sector

Hi,

I want to develop a program that copies a partition's 'data' only, to another partition. And I want to do it such that the program starts from the first sector of source partition and checks if a sector is used.

If it is used copy it to the destination parition. Else don't copy.

In other words it's like copying only the contents of a partition to another, sector-by-sector.

Question: Is there a way to check if a particular sector on harddisk is used or not?

The programming language I am using is C++ and the underlying filesystem in NTFS.

Thanks a lot.
