I'll add this also. There are two kinds of this: Some drives lie about their personality. This happened to me with my Really Ancient SONY MOD drive (actually an ESDI drive, with a separate ESDI-to-SCSI bridge), and caused me to modify scsiconf.c. The CD-R is a superset of the CDROM. Since CD-R's aren't fully covered by the SCSI-2 spec, the vendors seem to be undecided of whether to call their baby T_READONLY or T_WRITEONCE. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
