Hello guys

it's the first time for me in this forum, I hope that you can help me to solve my issue.
Let's explain which is my issue:

Seagate ST500LM000 with Security ON HIGH Locked, the ATA password has been forgotten and the data within the SSHD are very important for me and I do not have any backup of it.
So it means that I'm desperate

I bought SeDiv tool but unfortunately this specific model is not supported yet.
I "built" a serial cable in order to connect via the diagnostic port and I found the diagnostic commands...but it is not enough to accomplish the mission.

Can someone help me in this hard mission?
Please let me know if my request is clear or if I have to explain better the situation.

Thanks a lot in advance for your cooperation and support
ciao

ciao

Thank you so much for your support Spildit,

just to understand and to learn something else
do you want to share with the forum what you did?
The Master and User password you set it is not possible to see, simply translating from HEX to ASCII I think...

In order to "upload" or write back the sysfile, I think it is enough to w30A, isn't it?

Thank you again
ciao

Ok Spildit,

I compared what I downloaded from the hard drive with what you modified and:

on the address 00000048 you modified 00 00 00 00 12 02 00 00 0C 54 01 -> 00 00 00 00 12 02 00 00 0C 54 00

the "famous" field involved to enable or disable the password, is it correct?

ciao
gio

That's it. The same way you read it.
Good luck

Issue fixed! Thanks a lot Spildit for your essential help

I understood what you did, just a recap:

1 - download, from the sshd firmware, of the 30A memory address (r30A from T level)
2 - editing of the field involved to enable/disable the "Security option" (using a binary files editor)
3 - write back the code to the same memory address (w30A from T level).

And until now for me is clear, what I don't know is the following:

1 - How did you know that the memory address involved in this particular issue was 30A ?
2 - How did you know the specific field and HEX address to be edited ?

Could you please help me in order to understand?

Thanks a lot again
ciao
