As for my previous statements, they do appear ambiguous. Sorry. What I meant to say was that, since the data in sector 0 (the partition table) had been reinitialised, then one would not be able to tell immediately whether the replacement bridge PCB was mismatched, in which case one could scan the whole drive and not find anything. That's why I suggested scanning for a backup boot sector at the end of the drive. This sector would not have been touched by the OP's misadventures and would quickly confirm whether the PCB was a match. Such a reverse scan would require only a few seconds.

Thank your for your quick reply!

I connected the drive via SATA and ran Crystal DiskInfo. It says the Health Status is "Good"


With the HDD connected to the PCB the drive won't spin up. The LED is lighting up, but it's not blinking, as it normally does, when there's some kind of activity.

I connected the PCB Bridge alone to the PC via USB and couldn't find it with UVCView. I tried a different (also from an external WD HDD) AC Adapter that normally works. Still nothing.

I guess this is the point, where I try to get a replacement PCB, right?
I'm in germany, so it might take while to get shipped here, since the only ones I can find are on US eBay or in Hong Kong.

Once I get the replacement PCB, I hook that up to the drive, connect it with the computer and hope it spins up and shows in Crystal DiskInfo, right? I then run DMDE to search for back up boot sectors at the end of the drive?

I'll report back as soon as I get the replacement PCB.

Thank you for your help!!!

I'm not sure whether WD's bridges all behave in the same way, but I have a WD bridge that flashes the LED and identifies itself via USB in the absence of a drive. However, I know that some non-WD bridges can be configured to remain silent when they cannot detect a functioning drive.

Many WD users report problems with the flimsy USB connector, so that may be something to check. You might also like to try a USB 2.0 cable rather than 3.0. These use different pins.

If you need to purchase a replacement PCB, I have been told that the firmware version has to be later than or equal to the one printed on the barcode sticker. In my example it is "Rev. AE".

I had no idea, you could plug a micro USB 2.0 cable in a USB3 port!
But unfortunately without any affect in my case here.
I also can't identify any faulty pins or connections of the USB connector on the board.

I ordered a replacement PCB on eBay the other day. It should arrive in about two weeks. If that doesn't work I could backup a WD Essential drive I have lying around, that's newer than the one that's damaged, pop that open and try with the PCB of that drive.

Thanks again for your invaluable help! I'll report back as soon as I have the new PCB!

No data recovery software will be able to recover even a single byte of your data ... until you reinstall the drive in its external enclosure. This is because your data are encrypted by the USB-SATA bridge firmware, even if you have not set a password, or explicitly chosen to encrypt your data.

Moreover, WD's 3TB My Books are configured with 4KB LBAs. When you remove the drive from its enclosure and install it inside a PC, you expose the drive's 512e LBAs. This means that sector 0 is still in the same place but every other sector is out by a factor of 8.

The original partitioning scheme was MBR, not GPT. A 4KB sector size allows for a maximum MBR partition size of 16TiB whereas the traditional 512-byte sector size limits the partition to 2TiB.

Hi Fzabkar, i have the same problem, my ebook Essential 3tb i can go into my data, its supossed to be there but i cant access, light is blinking. I already download the drivers and reinstalled and nothing change, i cant recover from any recover program because it doesnt show me the disk, I dont know what to do maybe you can help me, i will aprec

@Ekattan, you need to first determine whether your drive has physical problems. To this end I would examine the SMART report with a tool such as HD Sentinel or CrystalDiskInfo.

http://crystalmark.info/software/CrystalDiskInfo/index-...
http://www.hdsentinel.com/

Look for reallocated, pending, or uncorrectable sectors.

You may need to do the above with the drive connected directly to a SATA port on your computer's motherboard.

ok, i downloaded hdsentinel.com and his is what it shows me: performance: ? Unknown Health: ? Unkown The status of the hard disk is unknown.
This USB storage device does not provide more information about itself. Anyway, it can be tested for problems by Disk -> Surface test function.
