== Structure of the "DSC" file ==
The "DSC" file, if it exists, contains the data from one or more sectors.
If the sector is filled with a single value, then there will not be any data for it in the DSC file. Therefore the DSC file contains the data of sectors which are not filled by a single byte. The data in the DSC file is ordered according to the track and sector ordering given in the HDR file.
