Free online diagnostic

Four short steps (device, maker, symptom) and out comes an engineer's read-out: what is likely to be wrong, what needs doing now and how long that repair normally takes. Leave your details and we'll confirm it with you personally, as soon as we can.

Instant read-out Free here and on the bench Fixed quote before any work Pay only if we recover your data
▲

There are no charges to find out, not online and not on the bench. Money only comes into it once you approve a fixed quote, and in most cases you only pay if we recover your data.

Send us your device

Once the free diagnostic has been completed, the exact price is put in writing, and there is no cost to find out. In a logical recovery (deleted, formatted or corrupted files), you only pay if we recover your data. Drives with electronic, mechanical or physical damage, or exposure to water or fire, need invasive procedures, so 50% of the quote must be paid before we start, and the remaining balance is only due if we recover your data. All of it is put in writing before anything is touched.

  • Is the drive still in a computer, laptop, MacBook, iMac, CCTV / DVR or server? Send the drive alone, not the machine, as the hard drive or SSD needs to be removed and travel separately. Typically it will be no more than a couple of screws. With a CCTV / DVR recorder, send the disk and not the recorder itself. Server and RAID disks come out, each labelled by its bay. NAS disks come out if possible, but if you can't, then send the NAS. We cannot accept storage that has been soldered onto a motherboard (Apple Silicon Macs, one or two thin laptops): removable drives only. If you're not sure which kind you have, ring us first.
  • Put it in an anti-static bag or bubble wrap and then into a firm box so nothing moves about. Do not include cables or power supplies, unless you are sending a single external hard drive, which comes whole with its cable and power supply.
  • Get a quote from us first. There is no collection service. Send it tracked and insured at your own cost, use a courier of your own, or drop it off at reception yourself, Monday to Friday, 9am to 5:30pm. No appointment needed.
  • Print the booking-in form, fill in your name and phone number and put it in the box with the device. This way, it is logged the moment we receive it.

// what recovery costs

Plain figures, fixed in writing

The majority of jobs on the bench fall into one of three fixed bands. The device sets the price, not how desperate the situation is. After the free diagnostic there will be one written figure. On logical recoveries you only pay if we recover your data. Drives with electronic, mechanical, physical, water or fire damage need invasive work, so half of the quote is paid before proceeding, and the balance only if we recover your data (see below).

£250 + VAT

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

£300 + VAT

One hard drive or SSD, internal or external, from a laptop, desktop or Mac.

From £500 + VAT

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

CCTV/DVR recorder drives are a fixed £400 + VAT, and a standard forensic investigation is £800 + VAT; in each case you pay upfront once you accept the fixed quote (larger cases are scoped and quoted in writing). On logical recoveries you only pay if we recover your data: deleted, formatted or corrupted data, or a healthy drive the system simply cannot see. Drives with electronic, mechanical, physical, water or fire damage are different: they 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, and the remaining 50% only if we recover your data. Jobs at the difficult end (for example a board burned beyond reading, media snapped through, or a rebuild across a whole shelf of disks) sit above those bands. The figure for those is written down after the free diagnostic, and nothing will start until you have seen it.

// what the bench diagnostic checks

What "free diagnostic" means here

Every device is given a proper engineering examination, not a 5 minute scan with a free scanner. Within 2 working days of arrival you will have answers on all six of these:

01 · Power & electronics

First, we look at the electrics: the board, bridge and power rails are checked, and the drive's unique ROM is secured before anything else happens.

02 · Mechanical health

The heads, spindle motor and the surface of the platters are checked before the drive is asked to perform a single hard read.

03 · Firmware state

The service area and translator are inspected on the PC-3000, where faults are hidden from view by normal software.

04 · Media integrity

A measured read on our hardware imagers shows how much of those platters or NAND chips will actually give up data.

05 · File-system state

The file system is mapped: what is whole, what is damaged, and which of your actual folders will make it back to you.

06 · Your fixed quote

One price for your recovery, set against the actual fault. Take it or leave it; either way you owe nothing.

// diagnostic questions

Common questions

No cost, twice. There is no charge for the read-out on this page, and the engineer's assessment costs nothing when your device arrives on the bench. The only decision with money attached is whether you accept one fixed written quote, and in most cases you only pay if we recover your data.
Choose 'Other / not sure' and carry on; it makes no difference. What you pick just gives the engineer a head start before the parcel arrives. The assessment that decides things is the bench one, completed 2 working days after the drive reaches us.
Read it as a first opinion from somebody who has seen those symptoms a few thousand times over. Each one maps to its common cause, what needs doing right away, and an honest timescale. The bench work then identifies the exact fault and fixes your price.
No. First of all, an engineer calls you back and you talk it through. If you would rather skip the conversation, just wrap the device up and send it directly to our Cambridge location.
// getting your device to us

Getting it here — no great performance

Most items arrive at this bench by insured and tracked post. We recommend getting a quote first, either by telephone or using our free online diagnostic, and once you have received your quote, simply post the item. Post is the steadiest way to move a poorly drive, and a parcel sent from Norfolk typically arrives on the bench within a working day.

Is the drive still bolted inside a laptop, desktop, MacBook, iMac, server or CCTV / DVR recorder? Before sending, remove the hard disk drive (HDD) or solid state drive (SSD), as we do not accept whole units. From a DVR or recorder, send just the disk. From a server or RAID, take out the disks and clearly label each disk by bay number. A network attached storage (NAS) device may be sent as its disks if they can be removed; otherwise please send the NAS itself. There is only one type of drive we are unable to accept: storage soldered onto a motherboard (e.g. Apple Silicon Macs, extremely thin laptops). In such cases, if the storage cannot be taken out it cannot be accepted. If you are unsure whether you have a removable drive or not, call us before sending anything.

  • Wrap the drive in bubble wrap, pack it into a sturdy box or padded envelope and make sure there is no movement in transit. Do not include any cables, caddies etc., except when sending a single external hard drive, which should come whole with its power supply and its own cable.
  • Print out the shipping & booking-in form (PDF), add your name, phone number and a few sentences explaining what happened, and send that with the drive.
  • You can use Royal Mail's Special Delivery service, which tracks and insures your package door to door. Alternatively you could find a courier of your own to do the same thing.
  • Handing it over personally? Once you have received your price quote, our reception will take your drop-off, Monday to Friday, 9am to 5:30pm. No need to book an appointment.

Otherwise you can post it using a tracked service and we will receive it the following working day. We will contact you as soon as we have your drive and it is booked onto our bench.

If you're unsure of what to include in the box, please call us on 0800 689 0668 before sealing it. Or, for a first view on what we can do, you can use our 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.
