+hddtemp (reads hard disk S.M.A.R.T. info and reports temperature)
+
+hddtemp is a small and daemonizable utility designed to read the
+S.M.A.R.T. information from the given hard disk and report the
+temperature of the disk. Different hard disk manufacturers use
+different raw values in their S.M.A.R.T. data and the hddtemp.db file
+helps to map raw values to actual temperatures.

+
+The hddtemp.db file does not include more recent hard disks as the
+project does not appear to be maintained anymore. To resolve this,
+simply add your disk to the file manually. Run hddtemp on your drive
+to get the expected string and use the other entries in the file as
+templates to create a new one.
+
+Note that only a few hard disks actually differ from the 194C value so
+you can bet your disk will probably use that value too, but I
+recommend using older drives from the same manufacturer that are in the
+file as a guideline.
