Comments on Coding:

In the coding of the program given earlier, for disk Imaging We are proceeding by performing the Following tasks:

• The Structure, geometry is used by getdrivegeometry function using INT 13H Extension, Function Number 0x48. For a Detailed description on INT 13H Extensions, refer the chapter “Handling large hard disks”, Discussed earlier in this book.
