SIGuardian is the only tool that allows you to fully control the health of your HDD's and prevents data loss because of failures. Using S.M.A.R.T. - technology included in all modern HDD's - SIGuardian predicts the end date of HDD lifetime, so you can make a backup copy of all your data. Only SIGuardian can show all of the information about S.M.A.R.T. - attribute values, worst and threshold values, and more!
