Is the physical information( cylinder, Head, sector) reside in HardDisk or BIOS?

From where I get this information?

If there any function in MFC (VC++) to get the physical information?

Physical information is store on the drive itself. The BIOS reads these parameters to determine the type, size and features of the drive.
