Check Drive is a disk analyzing tool that scans your hard drive for any errors and tries to fix them. It also works as a disk diagnosis tool, as it shows you the current status of your drive with details such as the amount of garbage you've managed to store so far and whether it needs fragmentation. The program is extremely easy to use: simply select your hard drive letter and let it start scanning. The process doesn't take too long and shows the results on screen right after it finishes. While Check Drive may be a handy tool in case you're constantly getting error messages relating to disk issues, I'm still not sure about its efficiency, mainly because it doesn’t tell you exactly what kind of errors it has found.
