I'm developing an application that can get detailed informations from an optical device via low level MMC and SPC commands. (and makes some other things)
I have only one problem when it comes to retrive the HD DVD-R/RW DL related informations. Even though the two types (HD DVD-R DL and HD DVD-RW DL) are defined in the latest MMC6 official documentation more exactly in the profiles list. I can't get if an optical device can write those medias. If those types are returned in the profiles list with the GET CONFIGURATION COMMAND that means only that the drive can read, or maybe write such medias, but to check if the drive can write those types you must to get the features and see if there is an appropriate feature for HD DVD-R DL and HD DVD-RW DL. But in MMC6 there is no such feature. There are only three HD DVD related features: HD DVD Read, HD DVD Write and HD DVD-RW Fragment Recording. With the mode sense, mode page 0x2A command you can't get that information either because it is not defined in the returned structure (in SPC3 documentation). The best thing you can do is to see if the device reads those medias (via the profile list), but how to check if a drive writes such medias ?
