Free online diagnostic

Four short steps — device, maker, symptom — and out comes an engineer's read-out: the likely fault, the thing to do this minute, and how long that repair normally runs to. Leave your details and it gets confirmed personally, as soon as we can.

Instant read-out Free here and on the bench Fixed quote before any work No fix, no fee

Finding out costs nothing — not online and not on the bench. Money only enters it once you approve a fixed quote, and on most jobs only if the recovery works.

The exact figure goes into writing once the free diagnostic is done — finding out costs you nothing. No fix, no fee covers logical recoveries (deleted, formatted or corrupt data); drives with electronic, mechanical, physical, water or fire damage need invasive work, so 50% of the quote is payable upfront — and every bit of that is set down in writing before anything is touched.

  • Is the drive still in a computer, laptop, MacBook, iMac, CCTV / DVR or server? The hard drive or SSD has to come out and travel on its own — taking drives out of machines is not a service we offer, and it is rarely more than a few screws. Storage soldered to a motherboard (Apple Silicon Macs, one or two thin laptops) is the single thing we cannot accept: removable drives only.
  • Anti-static bag or bubble wrap, then a firm box packed so nothing shifts about. Leave the cables and power bricks at home.
  • There is no collection service: send the device tracked and insured, put it with a courier of your own, or bring it to reception yourself, Mon–Fri 9am–5:30pm.
  • Print the booking-in and shipping form, add your name and number, and put it in the box so the device is logged the moment it arrives.

// what recovery costs

Plain figures, fixed in writing

Nearly everything that lands on the bench falls into one of three fixed bands — the device sets the price, not how desperate the situation is. One written figure follows the free diagnostic. Logical recoveries are no fix, no fee; drives with electronic, mechanical, physical, water or fire damage need invasive work, so 50% of the quote is payable upfront (see below).

£250 + VAT

USB sticks and memory cards — SD, microSD and CF.

£300 + VAT

A single hard drive or SSD — internal or external, laptop, desktop or Mac.

From £500 + VAT

RAID, NAS and servers — imaged and rebuilt per drive, priced to the job.

CCTV / DVR recorder drives are a fixed £400 + VAT, and a standard forensic investigation is £800 + VAT, payable 100% upfront (larger cases scoped and quoted in writing). No fix, no fee applies to logical recoveries — deleted, formatted or corrupt data, or a healthy drive the system just can't see. It does not apply to drives with electronic, mechanical, physical, water or fire damage: those need invasive work — a new PCB or controller, head/motor repair, NAND chip-off or firmware/service-area access — so 50% of the quoted price is payable upfront for the donor parts and lab time. Jobs at the difficult end — a board burnt beyond reading, media snapped through, a rebuild spanning a whole shelf of disks — sit above those bands. The figure for those is written down after the free diagnostic, and nothing starts until you have seen it.

// what the bench diagnostic checks

What "free diagnostic" means here

When your device arrives it gets a proper engineering examination, not five minutes with a free scanner. Within 2 working days you will have answers on all six of these:

01 · Power & electronics

The electrics are looked at first: board, bridge and power rails checked over, and the drive's one-of-a-kind ROM secured before anything else happens.

02 · Mechanical health

Heads, spindle motor and platter surfaces are judged before the drive is asked to attempt a single difficult read.

03 · Firmware state

Service area and translator inspected on the PC-3000 — the layer where faults sit completely invisible to ordinary software.

04 · Media integrity

A measured read on hardware imagers shows how much of those platters or NAND chips will genuinely hand data over.

05 · File-system state

The file system is mapped out: what is whole, what is damaged, and which of your actual folders are coming home.

06 · Your fixed quote

One figure for the recovery, priced against the real fault. Take it or leave it — you owe nothing either way.

// diagnostic questions

Common questions

Free twice over. The read-out on this page costs nothing, and neither does the engineer's assessment once your device is on the bench. The only decision with money attached is whether you accept one fixed written quote, and on most jobs a recovery that fails costs you nothing at all.
Choose 'Other / not sure' and press on; it makes no odds. What you pick simply gives the engineer a head start before the parcel turns up. The assessment that decides matters is the bench one, finished 2 working days after the drive reaches us.
Read it as a first opinion from somebody who has met those symptoms a few thousand times over. Each maps to its usual cause, to the thing worth doing immediately, and to an honest timescale. The bench work then names the exact fault and fixes your price.
Not in the least. An engineer rings you back first and you talk it through. If you would sooner skip the conversation, wrap the device up and send it directly to our Cambridge location.
// getting your device to us

Getting it here — no great performance

Most of what reaches this bench arrived by tracked, insured post. It is the steadiest way to move a poorly drive, and a parcel posted in Norfolk is usually on the bench the next working day.

Is the drive still bolted inside a laptop, desktop, MacBook, iMac, server or CCTV / DVR recorder? The hard drive or SSD needs to come out first, and only the bare drive travels — taking drives out of machines is not something we do here. Storage soldered to a motherboard (Apple Silicon Macs, one or two very thin laptops) is the single thing beyond us: if it will not come out, it cannot come in.

  • Bubble wrap and a firm box or padded envelope, packed so nothing shifts about. Cables, caddies and power bricks are no use to us — keep them.
  • Print the shipping & booking-in form (PDF), write your name, your number and a couple of lines on what happened, and put it in with the drive.
  • Royal Mail Special Delivery covers it tracked and insured door to door; a courier of your own does the same job if that suits you better.
  • Rather hand it over yourself? Reception at the address below takes drop-offs, Mon–Fri 9:00am–5:30pm.

Mark the parcel for the attention of Cambridge Data Recovery. From Norwich it is about an hour and twenty down the A11, then two minutes off the A14 at Junction 32 — or next working day by tracked post. You hear from us as soon as it is booked onto the bench.

Unsure what to put in the box? Ring 0800 689 0668 before you seal it, or run the free online diagnostic.

Rather just post it?

Wrap it properly, put a note with your name and number in the box, and send it tracked.
