Could use the help with locking it back up

[ptspawn]

Hi,

Sorry for the inconvenience. I'm using your script to unlock my WD in a script, but i also wanted to manage to lock it back up when I needed. Since I don't really understand whats going on with sg_raw apart from sending an hex code which I assume is some kind of signal for the device, and the bin file which is the generated password, but I can't seem to find reference to which codes the device can receive.

Could you give me hand? or point me to some documentation?

Regards,

Tiago
