use dd to clone drive

//ubuntu terminal

//list disk

sudo lsblk

//clone disk

sudo dd if = /dev/sda of = /dev/sdb

“if” represents inputfile, and “of” represents output file. So the exact copy of /dev/sda will be available in /dev/sdb.

//watch dd progress

//open another terminal

sudo watch -n5 'sudo kill -USR1 $(pgrep ^dd)'
