What you'll notice
The DVR beeps or shows "No HDD" / "HDD Error"; live view works but nothing records.
Why it happens
A failed drive, a loose SATA or power lead after transport, an undersized PSU, or a desktop-grade drive that has worn out.
How we fix it
We test the drive properly, reseat or replace cabling, and fit a surveillance-grade drive sized for your retention needs — then verify recording and playback before we leave.
Still not working?
If the checks above haven't restored your dvr (digital video recorder), this usually needs a technician. Our DVR Repairs service covers exactly this fault.
