Slow responding WD20NMVW-11AV3S2

[D_R]

Hi,

I've got a slow responding WD20NMVW-11AV3S2. The PCB is 2060-771961-001 REV A. What's the best way to recover Data von this HDD?

I think, there are two ways. The first one is to solder on some wires to the PCB to get SATA connection. Another way would be a board swap with U12 swap.

But AFAIK the Data on the WD Drives is encrypted. How to deal with it? Swap the PCB again, when I fixed the slow responding problem with PC3k?

"Swap the PCB again, when I fixed the slow responding problem with PC3k?"

Sure, or decrypt using DE or ReallyMine.

Sure, or decrypt using DE or ReallyMine.

Ok.

I see, that PC3k DE has this feature. Thank you. That's my first encrypted drive.
I ordered the 2060-771960 PCB and hope, that this drive is going to work

Did you try using Hddsupertool? Some of these 2tb WD drives have their system area locked and it won't work, but I have successfully used Hddsupertool to apply the slow fix to a few of them.

[D_R]

Yes, I tried. But I can't get access to the drive.

I think, there are two ways.

have you tried using terminal in pc3k ?

[D_R]

have you tried using terminal in pc3k ?

not yet. what do I need to connect to the HDD via terminal? I have two pins on one side and 12 on another side of the USB connector. What adapter do I need to connect it to pc3k?

[jermy]

The same adaptar you use to read the ROM

Pic taken from data-medics.com, thanks goes to him

[D_R]

Ok, I've got the ROM data. But I still need a donor PCB to write it on. Or did I missed something?

But now I can do it without soldering

[jermy]

Who said anything about reading the ROM data
I asked if you have tried to apply slow fix WITH the USB uning terminal

[D_R]

Ok, I connected the drive with the Terminal Interface. Now I can access the SA.

But it seems like there is another problem with this drive. It seems like the P-List and the Translator are damaged:

I tried to read the P-List and get this error:

Code:

Defect list reading
Table................................... : P-List
File.................................... : <HDD Profile>\Defects\PList2.chs
Defect list has damages in actual data area


But if I try composite reading, I get the P-List.

What can I do now?

[jermy]

First backup all resources. (Using terminal will take awhile doing it)
then check other copies
If its SA problem, you'll have to transfer the mod to another location

[D_R]

I have backuped the HDD Resources over night.
I read the Translator (Module 31) from Copy0 and Copy1 and replaced the "DEAD" Parts of one file with the parts from another (Zeros). Then I checked the Checksum and it was OK. Then I moved the 31 Module to another location and wrote the merged data from the damaged Modules back.

I did the same with the P-List.

But I still can't access the data. If I connect the HDD via USB to my PC, the drive gets recognized now, but I can't read any data.

Using PC3k via Terminal and Sector Edit I get "DISK DAM ERROR". I also tried to activate the "Decrypt" function, but it also didn't worked for me. What can I try next?

Hi,

I have the same drive... wd20nmvw-11av3s2
I can still copy data at a few hundred kb/s.

I have watched a few videos about the slow fix and used hddsupertool to backup 02 and 32 but since I dont own PC3000 or DataExtractor, even if patch 02 and 32 I won't be able to decrypt the data, if I manage to actually image the drive afterwards.

In a similar case I had before, I sent the drive to Helpdisc in Serbia, but is it really worth it this time ?

Is there anything a normal user can do, that you could recommend me to do ?

Thx in advance.
