Here is a simple program to extract SN Systems DTL-T14000 DVD Emulator HDD:
MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.
It can only extract files that have not been deleted.
Running it with no arguments prints short usage information.
It takes only one parameter - the input HDD image file name.
Once started, it creates a text file, in which all (non-erased) files from the image are listed (together with some more data) and then asks the user if the program should continue by extracting the files found.
If the initial structures describing the superblocks are missing, it attempts to search for each superblock individually. However this is unreliable and it may even crash the program if there is much damage within a superblock, so using the program on such images is not recommended.
For files that have been deleted or whole deleted supeblocks, it is better to use some tool to search for the particular filetypes, because the links between the structures referencing the files and the files' data are lost in such cases.
The archive also includes a file incompletely describing the HDD structures, should anybody need it, in order to create a more complete program for managing the HDD data for example.
