Formatted WD50NDZW

[saltwater]

Hi there!

I have a case, and i need some confirmation.
My customer formated his drive, and now all sectors are zeroed.
I have saved the 190 module, in MRT T2 editor searched for all nodes, and all rebuilded T2 RAW files resulted 0GB valid data.

So please somebody could confirm me that, this formatted drive is not has any recoverable data?
...or if somebody can create T2 Raw data file that has any recoverable data, please attache to comment.

The packed 190 module is attached.

Thanks for any help!

Common scenario these days

I guess i could do it, at least for raw rec...

As I understood, it depends from was SED turned on or not. SED also depends from the sector number (LBA) and when new T2 created (for RAW scan) physycal sectors have new logic number. That's why the decryption produces white noise enstead of real data.

I read out all SA modules over USB, so in this case the decryption is not matters i think. I still use original PCB with this drive.

But now i got a formatted Venicer drive (new case), and after i created new T2 raw file, i see the WD main program says there are 400GB data, but uploading the new T2 raw file to memory, there are still all sectors are zeroed.

before doing experiments i had same oppinion but i was able to read correctly decrypted sectors so i definitely think pba is used for seeding.

PCHS reading with ignoring T2?

do i need to answer that?

hello,
it seems like i have to admit i was clearly wrong with the upper statement, SED was OFF on that drive i got those results.
i felt confident that all SG drives have SED on :s
sorry
