I'm afraid things are not as simple as that. Unfortunately you cannot expect ATAPI drives to properly reject MODE_{SENSE,SELECT}_6 and try the _10 variants in that case: the reason why ATAPICAM inconditionnally translates the _6 commands into _10 is because some ATAPI drives have been found to lock up when they rececive the _6 commands, whereas the ATAPI specification only mandates the implementation of the _10 versions. > - The media validation routine also reads the table of contents off > the drive. Great! That could also allow the creation of per-track /dev nodes, as acd has.
