I'm sorry, I don't know the details of the ATA locking mechanism. (I've been content to simply rely upon my BIOS.)
I would personally not try to change the password while a filesystem on the drive is mounted, though I cannot articulate why I would worry about it. If you can umount the filesystem, I would expect that to be sufficient to allow you to change the password. Probably the drive must be unlocked to change the password, that would simplify the design of the drive firmware. I'm curious, if you learn more, please do report back. :) Thanks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1245255 Title: IO-Error when trying to change the master password of a self encrypting ssd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/hdparm/+bug/1245255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
