Loooool. Ehh, servo error's in scan D1, and limits full. Still I am not sure whether the script is , however, servo . Log attach tomorrow.

Hello everyone, sorry for my poor english, because i using google translator.

Can you show us the contents of module 02 before and after unlocking?

Yes, And there are some differences, and not just one byte.

Hi
There are many many types of locking in wd 02 modules. Sed lock. Sector read and write disable (for dvr hdd). Dco lock. Etc

Yes will upload picture of 02 after and before for sed locked drives. For dco unlock i think pukius upload 02 module.


Every wd family have different location of byte which we need to change for unlock. But the design and structure is same. Only location of byte goes on high offset and some time low offset.

Well, I preferred to attach the module unlocks the original before and after unlocking.ok thanks for suggestion.

Aside from the model and serial number sections, I found the following differences:

section 3 - Feature Control


section 13 - Background Configuration


section 14 - CDD Configuration


section 27 - ??? ("slow fix" section)

Yes, because 02 before unlock is in oryginal backup SA,
no changed, but After unlocking 02 preparation for ARCO, slow fix and test B2

Hi
Here is the modules for SED lock and unlock for Firebird hdd,

Editing will make data recovery impossible , because it change the reading method of a sector.

must save the original 02 module if you need data, or after edit 02 for drives repair, convert the 02 editing to original position.

Ok, Thanks for suggestion.
But Self test, Test 1003 - shows error 7000 Servo PTM_code Base 704F, then self test stops, and not continue, checked in 10 scripts, but problem the same.

Hi
Remote ammy admin id please, PM me remote ID

It appears that section 31 is not the relevant section. Instead it is section 32.

SED locked


SED unlocked


The relevant section of Mod 02 is section 32, not section 31.


Section 32, offset 0x71F, size 0x7 bytes

Hi fzabkar.
I didn't understand what you want to say.

You need to change only one byte from 01 to 00 to unlock.


I not understand you means by section 31 or 32 and 7 bytes.

Waqas ali

Waqas ali, you need to understand the structure of Mod 02. Then all will be clear. It makes no sense to refer to absolute addresses within the module.

Hi friends Calmly I checked wd Black and probably has damaged the second servo . Heads 0, 2 , 3, 7 in the user area sequences have bad sectors and which may be interesting for this test does not pass the calibration selftest. Understand me?

Hello everyone, sorry for my poor english, because i using google translator.

well no one have time to learn in deep, only the address is good for every one, just change and do a work, thats it.

What is in back ground of 02 and structure of 02 module is a work or researcher or software developer.
normal person don't need this thing. he just need to do as quick as possible.


But in real your theory about 02 is 100% real and perfect.

@waqas_ali766, Firstly, let me say that I am grateful for your information. It was very enlightening. However, your initial post was confusing and misleading for several reasons.

Firstly you stated that one needed to change the following data set from ...

01 D6 06 00 1E 00 00 00 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 01 00 01 00 09 0F 0F 0F 0F 0F 00 00 00 00 00 00 00 00

... to ...

01 D6 06 00 1E 00 00 00 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 01 00 01 00 09 0F 0F 0F 0F 0F 00 00 00 00 00 00 00 00

In fact the two data sets are identical.

Then you stated that "you need to change just one byte from 01 to 00 at offset 725". Clearly there are several instances of 0x01 in the data set, so it is not clear which byte must be changed.

Furthermore, your reference to offset 0x725 does not clarify your instructions. Worse still, the Hubble_LT resource which I downloaded from HDD Guru differs from your own, so this means there is no consistency even within the same family.


The only consistent fact appears to be that the SED unlock byte is located at offset 0x06 within section 32.


Here are the relevant data for section 32 in the index:


As you can see, section 32 has a size of 7 bytes and is located at offset 0x7A1.

If we apply similar logic to pikus_09's 02 module, we find that his section 32 is located at offset 0x611.


Furthermore, the surrounding data differ significantly from your example.

Demm, nice suggestion. But at this time I don't know what is, because Sediv software for me locked. I can't run execute SA calibrator, or selftest. Nothing was change. Always Reset impermentiale and nothing.

Hi fzabkar
i told in my previous post that the location of SED locked Byte vary on different families.

on Hubble_LT SED locked drive offset is 725, but in non-SED drives you will not find this byte and this sections of SED lock.

May be you download non-SED drive 02 from internet that why you get confuse.

Also some DVR drives which yous Port locked, also unlock by 02 module, but the offset which you need to change is at different location.

Some drives SPECIALLY denali become read only, you cannot edit any module of any other thing, this also because of 02 lock.

And in Pikuis case its Mantis Drives, Mantis and some more families have Issue, Hdd cannot Start format SA, and shows DCO freeze lock, this also because of 02 and some thing in ROM.

There is many many secrete in WD 02 module.

also the latest drive may change the user data by editing 02 module. same like Seagate SID drives, in Seagate SID drive if you use Z0,0,22 then the Seacos encrypted sector will be removed, and you get permanent access to terminal. now you can recover the data, once you edit any of user data sector then you will loss all user data.
Because after editing the sector , hdd write it by encryption, and when you read all byte of same sector goes in to garbage shape, because the decryption key is erased. (Seacos SID key) , the Key is always written on the HDD sticker, some one have to make a software to clone all sector of drive using the SID key, if the data goes garbage.

After that you cannot use this hdd in pc, because the hdd have encryption sector and not have decryption sector.

then you have to LOAD LOADER with winfof to update the firmware, also you can use Seagate firmware update.
after firmware update, like in my case hdd have FW=0003LVM3 anf after Loader write with Winfof the firmware version become 3LVM1
i attached my loader you can download


Its not easy to work with Latest drives, they are making it more and more complex.

Picture of Seagate SID self encrypted drive


you can see the SID key
Will upload the picture of Data sector soon, what happened if we remove the Seacos Security sector and AT overlay.
