Finding hard disk sector

["Vaibhav Nipunage" <linuxsyspro@xxxxxxxxx>]

Hello Friends,

I want to find first sector of the hard disk partation using C. Means detail information of that hard disk ie what is start sector and end sector of the partation. So that after finding that sector I can read/write on that sector. 

Please help me.

Thanks in advance.
