To Duplicate a hard disk in Linux first verify the sector size of the hard disk.
lsblk -o NAME,PHY-SeC
Once the sector size is known, this will duplicate disk A to B.
dd if=/dev/sda of=/dev/sdb bs=512 conv=noerror,sync
NOTE: Once the hard disk has been duplicated the server should be shutdown and the second hard disk removed. If the drive is left in place the system will not boot correctly due to duplicate UUID.
