HD Checker is a program to monitor the right functionality of your hard disk(s).It is based of S.M.A.R.T. technology to control the status of your EIDE hard disk(s), to prevent data loss and predict failures.If HD Checker detects a change in the hard disk status can notify this event in different ways using popup windows and/or by email (useful to control remote computers).HD Checker monitors all the attributes available for the hard disk and you can choose when it has to alert you by selecting a customable percentage threshold in which every hard disk attribute can change with no alert.
