Case Study · CCTV Data Recovery
A Western Digital 250GB IDE drive, ten years inside a CCTV system.
A decade of continuous recording finally caught up with this drive, brought into our Belfast laboratory after it began developing bad sectors. The ageing hardware turned out to be the easy part — reconstructing watchable footage from it was the real job.
The case
A drive well past its expected lifespan.
This Western Digital 250GB IDE hard drive had been running continuously inside a CCTV recording system for more than ten years before it was brought to our lab on the Ormeau Road, Belfast.
Ten years of continuous duty is a long service life for any mechanical hard drive, and this one was showing it: bad sectors were developing and performance was steadily degrading — the classic pattern of a drive nearing the end of its life.
IDE is a legacy interface, long since superseded by SATA, but it is still common inside CCTV recorders and DVRs of this age. We keep IDE adapters in stock specifically for cases like this one, so connecting and imaging the drive in our lab was never in question.
The recovery
Getting the data off the drive was the easy part.
Recovering data from a failing CCTV drive is only half the job. The harder problem is turning what comes off it into footage anyone can actually watch.
- 01
Diagnosis
The drive was assessed and the developing bad sectors confirmed as the cause of its decline, before any recovery work began.
- 02
Imaging via legacy IDE connection
Connected using one of our in-stock IDE adapters and imaged to pull the raw data off the degrading platters intact.

Raw-to-video reconstruction
Most CCTV and DVR systems record in their own proprietary raw format. Getting the raw data back is not the same as getting usable video — the device-specific codec then has to be applied to reconstruct playable footage from it.
The result
Footage recovered, at a fraction of a replacement system's cost.
The raw file format was the biggest obstacle in this case, taking several hours of additional work to convert the recovered data into usable video streams.
Total cost for the recovery came to around £190 + VAT.
Some newer CCTV recorders add hardware encryption on top of this, which adds further labour and cost. Cheaper CCTV recording systems can be genuinely good value for money — but if the drive inside one fails, recovery is often more involved, and more costly, than for a straightforward desktop or laptop drive. It is worth reading the specification carefully and choosing a system with that trade-off in mind.
Power it down and get an honest recoverability view and fixed quote before any work begins — whatever the age, brand or interface.
