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:

    o  1X

    o  2X

    o  4X

    o  8X

    o  16X

    o  32X

    o  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 performan
       constraints exist.

    CD drives can select speeds faster than those supported by the
    particular media loaded in the drive. HP 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.)
