What you'll notice
Clicking or grinding sounds, "HDD Error" warnings, recordings with corrupt or missing segments, or a recorder that hangs on boot.
Why it happens
Age and wear, heat in closed cabinets, power surges, or a desktop-grade drive doing a surveillance job.
How we fix it
We run manufacturer diagnostics, recover what the drive still allows, and fit a correctly sized surveillance-grade replacement — then verify days of clean recording, not minutes.
Still not working?
If the checks above haven't restored your surveillance hard drive, this usually needs a technician. Our CCTV Hard Drive Replacement service covers exactly this fault.
