If you need to repartition your hard drives without risking losing huge quantity of data, you can use Easeus Partition Manager. The tool is free to download and use and also comes with a comprehensive user manual. The user interface is a bit intimidating for the novice user, so the user manual is really a great plus. With this utility, once you get the hang of its options and features, you can easily resize, format, copy or move partitions in minutes. It also works with external drives, flash drives and even RAID drives.
You can use the program to convert drives to local, change their labels and even defragment them. The utility enables you to explore partitions and check them for consistency. It also comes with some powerful features for migrating data from your old hard drive to new, fast SSD drives. Cloning partitions is also a breeze using the built-in wizards. The only cons are the pop-up ads that display from time to time. However, since the program is free, we agree that the software developers have to make a living somehow.
