Wiping a hard drive on Windows 10 using the Command Prompt ensures that all data is permanently erased. This method is highly effective and simple, involving a series of steps anyone can follow. First, open Command Prompt with administrative privileges, then use a series of commands to locate and fully clean the drive.
How to Wipe a Hard Drive on Windows 10 Command Prompt
Using Command Prompt to wipe a hard drive involves running specific commands that will identify and erase all data on the selected drive. Follow these steps carefully to ensure you clean the right drive.
Step 1: Open Command Prompt as Administrator
First, open the Start menu, type “cmd,” right-click Command Prompt, and select “Run as administrator.”
Running as an administrator gives you the necessary permissions to execute commands that can affect the entire system. If you skip this step, you might encounter permission errors.
Step 2: Launch Diskpart
Next, type diskpart into Command Prompt and press Enter.
Diskpart is a powerful tool that allows you to manage your computer’s drives. Opening Diskpart ensures you can perform advanced tasks like wiping a hard drive.
Step 3: List Disks
Type list disk and press Enter to display all the disks connected to your computer.
This command shows a list of all available disks, helping you identify which one you want to wipe. Make sure to note the disk number of the target drive.
Step 4: Select Disk
Type select disk X (replace X with the number of the disk you want to wipe) and press Enter.
Selecting the correct disk is crucial. Double-check the disk number to avoid wiping the wrong drive, as this action is irreversible.
Step 5: Clean the Disk
Finally, type clean and press Enter to wipe the selected disk.
The ‘clean’ command removes all partitions and data on the disk, making it appear as unallocated space. This process may take a few minutes, depending on the size of the disk.
After completing these steps, your hard drive will be entirely wiped, and all data will be erased. The disk will be ready for new partitions and formatting, just like a brand-new drive.
