Qualifiers

 

/BELL
   Sounds an audible signal when the requested recording operation
   completes successfully.
 

/FORMAT
      /FORMAT[=keyword]
      /NOFORMAT (default)

   Requests that rewritable (RW) media be formatted or reformatted
   prior to use. This qualifier is required for writing to blank
   rewritable media or rewriting rewritable media.

   If the target media cannot be formatted, this command qualifier
   is ignored.

   If not specified, the appropriate keyword is automatically
   selected for the fastest formatting speed available for the
   target recording media.

   Keywords for the /FORMAT Qualifier lists available keywords.

   Keyword  Function, Comments

   WAIT     Applies to DVD+RW. The default for the /FORMAT qualifier
            is not to wait for the formatting to complete because
            waiting is usually unnecessary and far slower.

            Selecting WAIT causes the entire format to run
            synchronously to completion before beginning the
            recording operation.

            The default is to:

            o  Operate asynchronously

            o  Perform background formatting

            o  Run both the media format operation and the recording
               operations concurrently

   ERASE    Applies to CD-RW.

            The default for the /FORMAT qualifier is to perform a
            quick erasure because a full erasure is usually both
            unnecessary and far slower.

            Selecting ERASE causes the CD-RW rewritable disk to
            be entirely erased as part of the format operation.
            This erasure is performed and is completed before the
            recording operation begins.

            The default is to perform a quick erasure.
 

/LOG
      /LOG (default)
      /NOLOG

   Shows basic device information and the progress of the recording
   operation. Use /NOLOG to disable the normal output from the
   utility.
 

/SPEED
   If you must use the lower-speed or poor-quality CD recording
   media, the /SPEED qualifier is often required for successful
   completion of the recording process. You might need to select
   a recording speed below the rated speed of the CD drive itself.
   Specifically, you might need to select a recording speed that
   is compatible with both the CD drive and the CD recording media
   loaded in the drive.

   The /SPEED qualifier accepts a single keyword for a requested
   device speed:

      1X
      2X
      4X
      8X
      16X
      32X
      MAXIMUM

   The CDDVD utility attempts to match the requested speed to a
   speed that the device supports. (Not all devices support all
   speeds, including the lowest speed, 1X, or the highest speed
   available.) The default speed is the maximum speed that the
   target device supports. DVD+R/RW drives select the maximum
   recording speed based on information encoded on the media.

   You need to specify this qualifier only under one of the
   following circumstances:

   o  When incompatibilities or recording errors are reported during
      a previous failed recording operation.

   o  If the CD media in use has a rated recording speed below the
      drive default recording settings.

   o  If CDDVD application, processor, or system I/O performance
      constraints exist.

   CD drives can select speeds faster than those supported by the
   particular media loaded in the drive. VSI recommends that you
   select only media that match the recording capabilities of the
   drive. In other words, do not attempt to exceed the recording
   speed limits of the particular CD media. Selecting faster media
   will not make a slow drive record any faster, and selecting
   faster speeds with slow media can trigger recording errors and
   corrupt media.

   If the recording process fails during the recording operation,
   discard the write-once media and try a slower recording speed.
   (Note that you can attempt to reformat and rerecord on rewritable
   media.)
 

/VERIFY
   Specifies that the contents of the output media be compared to
   the contents of the input source after the recording operation.
   Any data comparison errors detected are displayed.
 

/WRITE
      /WRITE (default)
      /NOWRITE

   Allows you to test the system and device I/O throughput and the
   command syntax without recording on the target media.

   If you specify /NOWRITE and if the target drive supports the
   underlying test-write hardware capability, all I/O operates as
   usual although /NOWRITE disables writing to the media.

   /WRITE is the default, and causes the target optical media to be
   written.
