I have two identical HD in a box and want to duplicate sda to sdb
I want sdb to be bootable just in case something happens to sda so I can swap the drives and boot.
Do I boot from USB and run:
dd if=/dev/sda of=/dev/sdb bs=512 count=1
fdisk -l /dev/sda
Disk /dev/sda: 596.2 GiB, 640135028736 bytes, 1250263728 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x000f2548
Device Boot Start End Blocks Id System
/dev/sda1 * 63 80324 40131 83 Linux
/dev/sda2 80325 16868249 8393962+ 82 Linux swap / Solaris
/dev/sda3 16868250 121740569 52436160 83 Linux
/dev/sda4 121740570 1250258624 564259027+ 83 Linux
fdisk -l /dev/sdb
Disk /dev/sdb: 596.2 GiB, 640133946880 bytes, 1250261615 sectors
