Slowly the necessary pieces come into focus: 1) Find the writable-or-not code of sr_mod.ko. 2) Find the writable-or-not code of ide-cd.ko. 3) Move (1) and (2) into cdrom.ko. 4) Teach cdrom.ko to fetch op x46 GPCMD_GET_CONFIGURATION header. 5) Teach cdrom.ko to fetch all reportedly available op x46 data. 6) Learn that more than DVD-RAM is writable. > > 1) Find the writable-or-not code of sr_mod.ko. > > 3) Move (1) and (2) into cdrom.ko. > > 4) Teach cdrom.ko to fetch op x46 GPCMD_GET_CONFIGURATION header. > > 5) Teach cdrom.ko to fetch all reportedly available op x46 data.

CD-RW and DVD+RW support random rewrites if load balanced. Those designs have not pioneered a standard way of saying truly random rewrites supported, other than saying DVD-RAM. Pat LaVarre
