Troubleshooting / NVR storage

NVR Hard Drive Failure Troubleshooting

A recorder can keep showing live video while storage is degraded or stopped. Treat a disk warning as a recording-path problem, not just an annoying buzzer.

Evidence first: if recordings may matter, do not initialize or format the drive simply because the NVR suggests it. Initialization can erase stored files.

Common symptoms

NVR beeping or showing disk exception / no disk / abnormal status.
Playback gaps even though live view works.
Drive disappears intermittently or becomes read-only.
SMART/bad-sector warnings or unusually slow playback/export.

Diagnostic order

Check the NVR’s hard-drive management page and record the exact status/error.
Confirm the drive is physically detected and its capacity is reported.
Use the NVR’s SMART or bad-sector tools if supported.
Check system logs for disk exceptions and recording errors.
If the recorder is powered down for physical inspection, shut it down through the normal menu first rather than pulling power.

Replacement planning

For continuous recording, use a drive intended for surveillance workloads and confirm the recorder’s supported capacity/interface. After replacement, verify recording and playback on every required channel instead of assuming a “normal” disk status proves the system is recording.

TP-Link’s current VIGI documentation exposes disk status, bad-sector detection and hard-drive exceptions; it also warns that initializing a drive formats it and loses stored files: VIGI NVR user guide.
