Step-by-Step Guide to Installing and Removing an HDD in a DVR/NVR
1. Safety First
Before starting, unplug your DVR/NVR from the power outlet and disconnect all cables connected to it. This is crucial to avoid the risk of electric shock or accidental damage to the device.
2. Access the Recorder's Interior
Place the DVR/NVR on a stable, flat surface for easy handling. Using a Phillips head screwdriver, remove the screws securing the outer case.
Recorders with a curved top cover will be similar to the sample image below (taken from DVR8-4680X). The screws that hold the cover are underneath and on the sides.

3. Open the Case
After removing the screws, carefully flip the recorder over and lift the lid from the rear.
For Recorders with a curved top cover, be cautious not to pull the lid too far, as cables for the front USB ports and LEDs are often connected inside. Gently set the lid aside while leaving these cables intact.
NOTE: Some recorders have their HDD attached directly to the circuit board (see image 3 below), eliminating the need of cable. Carefully unplug them to the board if you will be replacing them.
4. Identify the Mounting Area
Inside the recorder, locate the mounting points for the hard drive. There are typically eight mounts: four for a standard 3.5” hard drive and four for a smaller 2.5” drive. Choose the appropriate mounts for your hard drive size.

5. Remove or Install the Hard Drive
Remove: Disconnect the two cables (power and data (SATA)) connected to the hard drive. Then, locate the screws that holds the hard drive underneath the recorder. Hold the HDD while unscrewing it to prevent it from falling.
Install: Position the hard drive over the correct mounting points. Hold the drive in place while inserting the screws into the mounting holes and tighten them to secure the drive. Be careful not to over-tighten, as this could damage the hard drive or the mounts—just secure it enough to hold it firmly in place.
Locate the power and data (SATA) cables inside the DVR/NVR. Attach these cables to the corresponding ports on the hard drive. Ensure they are firmly connected but do not use excessive force.
6. Reassemble the Recorder
Place the lid back onto the DVR/NVR, aligning the grooves on the lid with the chassis. Once the lid is correctly positioned, secure it by reinserting and tightening the screws you removed earlier.
DID YOU KNOW? Changing HDD doesn't affect the operating system of your recorder, unlike in PCs. The HDD is only used to store and play recordings; therefore, it is safe to replace the HDD if you need to.
NOTE: Don't forget to format the HDD once you turn on your recorder to store event clips.
