Drive repair · the mendable and the finished
One drive, £300 + VAT — a single figure, written down, after a diagnosis nobody charges you for. Two jobs answer to the same word and the money buys the second of them: one mends hardware, the other lifts the contents clear, and files only ever return from the second. Boards mend. Firmware mends. Platters, motors and head stacks are a different story: propped up for one pass over the surfaces, then retired. Disks reach the bench from all over London, Hammersmith, Barnet, Ealing and Southwark among them, and every one of them finishes the same way — your data, written to media bought new for the job.
Put it to an engineer — the first look costs nothing

| What is going on | The usual reason for it | Where that leaves you |
|---|---|---|
| There is a click, or a tick. Can that be mended? | A head crash. That stack is finished, and donor heads last one sweep of the surfaces, no more | Recovery territory, not repair |
| No light, no noise, no response | The board, nearly every time: a TVS diode shorted through, or electronics finished. A true repair | Board mended, then cloned |
| It reports 0GB, or answers to another model's name | Corruption in a service-area module, or in the translator. Firmware, in other words, and firmware mends | Firmware corrected, then imaged |
| The USB socket has broken away from a portable's board | Socket and bridge board — and where the portable is a WD, that bridge chip holds its encryption keys | Send the whole thing, enclosure too |
| A repair shop now calls it 'working' | Ask which part they changed. A blank disk where yours used to sit hands you nothing | Ask that before any money moves |
| Can a cheap donor board off eBay do it? | The adaptives in its ROM belong to another mechanism, so a donor fitted from the packet reads noise | The ROM from yours must be moved over |
A case number goes on it the day the parcel lands, and an engineer settles what has truly failed before anything else happens — free of charge, and first in the order of work. Back to you come two things together: a straight note of what is liftable and what is not, plus one figure, fixed and written down. Accept it, or decline and owe us nothing.
Three unrelated things stop a disk: the electronics, the firmware, and the mechanism turning inside. Each of them answers to the words broken hard drive, which is how two quotes against a single symptom finish hundreds of pounds apart. Deciding which one you are actually holding is the whole purpose of the free diagnosis, and it comes ahead of any figure.
The ROM off your own board is transferred to a rebuilt one. Corrupt service-area modules get put right individually. Where an original mechanical part has failed, a donor part stands in. All of it serves a single end: one sweep across the surfaces, beginning to end, uninterrupted.
Everything lifted clear is verified, listed, and written to media purchased new for your job. Holding that data was all the drive was ever doing. What will not happen is the drive going back into service: its mechanism has made its final read, and you are told as much plainly.
What was recovered is listed for you first, and only then does a bill exist. Approve the list and it is invoiced; turn it down and it is not — and where nothing has come back, most jobs carry no charge whatever. Recovered data travels home on fresh media bought in for your job, with the postage at our end. Your case is not closed until you have read those files on a machine of your own.
Set down here, and held to: a board is an ordinary repair and so is firmware. Mechanical parts are borrowed for exactly one copy. Scour the coating off a platter and what was underneath it does not return, in this laboratory or any other, however the advertising is worded. Those three lines have not altered in years, and badges from Seagate, Toshiba, Western Digital and Hitachi keep arriving out of London, Wandsworth, Hackney and Islington. One disk sits at £300 + VAT, put in writing when the free look ends, and most jobs carry no fee where nothing is recovered. Should some firm offer to give you the broken drive back in a state fit for daily use, hold the offer up against that firm's small print and count what is left.
A repair shop told her the 1TB Seagate out of her Dell was no good and that her files could not be got back; it fitted a new drive and, to its credit, handed the old one over. Such a verdict describes that shop's own bench. Here the disk went onto PC-3000 so the real fault could be named, was imaged behind a write blocker, and her photographs and emails were read out of that image.
In part. Boards mend, and so does firmware: a rebuilt PCB carrying the ROM lifted from your own board, and a service area repaired one module at a time. Mechanics are another matter altogether. A donor head stack has exactly one job — holding together while the platters get read through once — and out it comes when that read finishes. Your data goes home. The drive itself does not.
Repair hands you back hardware you can go on using. Recovery hands you the files and gives up on the hardware. Where a disk has truly failed, only one of the two can honestly be promised, and the other is why a laptop can come out of a cheap fix running beautifully with none of its owner's work aboard. Nothing there was mended; a disk was exchanged for another.
Rarely, and never on its own. Adaptive values sit in a board's ROM, and they were measured against a single mechanism — yours. Move that chip across and sensible answers start coming back; fit a donor board untouched, straight from its packet, and the heads give you noise. Moving it means desoldering, and desoldering means a bench equipped for it.
Because a disk is not the thing being bought. For £300 + VAT you get whatever the stopped drive was holding, handed back on media that works. One figure, set down in writing as soon as the free diagnosis ends, with most jobs carrying no fee where nothing is recovered. Spend the money coaxing a failed mechanism along instead and you end up owning a component you would never trust again.
Looking at it is free. Back comes a list of what opened and what did not, together with a single price to finish, set down in writing while you are still free to say no. On most jobs an invoice only follows the data. Until that list reaches you, leave the drive switched off.
