I. Definition of Partition

A hard disk partition is like a container for storing files. Without a partition, data cannot be saved, and users cannot access the hard disk in Windows File Explorer. In Windows, the disk partition style determines the number of partitions possible – MBR allows up to 4 primary partitions, while GPT allows unlimited primary partitions. Partitions include drive letter, size, and file system information.

2. Method of merging partitions

To merge partitions in Windows 10 using disk management, the merged partitions must be adjacent. For non-adjacent partitions, third-party software like AOMEI Partition Assistant Standard Edition can be used. Here are the steps for merging partitions in Windows 10 disk management.
Step 1: Right-click the (Start) button and select (Disk Management). After entering Disk Management, find the disk partition you want to merge. As shown in the figure below, if you want to merge the D: and E: partitions, right-click the location of the E: partition and select (Delete Volume).

Step 2: A prompt box will pop up, reminding us that deleting this volume will clear all the data on it, please back up all the data you want to keep in advance. If you have backed up the partition data in advance, please click (Yes). The partition will then become “unallocated”.
Step 3: Right-click the previous partition D: and select (Extend Volume) and click (Next Page) on the “Welcome to the Extend Volume Wizard” page.

Step 4: Set the amount of space for expansion, which can be set to the maximum amount of available space. Then click (Next) > (Finish).

Step 5: After that, you can see that the two partitions have been successfully merged, and the D: partition contains the space of the original E: partition.

III. How to recover deleted partition data if no backup was made before merging partitions?

1. Preparations for recovering hard disk partition data

①If you did not back up the partition data before merging partitions, and found that the deleted and merged partition contains important files, you should suspend the use of computer equipment to download files and other operations at this time, so as to avoid new data being stored and overwriting deleted/lost files Data, in the case that no new data is stored and the old data is not damaged due to other reasons, the deleted old data may still be recovered.
②Choose a suitable data recovery software. Some data recovery software cannot recover deleted partition data, so you need to choose a software with partition recovery function, Renee Undeleter has partition recovery function, and supports use on Mac system and Windows system.
