//version 0.1.0
/* Using Structure to hold data+Floppy disk stats
Original code :A Piece of COde that extracts floppy disk geometry information,
its been writen in pure C and has been tested and ran seccessfully under TC 3 ...
Added session:Floppy Disk Stat reader!, it is intended to show the floppy
-disk information rather than its FAT info or floppy geometry!
