Program: Diskread.pas
File exe: Diskread.exe

Don't be frightened when the red control of the disk mechanism lightsup immediately after the program is running. This only means that the program reads the disk physically. What is the use of it? Since DOS 3.0, each disk includes a sector which the system does not use in order to maintain the compatibility. You must understand that the majority of the installation programs record the information to this sector, thus producing the floppy disk which can't be copied. You may use it either as a hacker program or as a part of your own installation disks.
