Previous post would miss a step, after solving the slow problem you should enable the 411 module again.

A tip, do only these steps (or others that indicate you here), your knowledge of DR is very limited, if you do experiments with MRT/WDmarvell, it is possible that your client's data ends up in the trash can.

Send the drive to someone is spain with more knowledge for a fix ?

I wouldn't do anything like you are trying to do. I would short E47 with GND on your SATA PCB and power the drive up. Remove the short and try to initialize dir and load overlay to RAM. Then i would try to read all modules and back them up. If SA access is possible i would patch module 02 and check possible SED flags, etc ...

Then i would re-power the drive in normal mode and use DE to deal with the decryption. Alternative would be to attempt to place the natice PCB back. Also make sure that your SATA pcb does have the ROM code from the USB PCB copied to it.

Thank you very much to all for your help, with which I have verified that the family is fblite as you have told me and I have learned a very important thing isolating the motherboard and detecting in kernel mode the family.

Heads number : .................................: 0x4
Heads number in use : ..........................: 0x3

The initial problem of the disc was a blow while it worked. The heads are fine, I've tried them on another disk and they work, but the plates are a little marked just outside.


Uff, hard case.........

Previously you were able to identify it in kernel mode. Follow the same steps (isolate PCB or short-circuit TV9-TV10 until you reach it) then follow the steps above or manual loading as indicated by spildit

If you can't get the disk ready you won't be able to apply them.

mhp666, I would like to know the answer to a question (and no offense)

You spend $3,800 +/- on a tool and don't know how to solve a slow response problem in WD? why?

Maybe he does have a On-Line version ... ? And aparently he can do head stack replacements .... Strange ...

I have the mrtlab online.

The hard drive I'm trying to recover is to do a favor for a friend who does not have the money to pay for a data recovery.

And I'm trying to enter this world, but since there is so little information, I'm gradually making my manuals.

I have done practices deleting and recostruyendo the SA of HDD. But I need a little more time.

Greetings.

Excuse me, but I don't understand anything,

You say you did practice removing and rebuilding SA from a disk and don't know how to get to kernel mode on a drive (WD)?

How can this be?? So I guess I'm the one who missed a lot of classes......

Your friend, sooner rather than later, will regret putting the drive into your hands.....

Do you have any practice at all with head stack replacement ? Are you using HEPA 100 aseptic room or laminar flow workbench ? If so can you replace heads from drives to drives without any issue ? Are you doing that for at least one year or so ?

If we can confirm that your head swap was ok i might be able to help you out to fix the firmware side of the "problem" but again this would be ONLY if i were to be 100% sure that the head swap was properly done and you didn't mess it up big time because if you did i will not be able to "rescue you" as i don't do clean room work ...

The dishes have scratches as shown in the picture. Right on the periphery.
I have not removed the plates to check the lower ones yet.
I'm looking at how to make housings with transparent slots to see the movement of the components. I'll show you already.

Better a garbage can to throw away all the drives that pass through your hands......

It'll be more useful.

I have placed the heads of a disk wd10jpvx.
The reading speed is very good.
It still gives me problems but I will continue tomorrow. I give you an image.
Colanco If what you pretend is that I feel bad. You've got it.
Greetings.

MRT can easily solve the problem, and you will also need DE to deal with the damaged areas.

If you have the latest version, enter again in kernel mode and disable the 411 module ( if you have this model)---> off/on -----> identification in normal mode ----->>(already automatically loads module 11) ------> solve slow responding problem -----> off/on -----> ok.

If the model does not have a 411 module, you will have to load module 11 by hand, you have many options, but believe me, it is simple, it is done daily (1st week of the first DR course).

Then you will have to deal with sectors and encryption (if you have one)....


Totally agree, and do not remember to enable module 411 in the end :)

PList seems to be correct.
But the ZONE ALLOCATION TABLE is wrong.

For Western Digital hard drives, it often appears the situation that disk can not be ready due to long time busy status, or the disk can be ready, but when there is a data interaction, the disk turns into busy status and can not be ready again.

The conventional method is to close the entry of system area or add defects to system area, and then load LDR to obtain the normal reading and writing access; What's more, we can also use "Disable 02 module" function to obtain the reading and writing access of system area. However, these methods have their own limitations. For example, sometimes it is difficult to find needed LDR; On many new models, "Disable 02 module" function can not effectively obtain the reading and writing access of system area. And this is the time we need to use our new function of "Disable 411 module", using this method to repair new Western Digital hard drives' firmware problems can be much more effective.

@colanco Seems you have already used our new function of "Disable 411 module", which is really easy in operation and powerful in function;

@mhp666 http://en.mrtlab.com/disable-411-and-02-module for your information, and any technical issue, please feel free to contact our technical support. And we have online training and real-site seminar to help users to master disk repair and data recovery, if you are interested in, you can contact us.

I explain the steps of firmware that I have made.
I remove the HDD PCB.
power on -> disable module 411 -> power off
I put the HDD PCB.
power on -> Resolve slow response -> power off
power on -> enable module 411 -> power off
Correct detection

In my case if I did not remove the HDD board, I could not deactivate module 411, I preferred this to the short circuit, since with the isolated PCB it managed the ROM modules without problems.
