When a drive won’t spin up or power on, the trouble is nearly always electronics or the motor — not the data. Our engineers mend the failed board, carry the firmware over, and recover your files on site.

Keep putting power through a drive with an electrical fault and you risk burning out the motor or worsening the board damage. And don’t fit a replacement board yourself: the unique calibration data modern drives keep on a ROM chip has to be transferred first, or the drive may be beyond saving. Power it off and get in touch.
Nine times out of ten, a silent, dead drive comes down to an electrical or motor fault. Here are the causes we diagnose — and reverse — most.
Bringing dead drives back to life since 2002, we have covered every major brand. If your data sits on spinning platters, the odds are good we can help.
SATA, SAS, IDE/PATA and SCSI · internal and external · 3.5" desktop and 2.5" laptop · from 40 GB legacy drives up to today’s 24 TB helium models.
A won’t-power-on drive is revived from its electronics outward. We bring it up safely first, then read your data off — gently, following a set order.
Drop the drive in or post it over. We pin down whether the board, the motor or the power supply is at fault, then send a written quote, normally within 48 hours.
Under magnification the board is checked for shorts, blown diodes and burnt components — and with external drives, the enclosure is bypassed so the bare drive is tested directly.
Blown diodes and failed components are replaced, or a matched donor board is pulled from our parts store, with no weeks lost waiting on one.
Across to the donor board goes the original ROM chip, so the drive reads its own calibration data and powers up as it should.
Once it powers on, the drive is cloned sector by sector onto stable storage, worked patiently around any weak areas.
From that image your files are rebuilt, verified against a file listing, and handed back on fresh media.
Your data comes back on an external drive by insured post, or — for up to 75GB of it — as a free download.
Boards, ROMs, motors and heads all matched on site mean a won’t-power-on drive can usually go straight into repair — no weeks lost chasing a donor.
Tell us about your drive and we’ll come back to you, usually within half an hour during the working day.
We’ll be in touch shortly. If it’s urgent, call 01483 901310.
No surprise fees and no pressure — a free diagnostic and a written quote come before any work starts.
A few recent won’t-power-on jobs, every one done in-house. Identifying details stripped, results confirmed.
A shorted board with a blown TVS diode. A donor PCB was matched from stock, the original ROM chip moved across, and the first imaging pass ran clean.
A failed USB bridge was the fault, not the drive. We bypassed the enclosure, wired the bare drive in, and it proved perfectly healthy.
The board had a burnt motor controller. A matched donor PCB went in, the firmware carried over, and the full volume came back.
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.
Want a bit more detail first? Fill in the form with more about your issue and an engineer will review it and send you a custom quote.

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 Western Digital knocked out by a power surge, recovered by precisely this method.
The questions we field most about dead, won’t-power-on drives.
Nine times in ten it’s the electronics — a burnt motor controller, a blown protective diode or a failed circuit board — not the data. Since the platters holding your files usually come through completely intact, these drives are recoverable far more often than people expect.
No. Each retry on a drive with an electrical fault risks burning out the motor or making the board worse. Turn it off, unplug it and get in touch — less power through it means better odds.
Usually. The failed board gets repaired or a matched donor fitted, the drive’s firmware moved across, and then it’s imaged and your files rebuilt. A drive that looks utterly dead is routine work for us.
Better not to. The ROM chip on a modern drive’s board carries unique calibration data, and dropping in a donor board without carrying that chip across usually leaves the drive unreadable — a simple repair turned into a much harder one.
Frequently not. With externals the real fault is often the power adapter or the USB-to-SATA bridge, not the drive at all. Bypass the enclosure, wire the bare drive in, and more often than not it’s fine.
A won’t-power-on hard drive is £300 + VAT, flat. You get a free written diagnostic first so there are no surprises, and most jobs run no fix, no fee — with a parts-and-labour fee applying only where a board needs sourcing or the spindle has seized.
With the quote approved, most won’t-power-on jobs wrap up within three to four working days, and the diagnostic alone is usually done inside 48 hours. Genuinely urgent ones can be moved up — just say.
All the major makers — Seagate and WD through Toshiba, Samsung, HGST and Hitachi, on to Maxtor, Fujitsu, IBM, Quantum, LaCie, SanDisk, Buffalo, G-Technology, Iomega, Verbatim, Transcend, ADATA, Silicon Power, Intenso, UnionSine and ModusTech — covering desktop 3.5-inch, laptop 2.5-inch and external builds.
Either drop it at our Guildford point on a weekday between 9am and 5:30pm, or post it fully insured. Package it well and slip your details inside — name, address, phone and email — so it can be booked in. The free diagnostic starts once it lands, and a written quote follows before any work.
Behind every repair a 10,000-part store, a free written diagnostic to open, and no fix no fee on most jobs. Begin your recovery today.
