CheckDrive is a free, efficient and user-friendly software for checking hard disk errors and instantly correcting them on Windows XP, Vista, 7, and 8.

The software also identifies the current fragmentation status of your hard drives and the amount of garbage on your disks. With the latest version, CheckDrive shows the S.M.A.R.T. data and calculates a health status from it. Additionally, the Background Guard immediately notifies you of errors as soon as they occur.
Since the release of version 2012, users can visualize the usage of their hard drives with the FolderVisualizer module. It analyzes your disk drives and displays which files and folders occupy most of your disk space. The FolderVisualizer can also produce lists of the top-100 space-using files, as well as statistics and charts about various file types on your drive.
From version 2013 onwards, CheckDrive provides more detailed information about the hard drive, including the manufacturer logo. The latest version (2014) of CheckDrive comes with a new feature called Automatic Verification. Users can request CheckDrive to automatically check their hard drive(s). The integrated task scheduler allows you to set the check interval and activate the task simultaneously with just one click.
In conclusion, CheckDrive is a powerful software that provides an easy way to check for hard drive errors, detect current fragmentation status, and assess a hard drive's health. The FolderVisualizer module provides a detailed analysis of your disk drives and allows you to manage your disk space wisely. The Automatic Verification feature in the latest version of CheckDrive makes it even more convenient for users to ensure that their hard drives are in good condition.
