On the bench · hard drive repair
Most calls open with the same question: can it be fixed? Partly. A dead board mends, and so does firmware that has lost track of itself. Heads and motors are borrowed parts that last one careful read, no more. Drives are posted in from Hull, Beverley, Bridlington and the rest of the East Riding, and from Grimsby and Scunthorpe over the Humber, and every job finishes the same way: your files written onto media bought new for you.

| What you see | What the fault is | What to try |
|---|---|---|
| It is clicking. Can that be fixed? | Heads have failed. A donor set holds long enough for one clean pass, and the drive is scrap after that | That is recovery, not repair |
| Dead quiet, nothing at all | Usually a shorted TVS diode or a dead board. Electronics — and a genuine repair | Fix the board, then image it |
| Reports 0GB, or claims to be a different drive | A corrupt translator or service-area module. This one genuinely repairs | Repair the firmware, then read it |
| The socket has sheared off my portable drive | A real connector and bridge repair. On WD portables the encryption sits in that same bridge chip | Post it whole, case and all |
| A repair shop says it is now 'fixed' | Ask what they actually changed. An empty drive in place of yours is no use to you | Do not just take their word |
| Is a donor board not the cheap answer? | Its ROM holds adaptives matched to one drive only, so a donor board left alone reads back rubbish | Your own ROM has to move |
Each item that arrives gets a case number the day it lands. An engineer looks at it and finds the real fault, and that costs you nothing. You are told in plain terms which files can come off the drive and which cannot. A price follows — one figure, written down. No work starts until you have seen it and agreed to it.
Drives fail in three places: the electronics, the firmware, or the moving parts. One word covers all three, which helps nobody. The free look tells you which one you have, and what repairing it would mean.
Your ROM moved to a rebuilt board. The service area put right module by module. Donor mechanics where the originals gave out. All of it aims at one thing: an unbroken read of the platters, first sector to last.
Whatever comes off is checked, listed, and written to media bought new for your job. The drive was only ever the container. If it is still good for light use we will tell you, and if it is done we will tell you that too.
You are not billed while you are still thinking. The list of what came off the drive goes to you first, and the invoice waits on your word. Files go home on media bought in for the job, with the postage back on us. We keep the job open until you have opened them on your own machine.
Written down, and held to: boards and firmware do mend. Heads and motors are patched to survive one copy and not an hour more. A scored platter is unreadable — here, and in every other lab, whatever an advert says. None of that has changed, and drives with IBM, HGST, Hitachi and Fujitsu on the label keep arriving from Hull, Beverley, Bridlington and Grimsby. Where a firm promises to return your failed drive fit for use, set that promise beside its own small print and see what is left of it.
The shop handed the laptop back working, a new disk fitted and empty. The old one, written off as beyond help, sat clicking in a drawer in a Hull student flat. It got donor heads. Two days on, the essays and the photographs went onto the shop's new disk.
Some of it. The board and the firmware genuinely mend — a rebuilt PCB, a service area straightened out. Anything with moving parts is another story. Donor heads are fitted to do one thing: survive a single pass over the platters. After that the drive is scrap and does not go back in the post. The files do, on media we buy in.
A repair is about the hardware — the customer leaves with a working device. Recovery is about the contents, and the hardware is treated as disposable. When a disk has genuinely failed, only the second answer is honest. It is why a laptop can come back from a shop quick and quiet, with none of your files on it.
Almost never, and never by itself. A small ROM on the board carries adaptive values measured against your mechanism alone. Move that chip onto the replacement and the drive reads. Leave it behind and the heads return noise. That is a soldering job, and it needs the right bench and the right kit.
Cheap drives are exactly why the comparison fails. Nobody is selling you a drive here. The charge is for what was on the one that stopped, handed back on hardware that works. Put the same money into keeping the failed disk alive and you end up with a part you would not trust with anything.
Leave it switched off. A failing drive has a limited number of starts in it, and each one spends a little more. The free diagnosis will say which files can be read.
