Copy Data stored on MBR

I'm using Redhat Linux 9.0.

How to copy data that's stored on the MBR using dd command?

What is the maximum size of MBR?

Thanks,

MBR resides on the first sector of the first partition of the primary HD.

Is it right?

Thanks,

No, the MBR is the very first sector on a hard disk, while a partition never begins at this first sector.

dd if=/dev/hda of=hda_mbr.sav bs=512 count=1

copies the MBR of the primary hard disk to the file hda_mbr.sav.
