Way 2: How to Recover a Lost Partition in Windows

This method is more complex than Way 1. If you are confident in your technical skills, follow this method using TestDisk, an open-source program designed to recover lost partitions. Follow the steps below to recover a partition in Windows:

Sometimes, the partition may not appear in File Explorer due to a missing drive letter, as Windows fails to assign one. In such cases, the partition isn't lost but lacks a drive letter.

Way 3: Using Disk Management

The initial approach involves leveraging Disk Management, a built-in Windows feature designed for tasks such as deleting, formatting, and altering partition storage. This free and straightforward method allows you to recover the partition.

Steps to Recover the Deleted Partition:

Step 1: Connect your external drive to the computer using a USB cable.

Step 2: Open Control Panel, navigate to System and Security, and under Administrative Tools, click on "Create and format hard disk partitions."

Way 4: Using Diskpart

Diskpart serves as a command interpreter executed via DOS, aiding in the creation of disk partitions, volume management, and partition administration. This method involves utilizing specific commands to modify the drive letter of the external disk. Once the letter is changed, the drive becomes visible in File Explorer.

Steps to Assign Drive Letter Using Diskpart:

Step 1: Open the command prompt by typing "cmd" in the Windows search bar and pressing Enter. In the command line, type "diskpart" and press Enter.

Step 2: Type "list volume" and press Enter to view the volumes of the partitions.
