I've never used this stuff, Joanne, but I know people who have, which

You may have to specify "--user-master m --set-security-password
thepassword --security-mode h" to actually set it, and if it's already
set, I don't know that you can change it. You could try "hdparm
--security-help" for details on what it expects.
As all of these commands are considered "dangerous", I'd only play with
them on a drive you can afford to turn into a doorstop or paperweight
if things go wrong.
It seems that setting the master password is not possible.
Why is that?
Could it be that the command itself has been hacked
NOT to change the master password?
Time to take a look at the source code :)
Yup. I did take a look at the page Chris cited and it does go into
things fairly well and describes the master password issue. Yes, all
examples are in "user" mode, but if it does the job then I don't really
see any need to go deeper (except to satisfy any morbid curiosity
streak you may have).
