Many software programs detect errors. Data recovery programs can be more prone to errors because they are dealing with hardware and file structures that are often corrupted, or in an unknown state. Therefore it is not impossible that the program may hang or crash. The following will give some guidance of how to handle such situations.
To help with 'remote' problem finding the program stores short trace files. A new one is started everytime that CnW starts and has the name trace?.txt where ? is a number of 1 - 9. The files are created, and re-used in sequence so often the releavnt file will be the one with the most recent date. However, if the problem occurred a few runs before, then the trace for this run will still be available. Sending this file to CnW will assist in resolving any problems.
