No spin, no light, no sound at all. Total silence is a diagnosis category in its own right — and it’s often better news than a noisy failure, because a silent drive usually means electronics or a seized mechanism, not lost data. The bench establishes which for free, then quotes fixed.

Sacrificed electronics: a power spike hits, and the drive’s protective components on the circuit board die absorbing it — doing their job, leaving platters pristine behind a dead PCB. Seized mechanics: the spindle can’t turn (bearings, or heads stuck to the platter after a knock) — the drive powers but never spins up, sometimes with a faint tick or buzz of effort. Firmware refusal: the drive spins, thinks, and declines to identify itself — alive but mute, its internal software corrupted. Each has a distinct bench route; none is improved by trying other cables, other computers, and other days.
The internet’s favourite dead-drive fix — buy the same model, swap the green board over — stopped working roughly two decades ago. Modern drives store adaptive data on the board: calibration unique to that drive’s heads and platters, written at the factory. A donor board without your board’s adaptives leaves the drive dead or, worse, wobbling through miscalibrated reads. Proper electronic recovery repairs your board or transplants its adaptive chip to a donor — component-level work that returns the drive to exactly itself. If you’ve already tried a swap, no shame: send both boards and everything else in the box.
Often, yes — and it’s one of the better faults to land: a surge usually takes out the protective components on the board while the platters underneath stay untouched. Board-level repair with the drive's own adaptive data carried across, then imaging as normal. Don't test it on another PSU 'to check'.
A buzz or a tick with no spin-up normally means the motor is trying and failing — seized bearings, or heads stuck fast to the platter surface. That's mechanical work, not electronic — and repeated power attempts strain the very components that need to survive. Off, boxed, in.
Sometimes, genuinely — which is exactly why it’s the first two minutes of the free diagnostic rather than something you pay us to assume. External users: the enclosure's own electronics fail more often than the drive inside. Either way you'll know for £0.
