How to Fix the 'Recording Failed' Error on Your Zosi Security System
The "Recording Failed" error on a Zosi DVR or NVR is a critical alert that needs immediate attention. It means your security system is unable to save footage, leaving your property unmonitored. This issue typically points to a problem with data storage but can also be caused by power or software glitches.
This guide will help you systematically troubleshoot the "Recording Failed" error, identify the underlying cause, and get your system back to recording reliably.
## Understanding the 'Recording Failed' Notification
Unlike simply noticing gaps in your timeline, this error is an active notification from your system. It's telling you that it has attempted to write video data to the hard drive but was unsuccessful. The common symptoms associated with this error include:
- A pop-up error message on the monitor stating "Recording Failed."
- A continuous beeping sound from the DVR/NVR unit.
- The hard drive (HDD) status shows as "Error" or is not visible in the system menu.
- No new video clips are being saved, and playback for recent events is unavailable.
- The recording icon, usually a small red dot, is missing from the camera feeds.
## Step-by-Step Troubleshooting Guide
Let's work through the potential solutions, starting with the most likely culprits.
### 1. Check the Hard Disk Drive (HDD) Status
The overwhelming majority of "Recording Failed" errors are directly related to the hard drive.
- Navigate to the HDD Menu: Log into your Zosi system using a connected mouse and monitor. Go to the main menu and find a section named "HDD Management," "Storage," or "Disk Info."
- Analyse the Status: The system will show you the installed hard drive. Look at its status.
- Normal: If the status is "Normal," the issue might be software-related.
- Error / Unformatted / Not Found: Any of these statuses indicate a direct problem with the drive.
- Reformat the HDD: The first step to fixing a drive error is to reformat it. There will be a "Format" button in this menu. Important: Formatting will erase all previously recorded footage. If the format completes successfully, the error may be resolved.
- Listen to the Drive: Power down the system, open the case, and power it back on. Listen to the hard drive. You should hear it spin up and make quiet clicking sounds as it operates. If you hear loud clicking, grinding, or no sound at all, the drive has likely failed physically.
### 2. Verify the Power Supply
The hard drive needs sufficient and stable power to function. An incorrect or failing power adapter is a common cause of HDD-related errors.
- Use the Original Adapter: Ensure you are using the official Zosi power adapter that came with your DVR/NVR. These systems and their hard drives require a specific amperage to run correctly.
- Check Connections: Make sure the power adapter is securely plugged into both the Zosi unit and a working wall socket.
### 3. Inspect Internal Connections
If you are comfortable doing so, you can check the physical connections inside the recorder.
- Power Off and Unplug: Completely disconnect the DVR/NVR from power.
- Open the Casing: Remove the screws holding the cover on and slide it off.
- Check Cables: The hard drive is connected to the mainboard by two cables: a wider SATA power cable and a narrower SATA data cable. Unplug both cables from the hard drive and the mainboard and then plug them back in securely. This ensures the connection hasn't worked its way loose.
### 4. Update the System Firmware
Occasionally, a software bug can cause recording errors. Updating your system's firmware can resolve these issues.
- Identify Your Model: Find the exact model number of your Zosi DVR/NVR in the system information menu.
- Download Firmware: Visit the Zosi support website and check if there is a newer firmware version available for your model.
- Update Process: Follow the manufacturer's instructions carefully to update the firmware, usually done via a USB stick.
If you have reformatted the drive, checked all connections and power, and the "Recording Failed" error persists, it is highly probable that the hard drive itself has failed and needs to be replaced. Choose a high-quality surveillance-grade HDD for its replacement to ensure reliability.
