The problem seems to be lack of implementation. Recently a project has emerged that implements the OPAL SSC (self-encrpyting drive) functionality that's missing in hdparm.
MSED (for "Manage Self Encrypting Drives") lives here: https://github.com/r0m30/msed The fix for hdparm, one presumes, is to make the hdparm password submission feature dependant on msed. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
