Wondering how long your hard drive has to live? This utility will help you make the most of your time together, so you can prepare for life without it once it's gone. From its vantage point in your system tray, HDD Health 3.3 uses Self Monitoring and Reporting Technology (S.M.A.R.T.), which is built into all new hard disks to assess your hard drive's condition and send you alerts when it's time to put your hard drive's affairs in order. Neither these alerts nor the records the program logs for you will tax your system resources.
