Yes, /dev/gpt/disk06-live == ada0. If you have the possibility to run a scrub of the pool, there should be no additional checksum errors accouring *after* the scrub is *finished*. If checksum errors still appear on this disk after the scrub is finished, you should have a look at the hardware (cable/disk) and take appropriate replacement actions.
