I have found from the partition table that Total n/o sector for the primary partition is 28743 (total sectors). But my ioctl returns total cylinders as 450 i.e. 28800 sectors. As 28743 is NOT any multiple of 64(2*32)i.e sectors*heads, the fdisk tried manipulates it to get multiples of 64. So, finally the best multiple 448 cylinders (i.e. 28672 sector) So, finally that NOT a BUG in the driver instead is a generalization made by fdisk command.
