O&O DriveLED 4 Pro

An early-warning system for hard disk crashes

When is it the right time for giving your computer a rest? - When it’s too hot? - Overloaded? - Vital components are on the verge of breaking down? No other single part of the modern computer system is more susceptible to malfunction than the hard disk.
 
In fact, such a malfunction can come without warning and often strikes while the computer’s being used. O&O DriveLED, working quietly in the background, permanently monitors the status of your hard disks and warns you of any impending problems.
 
With it, you’ll always have time to backup your data and so avoid losing any of it when exchanging a hard disk. This is time a sudden crash will never give you.
