In hddguru resources none of Samsung M9T (there are two 2TB : http://files.hddguru.com/download/PC-30 ... 101205.rar, http://files.hddguru.com/download/PC-30 ... %202.5.rar) has capacity string inside PROFILE mod (nothing like B0 88 E0 E8 or even 88 E0 E8)

True, but the following two parameters in your PROFILE module don't appear in HddDonorMarket's PROFILE module, either. So it would appear that some parameters are "optional". Maybe the parameters in the PROFILE module override similar parameters in other locations ??


BTW, the first parameter has a value of 0x30 which corresponds to the capacity reported by your drive when it identifies itself as HN-M201RAD. Also, the second parameter is the max LBA in 28-bit LBA mode (0x28 = 40 = 41 - 1). These could be coincidences, but they do look suspicious.

Can you access sector 0? If so, does it look like an MBR?

The PROFILE module is updated whenever there are changes to the drive's configuration. For example, if you set an ATA password, there will be a new "3322" parameter in PROFILE.

sector 0 - all 00

Is it possible that this drive has been sabotaged?

Have you tried replacing the PROFILE module with the donor?

Have you checked whether the modules on head 2 match those on heads 0 and 1?

Note that the PARAM_DM module incorporates a defect list, so it is unique to each drive.

I've already tried replacing PARAM_DM and nothing changed.
I'll hopefully try with PROFILE this weekend
Yesterday I found this post: https://forum.hddguru.com/viewtopic.php?f=28&t=31039
if I have time I will try on the weekend. In the beginnig I checked hpa in MHDD. There was one, but set only for 2-5 LBAs (now it reports 6 LBA).

... 'sabotage' is possible becouse previously it was diagnosed in other DR company and the customer decided not to recover.
I've already seen several such cases ('sabotaged') from reputable companies.

AFAICT, you can disable the 2 suspicious parameters in your PROFILE module as follows:


This reduces the total parameter count from 0x4A to 0x48.

Have you ever tried with another PCB ( as my tried . I ve got all data with donor pcb parient PCB was look like ok. )

Changing from 0x4A to 0x48 in PROFILE module gives 403 019 726 LBA (192,2GB)
LBA'a are 4K only, so it's a clearly more than 1.5TB

How did you figure it ?

... changing to 0x49 or 0x45 gives the same result (403 019 726 LBA)

The PROFILE module consists of several records, each of which defines a particular parameter.

Offset 0x10 is the total count of parameters, while offset 0x12 is the space occupied by all parameters (x 0x10).

Your PROFILE module has 0x4A parameters, and they occupy 0x4A0 bytes. By changing these numbers to 0x48, we are effectively ignoring the last two parameters.

The layout of each record appears to be as follows (the terminology is mine, so it may be incorrect):


In your case there appear to be two additional parameters in group 0x22, and these appear to contain HPA data. Our edits to the parameter count have told the firmware to ignore these extra parameters.

Spildit and I have done some work on this module here:

I suspect that the donor PROFILE module should fix your drive.
