The process of writing to a CD or DVD cannot be interrupted and needs a constant stream of data. Consider using the cdrw –S option to simulate writing to the media to verify that the system can provide data at a sufficient rate for writing to the CD or DVD.

Write errors can be caused by one of the following problems:

• The media cannot handle the drive speed. For example, some media are only certified for 2x or 4x speeds.

• The system is running too many heavy processes that are starving the writing process.

• The image is on a remote system, and network congestion is causing delays in reading the image.

• The source drive is slower than the destination drive.

If any of these problems occur, you can lower the writing speed of the device by using the cdrw –p option.

For example, the following command shows how to simulate writing at 4x speed:

$ cdrw -iS -p 4 image.iso

Media does not support simulated writing
