Applies to: Hanwha Vision NVRs (PRN, XRN, QRN, ARN series) and DVRs (HRX and ARD series)

Issue Summary

A hard disk drive (HDD) that is incompatible with the NVR or DVR may cause errors after installation or replacement. Although an HDD may be detected and show a Normal status, it may not be listed as compatible for the recorder. Detection alone does not confirm compatibility. This article explains how to verify HDD compatibility and replace an unsupported HDD.

Resolution

To verify the HDD compatibility:

1. Determine whether the issue began after HDD installation or replacement. If the previous HDD worked normally, check the replacement HDD.
    
2. Locate the complete NVR model number on the product label or System Information page.
    
3. Record the manufacturer, capacity, complete model number, and suffix from the HDD label.
    
4. Open the Hanwha Vision HDD Compatibility page.
    
5. Select the exact Recorder Model Name, then compare the HDD model number, Brand, and Storage fields with the HDD label. 
   
   For RAID systems, verify the RAID field.
    
6. If the HDD is listed, contact Hanwha Vision Technical Support with the NVR model, firmware version, HDD manufacturer, complete model number, capacity, and exact error message.
    
7. If the HDD is not listed, back up required recordings, then shut down the Recorder and disconnect power.
    
8. Install a supported HDD according to the product guide.
    
9.  Navigate to Settings > Device > Storage Media.
    
10. Verify that the HDD is listed and the capacity is correct.
     
11. If an initialization or format prompt appears, follow the on-screen instructions.
     

12. Verify that the status changes to Normal. 

    IMPORTANT: Initializing or formatting the HDD erases all data on the selected 
    HDD.

13. Create a test recording, then locate and play it to verify normal operation.
     
14. Verify that the HDD error, warning, or buzzer does not return.
     
15. If the error persists or returns, contact Hanwha Vision Technical Support with the recorder model, firmware version, HDD manufacturer, complete model number, capacity, exact error message, and recording and playback test results.
