Disc File Rescuer
by Matthew Astley

This program allows files to be rescued from discs which give a "Bad Sector" error. When the application is run you will be asked for the full pathname of the defective file, and the full pathname of the file to which all the rescued data will be copied, and then the program will do its best. It is a good idea to put the destination file on a different disc to the defective file, for example on a RAM disc, because if the defective disc has corrupted one file, it could corrupt again.

The program works by reading the defective file 1K at a time, and if a particular read fails, then it simply writes question marks to the destination file. Thus, when you load in the rescued data, some data will be lost. This technique is particularly useful for text files, and files used by word processors and even DTP packages. However, it is unlikely to work with archived or compressed files.
