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. 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.)
