I couldn't resist making a S.M.A.R.T. script using WMIC. It gave me something to do over the holidays.
1) This will only give SMART data for the main drive. (ie: C:\)
2) It will most likely Not give data on Raided or USB drives.
3) It only shows pertinent data columns and ignores all others.
4) It should be good enough for a quick glance and an example how to parse WMIC output.
