Note: SATA data cables, power cables, and mounting screws are usually supplied with your NVR/DVR system or computer chassis and are not included with the hard drive.

4. Setup

4.1 Physical Installation

1. Prepare Your System: Power off your Network Video Recorder (NVR), Digital Video Recorder (DVR), or computer and disconnect the power cord.
2. Open Chassis: Open the chassis of your NVR/DVR or computer to access the drive bays.
3. Mount the Drive: Carefully slide the WD Purple hard drive into an available 3.5-inch drive bay. Secure it with appropriate mounting screws.
4. Connect Cables:
   • Connect a SATA data cable from the hard drive to an available SATA port on your system's motherboard or NVR/DVR board.
   • Connect a SATA power cable from your system's power supply to the hard drive.
5. Close Chassis: Once connections are secure, close the chassis and reconnect the power cord.

4.2 Initializing and Formatting

After physical installation, your system may require the drive to be initialized and formatted. The process varies depending on your NVR/DVR system or operating system (Windows/macOS).

• NVR/DVR Systems: Most surveillance systems will automatically detect a new drive and prompt you to format it. Follow the on-screen instructions provided by your NVR/DVR software.
• Computer Systems (for testing or specific applications):
  • Windows: Go to Disk Management (right-click Start button > Disk Management). Locate the unallocated drive, initialize it (GPT recommended for 4TB drives), and then create and format a new simple volume.
  • macOS: Use Disk Utility (Applications > Utilities > Disk Utility). Select the drive, erase it, and choose a suitable format (e.g., APFS, Mac OS Extended).

5. Operating Principles

The WD Purple drive is optimized for the unique demands of surveillance workloads:

• 24/7 Continuous Operation: Designed for always-on recording environments, ensuring reliable performance around the clock.
• AllFrame Technology: This exclusive technology works with ATA streaming to reduce frame loss, improve playback, and support more camera bays within a surveillance system.
• High Workload Rating: Engineered to handle the high write-intensive workloads typical of surveillance systems, supporting up to 64 HD cameras simultaneously.
• Low Power Consumption: Optimized for lower power consumption and reduced heat generation, contributing to long-term reliability in demanding environments.

Once installed and formatted, the drive will function as the primary storage for your surveillance footage, managed by your NVR/DVR system.

6. Maintenance

While WD Purple drives are built for durability, proper maintenance practices can extend their lifespan and ensure data integrity:

• System Ventilation: Ensure your NVR/DVR or computer chassis has adequate airflow to prevent the drive from overheating. High temperatures can degrade performance and lifespan.
• Firmware Updates: Periodically check the Western Digital support website for any available firmware updates for your drive model. Follow instructions carefully if an update is recommended.
• Data Backup: Although surveillance footage is often overwritten, consider backing up critical footage to external storage if required for long-term retention or evidence.
• Physical Cleanliness: Keep the area around your surveillance system clean and free of dust, which can impede ventilation.

7. Troubleshooting

If you encounter issues with your WD Purple hard drive, consider the following steps:

• Drive Not Detected:
  • Verify that both the SATA data cable and power cable are securely connected to the drive and the system.
  • Try a different SATA port or cable.
  • Ensure the system's BIOS/UEFI or NVR/DVR settings are configured to detect SATA drives.
• System Freezes or Crashes:
  • Check for overheating. Ensure proper ventilation.
  • Run diagnostic tools provided by your NVR/DVR system or Western Digital (if applicable for your setup) to check drive health.
• Poor Video Recording Performance (Frame Drops, Pixelation):
  • Ensure the drive is properly formatted for your surveillance system.
  • Verify that the number of cameras and their resolution do not exceed the system's or drive's recommended capacity.
  • Check for any system-level bottlenecks (e.g., network speed, CPU usage of the NVR/DVR).
• Unusual Noises:
  • A clicking or grinding noise can indicate a drive failure. Immediately back up any critical data if possible and consider replacing the drive.

If issues persist, consult your NVR/DVR system's manual or contact Western Digital support.
