Hello Everyone ,

The HDD is Question is This



The customer says his kid dropped the hdd ,I do not remember if this HDD would click or the PCB would just not spin the HDD and get into ready state .Anyways yesterday i took another HDD of the same family and swapped heads .I would like to inform all of you that beware of these HDD's ,I have seen these in the following combinations

1 : 2 platter 4 heads bottom platter and heads missing
2 : 3 platters and 6 heads
3 : 3 platters and 5 heads with lower platter lower surface head missing

So the utilities from which we get head info are all misleading example it says heads installed 4 used 4 ,We assume lowest platter to have 2 and one up to have another set of heads making it 4 ,But it could be lowest platter is missing and we have middle and top platter used .I took the ROM Code out from the patient SED locked board using a programmer and programmed it on unlocked board using PC3K ,Board No is 8.....11 .Once powered on the Status registers in PC3k would go busy and immediately get ready state ,The HDD would not spinup .I have seen this happen in some other case also which i had done .The ROM is Attached To the post for anyone of you to analyze and help me .The file is renamed as a .zip though its .bin . Anyways i just though why not try ROM of the HSA donor HDD ,I programmed it into the ROM of the unlocked board and the HDD spinned and i was able to access all modules and even data .The data looks encrypted .I then programmed the DONOR HSA HDD Rom Code into patient ROM and resoldered it into the patient SED locked HDD PCB .The result was same Data is encrypted .Does a ROM make a difference to data encryption ,I do not have doors to work on these drives but i was having a though might be decryption keys are in MCU " Not Sure Though " thats why i tried Patient PCB . This is a External Casing HDD so i though might be the USB board has encryption ,I then used DONOR HSA HDD ROM programmed into Patient ROM and This ROM installed on patient Board with The WDC 3.5" USB To SATA Board on Deepspar Imager ,Result DATA is encrypted . I tried several other things which i will post in the evening possibly to this thread , Donor ROM is also attached to thread as .zip File .BTW both ROMS are different Versions

Some Stuff To Try

1 : Using DONOR ROM and Shifting All Modules of patient ROM to it and See if this works
2 : Trying to Retain the Modules of the ROM and Changing Code Segments
3 : Checking SA to See if ROM can be regenerated
4 : Working on Module 0x129 thats hidden In DIR module and has ROM Modules in Venice R - > https://www.youtube.com/watch?v=WK2P9p6Mf7s&t=2806s ,My Idea was not to unlock but extract ROM modules from 0x129 .

Am i on the wrong track ,Can you folks help me in this case please .How to defeat this encryption .Any Indian DATA Recovery friends who would like to advice me can call me on 9 8 1 5 0 0 0 1 3 3 .

I would use original unlocked ROM / original PCB and let DE take care of USB bridge encryption if pressent.

Noted ,
In My case there is no spin with original rom and original pcb , so de is out of the question ,BTW sometime DE does not work with encryption of bridges
in rare cases

Ahh understood. Then you need to repair pcb or transplant MCU to working board. Else outsource to someone who can decrypt MCU encrypted data.

Well,
Nothing is wrong with my patient board other then bad rom code or modules IMHO , Please read my initial post once to understand my issue

Well,
This i Agree ,But the problem was totally different ,

PS : So if any of you indian data recovery guys have a issue like this let me know .

After T2 Loaded all Data comes with encryption. Can u guide me to recover data

Make sure mods 0123-0127 are ok. Data will look encrypted if not. Had a recent case of one of these drives from a MyBook with SED lock. Had to create smart donor because of media damage on patient and gained sector access but was encrypted.
I learned data was not being encrypted through USB bridge--had Asmedia bridge chip. Found that 3 of the above mods on my smart donor were empty (or hadn't moved them in the first place). Was able to read them again from patient. Moved them to smart donor and had unencrypted data via SATA connection.

125 126 127 are same for all hdds. 123 and 124 differ. In my case there are some keys values in 123 and 124 but getting only encrypted data

What model of USB box has been used?

WD MyBook Actually just received HDD only

Attached Some Key Modules

USB bridge board chip is ASM1151W

Case Solved. All Data Recovered.


If i solve another case successfully i will post my soution

Well,
Do Not Keep it To Yourself , They never release thier solution ,We will share as always .

First asked u Mr. Amarbir Sir through PM , Post and Whatsapp but no reply.

So i tried myself and got result but it may not applicable to other case. So only i posted if again succeed in another one case i will post what i did
