Follow these steps to safely install the D25 1TB hard disk in your CCTV DVR or NVR unit.

1. 1
   Power off the DVR/NVR completely — switch off the unit and disconnect the power adapter from the wall socket. Never install a hard disk with the device powered on.
2. 2
   Open the DVR/NVR casing — unscrew the top or side panel using a Phillips screwdriver and place the screws safely aside.
3. 3
   Locate the hard disk bay — find the SATA connector slots and HDD mounting tray or bracket inside the unit.
4. 4
   Mount the hard disk — place the D25 1TB drive into the tray with screw holes aligned and secure it firmly with the mounting screws.
5. 5
   Connect the SATA data cable — plug one end into the hard disk SATA data port and the other into the SATA port on the DVR/NVR mainboard.
6. 6
   Connect the SATA power cable — attach the SATA power connector from the DVR/NVR power supply to the power port on the hard disk.
7. 7
   Close the casing — reattach the panel and tighten all screws securely.
8. 8
   Power on the DVR/NVR — the unit will detect the new hard disk automatically on startup.
9. 9
   Format from DVR/NVR menu — go to Storage Settings → HDD Management → Format. This step is mandatory before recording begins. Formatting will erase all existing data on the drive.
10. 10
    Recording starts automatically — once formatting is complete, the DVR/NVR will begin recording as per your configured schedule and settings.

The D25 1TB hard disk can also be used as secondary storage in a desktop PC. Follow these steps for installation.

1. 1
   Shut down the computer and disconnect power — fully power off and unplug the power cable from the PC case.
2. 2
   Open the PC cabinet — remove the side panel by unscrewing the thumb screws or rear panel screws.
3. 3
   Find an available 3.5 inch drive bay — locate an empty drive bay inside the cabinet suitable for a 3.5 inch SATA hard disk.
4. 4
   Slide in and secure the hard disk — insert the D25 drive into the bay with SATA ports facing inward and secure it with screws on both sides.
5. 5
   Connect the SATA data cable — plug one end into the hard disk and connect the other to an available SATA port on the motherboard.
6. 6
   Connect the SATA power cable — attach a SATA power connector from the PSU to the power port on the hard disk.
7. 7
   Close the cabinet and reconnect power — reattach the side panel, plug in the power cable, and switch on the computer.
8. 8
   Initialise in Windows Disk Management — right-click Start → select Disk Management. The drive appears as unallocated. Right-click → Initialise Disk → choose MBR or GPT → create a New Simple Volume and format as NTFS.
9. 9
   Assign a drive letter — assign a letter (e.g. D: or E:) during volume creation. The drive is now ready to use as additional storage.
