Model no: ST980811AS, locked in high mode.
Master password "Seagate+25spaces" does not work.

For this case u need a tool wich managed access to the Engineering Cylinders the SA , another public soft its not possible because are negative tracks, then read the modules and modified some bytes, there are not another option.

Best Regards.
