Help with unlocking ATA Password on Seagate ST3500312CS over serial co

[odysseus0303]

Hello,

im new to here but since u guys use the serial interface of a seagate hdd to repair it i hope someone can help me.

i have a Seagate ST 3500312CS "Pipeline HD .2 " that is locked with an unknown ATA Password, and the master password was changed too.

The drive was installed in a DVR (digital video recorder) , it is a 500GB 1-platter one (must be silimar to Seagate 7200.12 ?. it is a F3 architcecture)

i was inspired by this topic on another forum, but obviously the things mentioned there arent very beginner-friendly.

http://forum.hddguru.com/seagate-st3500312cs-equiv-t20805.html

so i now have a working serial connection to my HDD and basic commands (spin up and down ) tested working.

now can anybody help me how i get rid of the ATA password or how i can read it as in the topic described ?

i dont care of loosing data, theres just video recordings on it.

Not even "slightly-more-advanced-user" friendly (if I can be .consodered in this category)

What is written there is just "RTFM"!

What may be useful could be this list of commands:

seagate diagnostic command.rar

Seagate terminal command - unknown source

And the actual manual (I presume this one is the one for your disk, but as always check and double check):

http://www.seagate.com/staticfiles/support/disc/manuals/ce/Pipeline%2520HD%2520Series/100529372g.pdf

I have NO idea if what you wish to do is possible at all and/or if the aboive given files contain enough data to perform it.

Would not using hdparm work on that disk?

thanks i was studying the manual with the commands for hours now still cant figure it out.

i believe its possible , the guys there just dont want to tell.

as far as i know no software can crack a unknown ATA user password and a changed master password .

Well no, there is software, only most probably you won' t like it's price tag:

You can try also with SEDIV, see here:

but cannot say if that drive is supported in any of the above mentioned tools.

thats the problem the drive is too new to be supported .

even hddunlock.com cant do it because of unsupported firmware.

so i really need to do it with the serial connection and the command line.
