How do skip MBR & partition table while doing dd of a partition

I need to copy a SATA partition to external usb partition , both partitions are same in size but total disk size are different , i want to copy only the data and not concerned about boot sector and so don't want copy the SATA partition info in to USB disk. So in dd command , is skipping 1 block ( skip=1) is enough?. Thanks
