No lights, no vibration, no sound. It feels like the worst outcome and it is usually among the better ones — complete silence points at the circuit board far more often than the mechanism, which means the platters and everything on them are untouched behind electronics that stopped working.

A drive that does nothing at all is more often electronically dead than mechanically damaged — and that means the platters, and your data, are untouched behind a failed board. Resist the urge to fit a replacement board from an identical model; on any modern drive that alone will not work.
No lights, no vibration, no sound — and four quite different causes behind it.
This is the single most common piece of well-meant advice that costs people their data.
Since roughly 2005, drive boards have stored adaptive calibration data unique to that individual drive — head resistance values, preamp settings, defect maps — in a small ROM chip on the board. Those values describe that specific mechanism and no other. Fit a donor board without transferring the original ROM and the drive either does nothing, or attempts to operate the heads with the wrong calibration, which can cause real damage.
A board-level repair therefore means either repairing the original board or transplanting the ROM onto a matched donor. It is routine bench work with the right equipment. It is not a home procedure, and the advice to buy the same model second-hand is a decade out of date.
Silence gives little away, so the work is systematic.
Different cable, different port, different power supply. On externals a failed power brick or bridge board is a frequent culprit, and eliminating those costs nothing.
Burn marks, blown TVS diodes and failed components are often visible. A shorted protection diode is a good sign — it means the surge stopped there.
The original board is repaired where possible; otherwise a matched donor is fitted with the original ROM adaptives carried across.
Seized motors mean transferring the platter pack to a donor chassis with alignment preserved. Stiction means freeing the heads under filtered clean air.
Once the drive responds, it is cloned read-only straight away. A revived drive is not a reliable drive, and the objective is one good read.
Board work and mechanical work are priced the same way.
A single drive that will not power on is from £300 +VAT, confirmed in writing after a free 48-hour diagnostic. Most jobs are no fix, no fee; where the drive must be opened in clean air or fitted with donor parts, there is a 50% deposit with the balance payable only on success.

Send the device in for its free diagnostic and tell us briefly what happened; an engineer reviews it and confirms your exact quote in writing before anything starts.
Getting your data back begins with getting the device to us. Pack it up safely, pop your contact details inside, and send it over — once we’ve run the free diagnostic, we’ll confirm your exact price in writing before any work starts.
Posting it? A tracked, insured service is what we’d recommend. Rather drop it in? You’re welcome Monday to Friday, 9am to 5:30pm — just package the device up as above first.

When a drive draws no power whatsoever — no spin, no click, silence — it has usually lost its circuit board rather than anything mechanical: one surge, or a reversed adapter, can take out the board’s protection diode in a heartbeat. Repairing that electronics is genuine bench work, a world away from the board-swap of internet myth — a modern PCB carries drive-specific calibration in a ROM chip, so a donor board only comes alive once that chip, or its contents, is carried across. Done right, a surge-killed drive frequently reads back in full. Our case files hold a recent one: a WD Red Recovery: Spinning, but Not Recognised, recovered by precisely this method.
The questions we field most about dead, won’t-power-on drives.
Usually not. Complete silence is more often electronic than mechanical, which means the platters and your data are intact behind a failed board. It is among the more recoverable categories of failure.
Not on any modern drive. Boards hold adaptive calibration data unique to that individual drive in a ROM chip, so a donor board must have the original ROM transferred first. Without that the drive either does nothing or operates with wrong calibration, which can cause damage.
A protection component on the drive board that deliberately shorts out to absorb a power surge. It kills the drive in the process, which is exactly its job — and it means the surge stopped at the board rather than reaching the mechanism. Good news, as these things go.
The power supply first, particularly on 3.5-inch desktop units with an external brick, then the cable and port. A surprising number of apparently dead externals are dead power supplies, and eliminating that costs nothing.
That points at the motor rather than the board — a seized bearing or heads bonded to the platter. Different fault, same instruction: stop attempting it, because repeated tries can tear a head from its arm.
