Medium and Image filesystem

dvdisaster provides several ways of determining the image size when reading media:

ECC/RS02: dvdisaster will use the image size recorded in the RS02 error correction information. This option must be selected for reading augmented images; otherwise the resulting image may be incomplete.
It is possible to read images containing no RS02 error correction information with this option set. In this case the image size will be determined as in the "ISO/UDF" setting. However searching for the error correction information may delay the start of the reading operation.

ISO/UDF: dvdisaster will determine the image size from the ISO/UDF file system.
Caution: This is only suitable for working with error correction files as it results in incomplete images if used for reading images augmented with RS02 error correction information.

Drive: The image size reported by the drive will be used. Since this information is typically wrong for DVD-RW/+RW/-RAM media this option is only present for backwards compatibility with older dvdisaster versions.

Setting for local files

Automatic file name extension(1): When this switch is set, files will be automatically appended with ".iso" or ".ecc" suffixes if no other file name extension is already present.

Split file into segments (2): Allows working with file systems which are limited to 2GB per file (e.g. FAT from Windows). Created files are spread over upto 100 segments called "medium00.iso", "medium01.iso" etc. at the cost of a small performance hit.

Automatic file creation and deletion

Create error correction file (1): Automatically creates an error correction file after reading in an image. Together with the "Remove image" option this will speed up error correction file generation for a series of different media.

Remove image (2): If this switch is set, the image file will be deleted following the successful generation of the respective error correction file.
