Every time I turn on my laptop it always asks me password and I have to enter it to use my SSD. I do know my user password but I forgot Master password. Please tell me about current state of SSD (frozen/lock) I really don't know anything about these terms. Please help me to disable Master password.

According to Samsung Magician, Class 0 security enabled
I have backed up my data and now ready for a full wipe

Select "Change User Password" in the BIOS screen and disable the password. That's all you need to do, AFAICT.
