The user and master passwords have a length of 32 bytes. I wonder if these are the encrypted passwords?

Code:
Offset(h) 00   02   04   06   08   0A   0C   0E

000000B0            0F63 0D24 66E1 76BD 36A8 C628
000000C0  2825 C963 817F 79E6 2DF5 48C6 640C 58C6
000000D0  4A06 E425

Code:
Offset(h) 00   02   04   06   08   0A   0C   0E

00000140                 3958 3B06 C09A 9566 0447
00000150  F82F 4943 AA71 32EF 2E22 9F00 7FEC 7826
00000160  EB36 602F B91B

Can you experiment with a donor drive and compare the sys file before and after setting a known password?

If you set the same password on two donors, does the sys file change in the same way? If not, then there must be some key or salt that makes them unique.

Thanks a lot for your input Mr. Franc.
I did really an experiment with a donor drive with a known password set by me.
I found a lot of differences before and after in sysfile 30A in several places, and I didn't see the password Iput.
I will upload both tomorrow as I'm not at the office now.
Appreciate your help.

I guess that the password is encrypted. If the same password produces different encrypted results on different donors, then I can't see any solution.

Edit:

Do you know the master password? Perhaps you could replace the encrypted string for the user password with the encrypted string for the master password, and then use the master password as your user password?

This one tested and it's unfortunately true.

Assuming that you have set a user password, I think this is the master password in the donor:

Code:
Offset(h) 00   02   04   06   08   0A   0C   0E

00000060            22CD FCE1 6D60 2297 0B2E 8E18

000000D0  9B0A DCA5

Master password in patient:

Code:
Offset(h) 00   02   04   06   08   0A   0C   0E

00000060            BCFB BBC5 654E 4034 0ABF 2B8D

00000080  0000 0000 0000 0000 0000 0000 0000 0000
00000090  0000 0000 0000 0000 0000 0000 0000 0000

Perhaps you could paste the user password area from your donor into the patient? Then maybe you could unlock the patient with "Ahmed". This area comprises a 32-byte encrypted password plus 28 unique bytes that may be a salt or key of some kind (I'm probably mangling the terminology because I have zero experience in this area).

Didn't work.

I believe it's not that simple.
However, I wonder this is my first case seeing a Rosewood drive locked by ATA password after all this years.
I didn't expect to be that hard to unlock like older families.

Anyway, I do really appreciate all your help and assistance Mr. Franc.

Maybe there is a flag that indicates when a password is set, in which case the solution could be as simple as resetting the flag.

Have you tried copying the entire sys file between two donors? If this doesn't work, then there must be some additional security related firmware component.

I wish it was that simple Mr. Franc. But I don't think so.

Yes I did and still locked no luck.
Agree that there's other sysfiles related to security system, not only 30A.

I wonder if anyone have PC3K confirm that there's no solution for that case ?

Is there any difference in 0x1d1 and 0x1d2 in your donor before and after setting a password? I recall a post where someone said that MRT "unlocks" a drive by manipulating 0x1d2.

Sorry, I meant sys files 0x1d1 and 0x1d2.

I think I found interesting stuff in 0x1d1 in patient drive.
Tomorrow I will post from donor before and after setting pwd.

Please take a look :

These are already stored in sysfile 30A.

Maybe I should patch 30A and 1D1 both from donor to patient ?

I appreciate your efforts Mr. Franc.

I would first experiment with your donor. I would dump 0x1D1 and 0x30A before and after setting a password on your donor. Then write back the unlocked versions of both modules to your donor. If this unlocks the drive, then we know that these are the only modules involved.
