Method 1: Plug-and-Play Setup (Quick Use)

Most modern drives are pre-formatted and ready to use immediately.

Steps:

  1. Connect the external hard drive via USB port (USB-A or USB-C).

  3. Open File Explorer (Windows + E).

  4. Under This PC, check for a new drive letter (e.g., D: or E:).

  5. Start dragging and dropping files onto the drive.

👉 If the drive shows up, you’re good to go. If not, move on to formatting steps.

If your drive doesn’t appear in File Explorer, it might need initialization.

Steps:

    • MBR (for older systems).

  5. Right-click the unallocated space → Select New Simple Volume.

  6. Follow the wizard:
