I have a technical question about Plextor's FUA command. I did not find any informations (i.e. CDB) about it on the web. Can someone give me the technical description? SCSI CDB would be enough. I want to test something with own code, and I really need that information. thanks!!!!!

It would also be interesting, how to detect support for that command. I guess, I just send it to the drive and look if request sense gives me "ok".

Background: I experiment with Read CDDA (D8h) and that FUA-flag there doesn't work with my Plextors ("illegal flag in CDB").
