Specialist work · drive repair

A dead drive never returns to service. What it was holding is a different question.

The bit the repair adverts skip: once a drive has failed, it is finished. Boards and firmware get mended here because that is how you reach the data. Donor heads go in because they last long enough to read the platters through. Nothing is rebuilt to keep. You get back the only part that ever mattered — your files, written to new media.

What genuinely mends, and what a mend actually buys.

Electronics: genuinely fixableFailed PCBs, blown TVS diodes, dead USB bridge chips: properly mendable, and between them the usual explanation for a drive showing nothing at all. The verdict you want.
Firmware: yes, with the right kitA damaged translator or corrupt service-area module leaves a sound mechanism reporting 0GB, or gone from the bus entirely. Fixing that takes purpose-built firmware hardware; no download reaches those structures.
Mechanics: patched for one readTransplanted head stacks, unseized motors, heads eased off a stuck platter: work that buys enough life for a single full read. Once that read finishes, so does the drive.
The end of the board swapAdaptives — calibration values written for that individual drive — live in a ROM chip on its own PCB. Fit a board from another unit and the platters read as nonsense. That trick stopped working roughly two decades back.

How the recovery runs, stage by stage.

01

Logged in, checked at no charge Free

Every item gets its own case number on the day it lands here. An engineer traces the fault, gives you a plain assessment of what is realistically recoverable, and puts one fixed price in writing. The diagnosis is free, you are under no obligation, and chargeable work starts only when you say go.

02

Identify the real fault

Three separate trades hide behind the word 'broken': electronics, firmware, mechanics. The free check says which you have, and what a fix honestly means.

03

Mend it far enough to read

A rebuilt board carrying your own ROM, firmware restored, donor parts where the mechanics gave out — all of it aimed at one complete, clean read.

Hand back what matters

Your data returns checked, indexed and on fresh media. The old disk was never more than the box it sat in. If yours could genuinely handle undemanding use again, we will say so, and we will be equally blunt when it could not.

Played back, checked, handed back

You get the full list of recovered files first, and nothing is charged until you approve it. Data goes back on fresh media, return postage paid, and the job stays open on our side until you confirm every file opens at your end.

What the imager checks first

  • Most people who search for repair want recovery — what they are after is the contents, not a working mechanism. We take the question at face value and give a straight answer.
  • Beware the quiet drive swap — the laptop comes home working beautifully, and the reason is an empty disk fitted in place of yours. Always ask what became of the original.
  • Board faults are the cheap ones — a surge kills the electronics while the platters carry on untouched. That pairing gives some of the quickest, least costly jobs we do.
  • Donor surgery ends a drive's working life — the transplant buys reading time, never dependability. Anyone claiming otherwise is setting you up for a repeat.

In writing, and we'll hold to it: electronics and firmware are genuinely repairable. Heads and motors hold together only as far as the copy. A scored platter is past every lab on earth, whatever an advert says. None of that shifts with age — disks from the IBM, HGST, Hitachi and Fujitsu era still reach this bench. Where a firm offers you a failed drive back in working order, read that offer against their terms and watch it soften.

Lately in the casebook.

A laptop out of 'repair', stripped of everything its owner kept

A Milton Keynes student got a laptop back from the repair shop working perfectly — on a new, empty drive. The original disk, dismissed as dead, had sat clicking in a drawer. Two days of donor-head work later, every essay and photo was waiting on the new drive the shop had fitted.

100% recoveredAfter that 'repair'

While it is still in your hands.

Worth doing

  • Ask any repairer the same question first: 'and my data — what happens to it?'
  • Switch off the moment something sounds wrong
  • Insist on keeping the old disk after any machine repair
  • Include the lot: caddy, board and any snapped parts

Best avoided

  • Source a matching drive and change the boards over at home
  • Point repair utilities at hardware that is dying
  • Trust anything you value to a drive with donor parts
  • Take a booting computer as proof your data is safe

The questions we get asked most.

Is a hard drive ever really repairable?

Boards and firmware, yes — those are properly repairable. Mechanics are different: donor parts buy enough working time to take one copy, and no lab worth trusting would return that drive for everyday use. Either route ends the same way, with your files on new media.

Drive repair versus data recovery — where's the difference?

Repair aims at a drive that works again; recovery aims at the files it held. After a failure only the second is realistic, and that is why certain 'repair' shops hand back a running machine fitted with a new, blank disk.

Does a replacement PCB bring a drive back?

Swapping boards straight over almost never does it. There is a ROM chip on each board holding calibration figures unique to that one drive, and it has to be transplanted onto the donor — soldering work, not a screwdriver job.

Is it cheaper to fix a dead hard drive or buy a new one?

New drives cost very little, and the drive was never what mattered — the files on it were. Spending on recovery to fresh hardware is money that works; spending it on 'repairing' a disk you'd never trust again is money thrown away.

Leave it switched off until it reaches us.

Switch a failing device on again and you lose a little more. Open a case before you do — the diagnosis is free, whatever it finds.
