See man smartctl about comand line switches of smartctl (tool of smartmontools). There is an output by --all switch below. See S.M.A.R.T. data description to understanding.
Probably, if you get something not like "SMART overall-health self-assessment test result: PASSED" (see --health switch) you need more attention or a new disk...
