2. Setup and Installation
This section outlines the general steps for installing your WD Purple surveillance hard drive. Always refer to your surveillance system's or computer's specific manual for detailed installation instructions, as procedures may vary.
2.1. Before You Begin
- Compatibility: Ensure your surveillance system (DVR/NVR) or computer supports 3.5-inch SATA hard drives and has available SATA power and data connectors.
- Safety: Disconnect power from your system before opening the casing. Wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage to components.
- Tools: You will typically need a Phillips head screwdriver. The product includes the hard drive only; mounting hardware or cables are not included.
2.2. Physical Installation Steps
- Open System Casing: Carefully open the casing of your surveillance system or computer.
- Locate Drive Bay: Identify an available 3.5-inch drive bay. Some systems may require a mounting bracket (not included with the hard drive).
- Mount the Drive: Slide the WD Purple hard drive into the drive bay. Secure it with screws on both sides of the drive, if applicable.
- Connect Cables:
- Connect a SATA data cable from the hard drive to an available SATA port on your system's motherboard or DVR/NVR board.
- Connect a SATA power cable from your system's power supply to the hard drive.
- Close Casing: Once connections are secure, close the system casing.

2.3. Initializing and Formatting (Software Setup)
After physical installation, the drive needs to be recognized and prepared by your operating system or surveillance software.
- Power On: Reconnect power and turn on your system.
- System Recognition:
- For DVR/NVR Systems: The system should detect the new drive automatically. Follow on-screen prompts to initialize and format the drive for surveillance recording.
- For PC/Mac: Access Disk Management (Windows) or Disk Utility (macOS). The drive will appear as unallocated space. Initialize the disk (MBR or GPT, typically GPT for drives over 2TB) and then create and format a new volume.
- Configuration: Configure your surveillance software or operating system to use the newly formatted drive for recording.
