Message "Write Error or Disk Full" Displayed While Closing Disc During Imaging

Please note: This article applies to version 1 product(s) only.

This problem can occur when the optical drive does not support the close method being used or the Burn Extra Track option.  Another possibility is a compatibility issue with the media.  To solve this issue:

  • If you are using the Burn Extra Track option (i.e. the IBXT environment variable), try burning a set of discs without using it.
  • Your optical drive may require use of the CD Close Method Z setting, which can be enabled by setting the CDCMZ environment variable before running Image for DOS (e.g. set IFD=CDCMZ). Try burning another set of discs after enabling this option.
  • Ensure you have the devices configured so that there is a master device (but not the source hard drive--preferably the CD/DVD drive itself) on the same channel as the optical drive.
  • Ensure you are using media which is rated at a speed appropriate for your burner.
  • Try a different brand of media (noting that no-name media should generally be avoided).
  • Try burning at a lower speed.
  • Update your optical drive's firmware, if possible.

Also, take note of the numbers provided by Image for DOS in the error message displayed.  Some of the numbers displayed comprise what is known as a "sense code", and may help to diagnose the error.  A sense code is broken down into two main parts: The "additional sense code" (or ASC), and the "additional sense code qualifier" (or ASCQ).

The numbers displayed by Image for DOS 1.96+ in the error dialog will be of the format XX: 11 22 33.  The ASC will be represented by the two-digit group that appears second from the right, and the ASCQ is represented by the rightmost two-digit group.  In this example, the ASC would be 22 (second from the right:  XX: 11 22 33), and the ASCQ would be 33 (rightmost: XX: 11 22 33).

To provide a realistic example, if Image for DOS displayed the error 70: 03 73 03, the ASC would be 73, and the ASCQ would be 03.

Take the ASC and ASCQ shown, and look them up in this sense code listing.  In the case of the example immediately above, where the ASC was 73 and the ASCQ was 03, the table tells us that the underlying error is POWER CALIBRATION AREA ERROR.  If you cannot make sense of the error after looking it up, notify TeraByte Unlimited support for further assistance.
