SEAGATE: Non Standard ATA Master Password

[Buldo]

Hello, I also have 2 hdd Seagate ST3250312CS (old tv decoder). I make the cable RS232 (MAX232 thank you). In order to use these hdd, remove the password. I understand the principle:

Vendor to Track Seek, Read Track, Copy Bufer Read to Write Buffer, Edit Buffers to First Byte 00, wrote the buffer back to the drive.

With SeDiv, I can not find Track Vendor, the address buffers reads and write.

If a charitable person could help me, I would be grateful ...
Sorry for my English (thank you goooogle)

Ok, ty Spildit. I had found the information in the meantime into the file called "seagate diagnostic command.doc"
I was trying to understand this sequence of command her:http://forum.javaxtreme.com/threads/103-Seagate-Diagnostic-Command-List?p=1958&viewfull=1#post1958
i think i got it for the main part.
I still wonder exactly why there is second argument (which is supposed to be the write buffer 40D)...

Im currently trying to download the different modules as explained into the this file, into T level:

Code:

uxx Upload CERT, RWF, CSPT, DEF from Serial Port to Buffer then write from resv

Performs the uploading of files from the reserve tracks. The keys are exact the same as those in the download command.

Code:

When trying to do that each time i got this response:

Code:

T>u1
Command Inactive - No VALID Cert Code Detected


Is this the command supposed to be used to get the different modules of the system area?
Sorry for the maybe noob questions, i'm alone as you are Spildit.

I still wonder exactly why there is second argument (which is supposed to be the write buffer 40D)...

To write the "edited" data back to disk.

Addr 0 1 2 3 4 5 6 7 8 9 A B C D E F 10 1 2 3 4 5 6 7 8 9 A B C D E F
081A00 01005365 61676174 65202020 20202020 20202020 20202020 20202020 20202020

In RED you have 01 (password locked) and you want to change it to 00 (without lock) so instead of figuring out the password you edit the address on memory

1>U81A00

Adr 81A00 = 01 --> 00 {Shift+Enter = Save and Edit byte again}
Adr 81A00 = 00 --> {Ctrl+Enter = Save and Edit Next byte}
Adr 81A01 = 00 --> {Enter = Finish}

From 01 to 00

And then you write it back from memory (buffer) to disk (platter).

When trying to do that each time i got this response:

Code:

T>u1
Command Inactive - No VALID Cert Code Detected


You have to load Cert code first !

CTRL+R on terminal will load CERT.

Sorry but i mean why there is NO second argument in the line:
C3FD,,10
The second argument is supposed to be the destination, buffer, and the manual does not say what it do if you dont put it, by default it is the write buffer?
About the No VALID Cert Code detected, i've tried everything with no solution. CTRL+A CTRL+R and also /1 level and the "r" command. Nothing works.
See by yourself:

Code:

T>u10
Command Inactive - No VALID Cert Code Detected
T>Eng Rev = .0E1
TONKA2 - 1_Disk    3.ADH  02-08-06 16:13 ADH,1H_S_013_M1,4T
CERT Rev = .0B8
.0B8
Mask Rom Rev = M-31
Unique Descriptor = .3M1

T>/1
1>r
VALID Cert Disk Code Detected - Revision # .0B8
1>
1>/T
T>u10
Command Inactive - No VALID Cert Code Detected


The drive is a seagate 7200.9 ST3808110AS. Regards

I had the manual thank you, did you read my last post? I just dont understand why the upload module from reserved area, does not work as seen in my example.
By the way, do you read your PM Spildit?

Hi

Did you ever find the solution to this?

Looks like you are using u instead of U. Commands are case sensitive.

Cheers
