How to Recover Data after Hard Disk Repartitioning

Slicing a hard drive storage into separate regions is called Disk Partitioning. It’s essentially a logical division of physical hard disk into sections called partitions, which allows better file management and installation of multiple operating system on a single hard drive, etc.

Disk Repartitioning refers to partitioning a hard disk partition again. A user may repartition a hard disk partition or volume to create a new partition and extend or shrink an existing drive volume for reasons such as low space.

While the process is generally safe, if carried out correctly, there are significant chances of error, which can lead to accidental formatting, and permanent data loss.

So if you happen to lose data from an internal or external hard disk while repartitioning, follow this guide to safely recover your files from a formatted or corrupt partition.
