Recovering a failing PC that ran a charity's air-conditioning

The challenge

A national health charity had an old Windows desktop doing an unglamorous but important job at its head office: running the control system for the building’s air conditioning. The machine was around ten or eleven years old, and its hard drive had started to fail — plugged into another computer it was visible, but it wouldn’t read its contents or open the file structure, and it would no longer boot.

The software and its settings lived on that one drive. They needed the data recovered and the machine brought back to a working, bootable state — not rebuilt from memory.

What we did

The PC was couriered to our team and we ran full diagnostics on the drive:

• Diagnosis first — we confirmed the drive was faulty. The file structure could be repaired, but the disk had a bad sector in the system area, and bad sectors on a main system drive can’t be repaired. That meant the old drive could never be trusted to boot reliably again.
• Clone, don’t reinstall — rather than wipe and start over (and lose the configured software), we cloned the operating system, applications and files across onto a new SSD.
• Repaired the boot — we then repaired the operating system on the new drive so the computer started up exactly as it had before, with everything kept intact.

We gave the charity a straight assessment and a fixed price before doing the work, so there were no surprises.

The result

The desktop came back from the brink: a healthy new SSD in place of a dying decade-old disk, the same setup the team was used to, and a machine that boots properly again. The staff on site could control the building’s air conditioning once more — and the charity avoided rebuilding a bespoke setup from scratch.

It’s also a reminder of why a backup matters: a single ageing drive was all that stood between the charity and losing that system for good.

Honest about who did the work

This work was delivered by our team. We’ve anonymised the client out of respect for their privacy — but the failure, the fix and the outcome are real. Rescuing data from a dying drive, and putting a machine back on a healthy disk, is exactly what our data recovery, SSD upgrade and backup & continuity work is for.
