S.M.A.R.T. self tests for an immediate check of your hard disks Immediately after installation O&O DriveLED provides you the ability to make an intensive analysis of all of your hard disks. Every hard disk that supports S.M.A.R.T. is able to run self tests. Using O&O DriveLED you can start a self test of your hard disk with only one mouse click. During the tests several parameters and functions are being consecutively checked. Among other things, the interface, the surface and the mechanics - actually every read head - are being checked. Afterwards the error log will be read and finally also the S.M.A.R.T. system itself will be tested. At the end and if there were no failures found, the corresponding entry lights up in green color. If some failures occurred, O&O DriveLED will notify you. In this case it is recommended to backup your data. Access monitoring on the desktop Have you often asked yourself why your hard disk starts up even when you aren't writing anything to it? Until now, you could only check hard disk activity by looking at the little lamp (LED) on the front of your computer. But who wants to be constantly looking under the table whilst trying to work or play games? From now on, you don't have to crane your neck anymore to see if your hard disk is currently active. Now you can use O&O DriveLED. O&O DriveLED takes the hard disk LED, which is built into your computer, and puts it right there on your monitor screen. And there's more - you can see information about activity on virtual drives, e.g. network drives, and you can easily tell the difference between disk reading and disk writing activity.
