>Description:
        cdrecord fails with a SONY CDU-924S CD-R drive, even in -inq mode.
        the console complains about scsi command 0x25 (read capacity)
        not being supported by the drive.  read capacity seems to work
        okay if a cd-rom is in the drive but not if a blank disk is 
        in the drive (which actually makes sense to me, but I don't 
        know how other drives behave) 

>How-To-Repeat:
        hook up the aforementioned drive on SCSI ID 6, reboot, and do a

        cdrecord dev=/dev/rcd0d:0,6,0 -dummy -inq

        look at the message displayed on the console
        (as well as the stderr output of cdrecord)

>Fix:
        add the following to the quirk table in /sys/dev/scsipi/scsiconf.c:

         "SONY    ", "CD-R   CDU924S  ", "1.1d"}, ADEV_NOCAPACITY},
        {{T_CDROM, T_REMOV,

        (why can't this quirk bit be set automagically if the read capacity
        command fails?)

        (would it be useful to have SCIOSETQUIRK and SCIOGETQUIRK ioctls?
        then the quirks could be maintained in a text file which was
        scanned from /etc/rc*, rather than by compiling them into the kernel)
