I'm sponsoring this case for Gabriel Carrillo.  It's a straight-forward enhancement, so I'm marking it as Self Review.  Please let me know if there is any disagreement and I'll change the case to an actual fast-track.

The case seeks patch binding.

1.0 Description

The cdrw(1) program, by default, assumes a Compact Disc size of 650MB.  If a user inserts a 700MB disc and wishes to write a 680MB image(for example), cdrw(1) will return an error message stating that there is insufficient capacity on the disc.  The solution is to use the -C option, which will cause cdrw to issue SCSI MMC commands that will dynamically determine the disc capacity, rather than falling back on the defaults, resulting in a successful burn.

As 700MB discs have become more common, and image sizes have grown to take advantage of that fact (Solaris 10 8/07 CD image, for example), users find the command syntax increasingly confusing, and don't realize that the write will fail unless -C is specified.  The command-line syntax should remain unmodified for reasons of backwards-compatibility, but cdrw(1) default behavior should be modified such that it always queries the optical drive to determine the capacity of the inserted medium.
