Потерянный пароль жесткого диска. не может заставить hdparm заканчивать его

Я имел этот ноутбук в течение 3 лет и просто решил смешать с паролями BIOS, и я поместил пароль в свой HDD. Именно так происходит, что в течение пары дней после наличия статьи обо мне с моим паролем, я теряю это и отдел, я забыл делать резервное копирование.
Я использую hdparm, но у меня нет удачи.
У меня есть спутник Toshiba P75-a7200. HD запаса, если это помогает.

Я вставил эту строку.

sudo hdparm --user-master m --security-unlock "                                " /dev/sda

ниже вывод:

Та строка является попыткой предназначаться для основного пароля по умолчанию, который является, по-видимому, 32 пробелами для Toshiba, но никакой удачей. Вывод похож:

/dev/sda:
 Issuing SECURITY_UNLOCK command, password="                               ", user=master
SECURITY_UNLOCK: Input/output error
