Clone disk/partition to external HDD/SSD with ‘dd’ command in Linux

To clone HDD/partition with dd command, the destination HDD/partition must be equal or larger in size than the source.

sudo dd if=/dev/sda5 of=/dev/sdb2 conv=sync,noerror bs=64K status=progress

if=/dev/sda5/path/to/the/source/disk

if=/dev/sda5/path/to/the/destination/disk

conv=sync,noerror // skip errors not abort command

bs = 64K // block size 64K is OK

status=progress // display status
