Error Message “Causeway Error” When Running Image for DOS


When attempting to run Image for DOS, a message similar to the following appears:

Causeway Error 09: Unrecoverable Exception. Program Terminated.


This problem can be caused by any of the following conditions:

  • One or more partitions on the system contain file system corruption.
  • The Image for DOS program files are corrupted.
  • You are using Image for DOS on a Lenovo notebook.


Please carry out the following steps to correct this issue:

Resolving a Problem with a Corrupt File System

Run ScanDisk (Windows 9x / Me) or CHKDSK /F (Windows NT / 2000 / XP / 2003 / Vista, Windows 7/8.x/10) on each partition, including the source and target partitions for any image operations you are attempting to carry out. Note: Using chkdsk in Vista or Windows 7/8.x/10 will require that the Command Prompt be run as an administrator.

If the problem remains, recreate your Image for DOS boot media, as explained below.

Replacing a Corrupt Image for DOS Program File

Create a new Image for DOS boot disc or diskette. 

  • If you are using a CD/DVD disc for the Image for DOS boot media, try using a different disc.

  • If you are using a floppy diskette for the Image for DOS boot media, do a complete format on the floppy diskette first to help ensure that the diskette is reliable. Use the FORMAT A: /U command when performing the format of the floppy diskette.
