Way 2. Format an External Hard Drive via File Explorer

Formatting an external hard drive via File Explorer is a straightforward and accessible method for users. Utilizing the native capabilities of your operating system, this approach allows you to quickly format your external drive without needing any third-party software. Here's how you can do it:

Step 1: Check if your drive is correctly connected to your computer. Now access File Explorer on your Windows computer by pressing the "Windows + E" key. You should see your connected external hard drive listed under "This PC" or "Computer" in the left-hand navigation pane.

Step 2: Right-click the icon representing your external hard drive and choose "Format" from the context menu. A formatting window will appear now, where you can choose the file system (e.g., NTFS, exFAT, or FAT32) and allocation unit size.

Step 3: You'll have the option to perform whether in a quick format or a full format. After making a choice, double-check your selections. Afterward, when you are ready to proceed, click "Start" to initiate the formatting process.

Step 4: A warning message will appear, informing you that all data on the external hard drive will be deleted. Confirm this action to begin the format. The formatting process will commence and will take some time to finish.

Way 3. Format an External Hard Drive via Disk Management

Another way to format an external hard drive is via Disk Management. It provides a native and efficient method for Windows users to format their storage devices. Disk Management is a built-in utility allowing you to manage disks and partitions, providing more advanced options than the File Explorer method. Here's how to format your external hard drive using Disk Management:

Step 1: After connecting your external hard disk, press the Windows key + X on your keyboard and select "Disk Management" from the menu that appears. In Disk Management, you can see a list of all connected storage devices. Navigate your external hard drive in the list; it will be labeled with the drive letter and its capacity.

Step 2: Right-click on the partition representing your external hard drive, and from the context menu, select "Format." In the Format dialog box, specify the file system (e.g., NTFS, exFAT, or FAT32) and allocation unit size. By default, Disk Management performs a quick format, which is faster but less thorough.

Step 3: Uncheck the "Perform a quick format" option to ensure a complete data wipe. Now click "OK" to start formatting and agree to a warning to format your external hard drive.

Way 4. Format an External Hard Drive via Command Prompt

You can also format the external hard drive via Command Prompt. It provides advanced users with a powerful and flexible method to format their storage devices. Command Prompt allows more precise control over the format process and offers additional parameters unavailable through other methods.

However, be cautious when using Command Prompt, as incorrect commands can lead to data loss. Follow these steps carefully:

Step 1: Press the Windows key and type Command Prompt in the search bar after connecting the external hard drive to your PC. Now right-click "Command Prompt" in the results, and select "Run as administrator."

Step 2: Type the diskpart command in the Command Prompt window and press Enter. Now run the command list disk to view a list of all connected disks on your computer. Afterward, choose the targeted disk using the select disk X command. Here "X" is the disk number of your external hard drive.

Step 3: Use the command clean to wipe all partitions and data on the external hard drive. Later, use the command create partition primary to create a new primary partition on the disk. Next, type format fs=NTFS quick to format the newly created partition with the NTFS file system.

Step 4: If the partition is not automatically assigned a drive letter, use the command assign to assign a letter (such as E:). Lastly, type exit and press Enter to leave the DiskPart utility.

Phase 3. Recover the Data from the Backup

After successfully formatting your external hard drive without losing data using one of the four methods discussed earlier, the final phase is to recover the data from the backup you created.
