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.
