A wedding and function DJ working across Coventry had his laptop shut down on its own during a Friday setup. On the restart it announced that there was no operating system, and he tried again perhaps a dozen times before he noticed a noise from inside that he had never heard before, a soft repeated click. A friend told him to stop immediately, which was the best advice he got all week. He had two bookings that weekend and about eleven years of tracks, edits and set lists on the machine.
| Media | An ageing laptop that shut down without warning and now reports no operating system on every restart, with a repeated clicking audible from the disk. It holds a working DJ's music library and set lists. |
| What was reported | Old laptop, powered off unexpectedly, reports no operating system on restart, tried a dozen times, a new clicking noise from inside, a friend advised stopping, music library urgently needed for weekend bookings. |
| Fault class | Head failure. The clicking was the head assembly moving to a reference position, failing to read it and retrying, and a disk that cannot read its own service area cannot read anything else either. That is why the machine found no operating system on it. The recorded surfaces were expected to be intact if the retries stopped. |
| On the bench | Not started again after arrival, since a clicking disk is a head assembly repeatedly striking a limit. Taken out of the laptop and profiled on a current-limited bench supply so the retry pattern could be read as a trace rather than listened to. Opened under laminar flow with the head assembly, the landing zone and both surfaces examined under a stereo microscope. Matched donor heads fitted and the alignment set, then imaged on DeepSpar behind PC-3000 UDMA with the head map watched, and the music library located in R-Studio and played before release. |
The message on the screen was about the disk, not about Windows. A machine looks for a boot loader in a specific place and reports no operating system when it cannot read one. That happens if the software is genuinely missing and it also happens if the disk cannot deliver a single sector. From the outside those look identical, which is why the same message sends some people to a reinstall and others to a laboratory.
The clicking settles the argument instantly. Software does not click. That sound is the head assembly swinging to a reference track, finding nothing it recognises, retreating to a stop and trying again, and the regularity of it is the giveaway. A drive that has lost its software is silent. A drive that clicks has a mechanical problem and nothing installed on it will fix that.
A dozen restarts is roughly the point at which luck runs out. Each attempt drags a failing head across the surface and each one has a chance of taking a piece of the recording layer with it. He stopped at twelve because a friend told him to. Owners who keep going through an evening, on the reasonable theory that it might catch, are the reason some of these jobs come back partial.
The service area is the piece most people have never heard of. Every disk keeps its own configuration on the platters in a reserved region, and it reads that before it will speak to the machine at all. Damaged heads cannot get to it, so the drive never introduces itself and every layer above assumes there is nothing there. The library is untouched a few millimetres away the entire time.
The disk came out of the laptop and went onto a current-limited supply, never near a host machine. The trace showed a spin-up to full speed followed by a repeating pattern of seek attempts, which is a head fault rather than a motor or supply problem and ruled out the cheaper possibilities in about a minute.
Under laminar flow one head was visibly damaged at the slider and a second was contaminated. Both surfaces were checked at magnification across the full radius, which found light marking on one platter over a narrow band and nothing elsewhere, a good result for twelve attempts. Matched donor heads went in, the alignment was set, and imaging ran on DeepSpar behind PC-3000 UDMA with the marked band left until last. R-Studio then read the filesystem from the image.
The library came back, tracks, edits and set lists together, along with the folder of client requests that mattered more to his business than the music did. About forty files sat on the marked band and came back damaged; they were listed, and all but three could be replaced from the shops he had bought them from.
One disk is £300 + VAT. Opening it and fitting donor parts is physical work under the published exclusion, so 50% of the figure was settled upfront and the balance once he had played a sample himself.
Stop restarting it. The temptation is enormous, because each attempt takes ten seconds and might be the one that works, but a clicking disk is a mechanism failing repeatedly against a surface and the odds get worse with every try rather than better. Do not boot from a recovery stick and do not run the repair option, since both write to a disk that cannot reliably read. Do not reinstall the operating system, which is the single suggestion most likely to be made to you and would put fresh files exactly where your own ones are. If the disk is in a laptop, take it out and send the bare unit rather than the machine. Say how many times it was restarted after the noise began, because that number bears directly on how much surface damage the bench should expect to find.
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.
A tone instead of a spin-up is a motor drawing current it cannot turn into movement
An interrupted installation overwrites the front of a disk and leaves the rest of it alone
