With O&O DriveLED, however, you now have the ability to recognize a potential malfunction before it happens. You can detect impending crashes while they're on their way. O&O DriveLED gives you the chance to recognize when a crash is coming, and then the opportunity to do something about it. You'll have enough time to backup your data and so avoid losing any of it when exchanging a hard disk. This is time a sudden crash will otherwise never give you. S.M.A.R.T. hardware monitoring.
O&O DriveLED uses the S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) integrated in hard disks to permanently monitor the status of drives. This allows the program to readout the values for essential properties that are detected by the hard disk during a self-diagnosis. Some of these values might be the total number of hours in operation or the read error rate. Over the course of time, the values will deteriorate and are an indication that the hard disk is wearing out. A detailed readout keeps you informed about the most important data on your hard disk: everything from the number of previous system starts up to the current temperature. In this way, O&O DriveLED warns you about impending problems.
