Finding a partition as unallocated space that previously contained your important data is pretty alarming; overwriting the partition can worsen the situation if you intend to get back your data. Therefore, you should go for some effective ways to recover unallocated partitions that guarantee data recovery also.
Part 1. Overview of Unallocated Partition
What Is an Unallocated Partition?
As a computer user, you might be fully familiar with the concept of partitions, but an unallocated partition may seem confusing; the unallocated partition is a storage space that doesn't belong to any partition. The term unallocated is self-explanatory; it indicates a space that isn't allocated by data. You can't even store files on such unallocated space unless you perform certain operations to make it usable.
Reasons for Unallocated Partition
If you're encountering an unallocated partition on your system, note that various factors might contribute to making a partition unallocated. In this connection, here we have shed light on a few likely reasons that can cause a partition to become unallocated. Such as:
Formatted or deleted partition
If you accidentally delete or format your partition, it can erase all the data, and the partition becomes unallocated.
The hard drives may become corrupted, given various causes, and such failures make your storage space unallocated.
Malware or Virus attacks
Certain virus or malware attacks can target your system and delete the data or partitions; consequently, the partitions might become unallocated.
Suppose you encounter sudden power failure while writing data to your hard disk or specific partition. This can lead to data loss by showing the partition as unallocated after restarting the system.
