A man in Nuneaton took an old laptop to a repair shop on the high street after a storm knocked the power out twice in an evening. The shop could not get anything off the disk, told him they thought a surge had done it and suggested a specialist. He was open about what he actually wanted, which was the photographs and nothing else: about nine years of family pictures including his daughter's wedding. He had assumed a specialist meant somebody who would try harder with the same tools, and asked what would be different.
| Media | A laptop hard disk a repair shop was unable to read, which they believe was damaged by a power surge during a storm. The owner wants only the photographs from it. |
| What was reported | Old laptop hard disk, two power cuts during a storm, a repair shop tried and could not read it, the shop suspects a surge and advised a specialist, nine years of family photographs the only thing wanted. |
| Fault class | Damage to the circuit board. A surge reaching the drive through the supply takes out the protection components and often a supply rail with them, after which the mechanism receives nothing and the drive is silent. The platters and the heads are on the other side of that failure and are ordinarily untouched. |
| On the bench | The board examined under a stereo microscope with the failed protection component and a burnt supply track identified before anything was powered. A matched donor board sourced, and the memory holding this drive's own calibration values lifted from the original under hot air and refitted to the donor so the numbers matched the mechanism. Brought up on a current-limited bench supply and read behind a hardware write blocker, imaged on DeepSpar behind PC-3000 UDMA, and the photographs located in R-Studio, rendered and checked before release. |
The shop was right about the cause and right to stop. A surge arriving through a laptop's supply passes into the drive's board and the components designed to take that hit are the first to go. That is what they are for. Diagnosing it correctly and declining to go further is a good outcome from a general repair shop, and considerably better than an afternoon of experiments with a bench power supply.
What a specialist has is not more determination but different parts. The answer to a destroyed board is another board, and the difficulty is that a drive of this age keeps values measured for its own mechanism in a small memory on that board. Fit a donor as it comes and the electronics work perfectly while every calibration number is somebody else's, so the drive spins and reads nothing.
Moving the memory across is the standard method, not a trick. The chip is lifted from the damaged board under hot air and refitted to the donor. It is fiddly, it needs magnification and a controlled iron, and it takes twenty minutes. After that the donor behaves as this drive's own board and the mechanism comes up as though nothing had happened.
The photographs were never in the path of the damage. Electricity reaching the board does not reach the recording surfaces, and the heads park when power is lost rather than crashing onto the platters. That is why a surge, alarming as it looks, is one of the better faults to have. The risk in this job was entirely in what somebody might do next with a bench supply and no current limit.
Under magnification the picture was textbook: a transient suppression component failed short, and the track feeding it burnt through, which is the ordinary signature of a surge and matched what the shop had guessed. The memory holding the drive's calibration values sat well away from the damage and was undamaged, which decided the method.
A matched donor board was sourced and the memory transferred under hot air. The drive was brought up on a current-limited supply so the first power-on could be watched rather than gambled on, and it spun, reached speed and identified itself correctly. Imaging ran behind a hardware write blocker on DeepSpar behind PC-3000 UDMA in one clean pass, and R-Studio was used to pull out the picture folders, which were rendered as thumbnails and checked rather than counted.
Nine years of photographs came back, wedding included, and with them a folder of scanned documents the owner had forgotten about that turned out to hold his late father's service record. He was given the pictures organised by the dates the camera had written rather than as one flat folder, which is the difference between a recovery and something usable.
One disk is £300 + VAT. Board work is electronics and named in the published exclusion, so 50% of the figure was settled upfront and the balance once he had seen the wedding pictures.
Unplug the machine and leave the drive alone rather than testing it repeatedly to see whether it comes back. If a general repair shop has already told you they think a surge did it, that is useful information worth passing on, and you should ask whether they powered the drive after they formed that view. Do not buy a matching board online and fit it, because on anything made in the last twenty years the replacement arrives with the wrong calibration values and will not work, and the money is wasted. Keep the original board whatever happens, since it holds the only copy of those numbers and no laboratory can invent them. Never put a drive with visibly burnt components onto a supply that has no current limit. If it is a laptop drive, take it out and send the bare disk rather than the machine, and mention the storm, because a surge case and a wear case are opened with different expectations.
What this job cost, and on what terms. This one was charged at £300 + VAT, the figure agreed in writing before any work began. Paying for a job like this one. This file sits in the half the guarantee does not reach. Four sorts of work are excluded from no fix, no fee and there are no others: DVR jobs, forensic jobs, chip-level work, and electronic or mechanical failure. On any of them half the quoted figure is settled before the bench starts, with the remainder due when the files go back. Everything outside those four — a deletion, a formatted card, a broken file system, a lost partition, and firmware or service-area repair, which counts as logical however it sounds — runs under no fix, no fee, so an attempt that fails costs nothing.
If yours is doing the same thing. This drive was read at Oxford Data Recovery on the Oxford Science Park, about fifty-five miles down the M40. Post it tracked and insured, send it by a courier you book yourself, or bring it to the Oxford reception during Mon–Fri 9:00am–5:30pm — there is no collection service and no counter in Coventry. The free look at it takes two working days from booking in and produces one written figure that then holds.
Freephone 0800 689 0668 to talk it through first. The shipping form and what goes in the parcel are on the contact page, and every band is published in full — including which work sits outside no fix, no fee.
These are real enquiries, from households and from businesses in Coventry and out across Warwickshire — Nuneaton and Bedworth, Rugby, Leamington Spa, Warwick, Kenilworth, Solihull, Stratford-upon-Avon, Atherstone and Southam. Names are gone: the customer, the company, the job title, anything at all that would point back at a person. What stays is the reasoning — what turned up, where the fault genuinely sat, which approach it demanded, and which machine on the bench did the work. One of the thirty-six was refused, and it earns a place here as squarely as any of the rest.
Scoring removes the magnetic layer, so the honest question is how much of the surface it missed
A replacement board without the original ROM is a stranger's brain in the wrong body
A quoted chance of fifty-fifty is an honest way of saying the answer is in the geometry
