Basic settings
| The following tabs are found in the configuration dialog. Open the dialog by selecting the symbol marked green in the screen shot (click the image to expand it). The symbol may look different due to the symbol theme you are using.
Opening the configuration dialog.
The settings shown here configure dvdisaster for reading the defective medium. There are no dedicated settings for reconstructing the image from the error correction data.
"Image" tab. First choose the type of error correction data. Pick the setting "ISO/UDF" (marked green) if you have an error correction file. Otherwise choose "ECC/RS02" (marked blue) to process a medium which has been augmented with error correction data. The adaptive reading strategy uses information from the error correction data to make the reading process as efficient as possible. Activate it using the button marked yellow. Leave the remaining settings at the values shown in the screen shot. |
"Image" tab.
"Drive" tab. Leave this tab at the shown default settings for the moment. Some drives might work better using the raw reading mode "21h". See the advanced settings for more information. |
"Drive" tab.
"Reading attempts" tab. The strength of the adaptive reading strategy lies in finding the still readable sectors and avoiding the lengthy process of trying to read defective sectors. Therefore select "raw" reading (marked green) as it will not cost additional processing time, but reduce the number of reading attempts to the minimum values (marked yellow). Use a moderate termination criterium of 128 unreadable sectors (marked blue) for the first reading attempt. Do not activate raw sector caching yet. If it turns out that these settings do not provide enough data for a successful recovery they can be optimized later. |
"Reading attempts" tab.
Not used tabs The "Error correction" tab has no influence on the reading process. The "Misc" tab currently has only functions for creating log files. This is helpful for sending in bug reports but should be left off during normal operation. The "Appearance" tab allows you to adapt the output colors to your taste, but these have no further effects on the reading process.
