About Partition

Although you do not need to understand how partitions work to recover partitions, at least you have a very basic understanding of the role of partitions in allowing you to store data on storage devices, which can help you choose the best possible recovery method and avoid making potentially catastrophic mistakes.

Partition definition: the part of a storage device that is separate from other segments. You can think of a partition as a container for data stored on a storage device, such as an internal hard drive or USB flash drive. Without at least one partition, Windows will not know where to save files, which will make the storage device almost useless. The partition information is stored in the partition table, which is located in a special area on the storage device, called the master boot record (MBR) or GUID partition table (GPT) or other similar area. The information stored in the partition table includes the file system of each partition on the storage device. This information is very important because different operating systems can only access the partitions of a specific file system: when a partition does not have any file system, it will be displayed as RAW, and like an unpartitioned storage device, it cannot be used to save files.

Can the deleted partition be restored?

To determine whether a lost partition on Windows 10 can be recovered, you must first find out what happened to it, and the disk management can help you do that.

The purpose of this utility is to enable advanced storage tasks that cannot be performed from file explorer, which lists only partitions that are in good working condition. To start the disk management, simply open the Start menu, enter Disk Management, and press Enter.

You should see all the storage devices connected to the computer and their partitions. The Disk Management tool displays any physical space that does not belong to partitions as Unallocated. The partition with no file system is displayed as RAW. You might also encounter a partition that looks healthy but is not assigned a drive letter. In all of these cases, partition recovery is usually possible.

On the other hand, when the lost partition has been clearly overwritten by another partition and used to store new data, partition recovery is usually impossible. In this case, the only option is to scan the entire storage device using a data recovery software application.

The slightest adjustment can result in the loss or deletion of important disk volumes. Therefore, clarity is recommended when it comes to making changes to the disk management system in Windows 10.
