Every time when it comes to data recovery, recovering deleted or lost partition is always under the spotlight. People may delete their partition by mistake and want to make up. That's why you need this article, which introduces all the effective methods to recover deleted or lost partition in detail.

Generally, a partition is a logical separation from the whole drive that enables users to better manage their hard disks. In Windows, partitions are usually created when installing operating systems or in Disk Management. Unfortunately, sometimes the partition you created does not show up and becomes inaccessible. When your system highlights extra-unallocated space beside the original partition, it means the partition is deleted or lost. In that case, the files stored in that partition are likely to get lost.

That's when you need to recover deleted partition in Windows 10/11 as soon as possible.
