Just like any other type of file, partitions can get lost due a variety of reasons and partition deletion occurs frequently. However, sometimes a partition may disappear, leaving unallocated disk space. Partitions can be created during Windows installation or by disk management and third-party partition manager software. Once a system crash occurs, your data won't get affected. Windows treats each partition as an independent drive, so you can separate OS and personal data on different partitions, for example, you can create two or more partitions on hard drive, one for Windows and the others for photos, videos, or documents.
