As far as I can tell, this app only pretty-prints a subset of the S.M.A.R.T. values. For S.M.A.R.T. to work, it needs to be pointed to the individual physical disks, not the logical disks (in addition to being enabled in the BIOS setup, and the drives actually supporting S.M.A.R.T.) To get the actual data, you can either boot a Linux liveCD (pretty much any one will do) and run "smartctl -a /dev/sda" (and sdb, sdc, sdd), or install cygwin and the "smartmontools" package (under "utils"), and do the same. If so, note that the S.M.A.R.T. counters count down from a set value towards an alert value, not up. So if the Power_On_Hours report 94 with a raw value of 3000, it means that for this drive, 3000 hours is considered equal to 100-94 = 6% of how long the drive can be powered on before it's expected to fail. Of course, that doesn't mean the drive will last that long -- it's just one of many parameters.
