Hey guys, i just installed HD Tune to check health of my HDD. This HDD was bought 8 years ago and I never had any problems with it. When I checked "Health" tab it showed me "status failed" on Airflow temperature and that I need to replace my HDD, but it shows that airflow temperature is 18 degrees celsius, and I don't think this is high, or I don't understand something!? Should I be worried about this since I have about 100 GB precious data on this drive on second partition?
