Acronis has a new utility that is completely free and checks your servers or even your desktops hard drives health. You can learn about it and download it here: www.acronis.com/adm
It checks several areas of health and gives you an easy summary. It also can proactively run in the background to keep an eye on things for you.
Of course, if you are on our Worry-Free Network Care plan, we literally run thousands of system checks continuously to insure things are perfect 24 hours a day, seven days a week.
