SD and memory card recovery for Reading. There is no second copy, and that day will not happen twice.

A card is a £250 + VAT job, and the first look costs nothing. If a card appears blank, will not unlock, or has just gone dark, the pictures will nearly always be recoverable, unless someone has reformatted it in the meantime. No other device fails as regularly, and cards have an uncanny knack for choosing when to die: day four of a fortnight away, or the exact moment you were copying them somewhere safer. Around Reading they come from the freelance camera and edit crews working near the Shinfield studios, from photographers covering the fixtures at Newbury racecourse, from a Hungerford antiques dealer whose listings depend on the photographs, and from people returning home after holidays.

Memory card symptoms, and how urgent each is.

Packing and posting: first, get a quote by phone or with the quote form online (we will walk you through the steps). Second, pack it so it cannot shift around inside the box. Third, put a value on the parcel that reflects the data, not the price of the hardware. Then post it tracked and insured to the Oxford intake lab, or drop it off there yourself, Monday to Friday, 9am to 5:30pm, without an appointment. We cover the return postage. If you would like to talk to one of our engineers before you seal the box, please call. Everything is set out on the packing and postage page.

Which brands come in, and what fails on them.

SanDiskUltra, Extreme and Extreme Pro: in many photographers' camera bags, and faked more than any other range.
Integral & KingstonIntegral's SD and microSD, and Kingston's Canvas React Plus and Canvas Select Plus.
Sony · Lexar · ProGradeCFexpress cards in Type A and Type B, Sony’s TOUGH SD line, and the Gold and Professional ranges.
XQD & CFexpressFast, sealed units from Angelbird, Nikon and Sony: when one of these goes silent, the only way back into it is the bench.

01

Logged the day it lands, and the look costs nothing Free

A case number is assigned to your device when we receive it. An engineer then finds the real fault (free) before anything else occurs; you will be advised clearly of what will be returned and what will not, along with a single written price. Charges cannot begin until you have read this and accepted.

The look costs you nothingA fixed price, in writingStill nothing to pay
02

Nothing is written to the card

Nothing is ever attempted on your card. An exact byte-for-byte clone of it is made first; the original then goes into a protective sleeve and stays there, and everything else is done against the copy.

03

File tables rebuilt, or frames carved out

The repair is performed against the image. Rebuild the file tables and your folder names travel back with your photos. Where very little of the index survives, each file is identified instead by the first bytes it opens with and extracted individually. RAW files are treated the same as JPEG files at that stage.

Nothing goes back unopened

Counting files tells you nothing worth knowing. Every recovered image is opened one by one, and each has to render fully at the size the camera recorded it.

The list first, then the bill, then the files

You look at the file list first and make a decision about what to do. We will never invoice anything until you have said yes, and in most cases you only pay if we recover your data. All of the information that we recover will be put on new media purchased by us specifically for this job, and our company pays the cost of postage back to you. The case stays open on the bench until you tell us the files open on your own machine.

What goes wrong most often

  • A counterfeit card is the one fault no laboratory can fix: its controller has been rewritten to show more space than actually exists. Anything written past the reported size is acknowledged and then silently discarded. It never reached the chip, so there is no method to retrieve it.
  • Think a card might be fake? Fill the whole thing, then check each byte on the way back. H2testw will do the check on Windows; F3 is used for Mac and Linux. Checking the label achieves nothing: the box, the printed size and the size your OS reports all come from the same registers the card reports from, where the false figure is written.
  • Modern cards are moulded together in one piece: controller and flash set into one slab of resin. When one dies, all work shifts to the tiny contact pads on the flash die. A card reader is never used.
  • Formatting doesn't help anything: the camera simply writes new tables over the records holding your folder names, the frame order and the dates of capture.

A figure nobody actually holds: there is no dependable number for how many fake cards are circulating. Manufacturers and labs agree that the issue is widespread, we see plenty of them, and every percentage that appears in print began as someone’s estimate. The exact number doesn't matter anyway: once data exceeds the genuine capacity of a counterfeit card, it is not sitting somewhere waiting for a lab to discover.

How one of these actually went.

An evening wedding, and a card empty by morning

Every frame came back from a 512GB SanDisk that had shown as empty at breakfast. No attempts were made on the card itself: a copy of it was made and all the work done there. First the file system was put back into order; then a deep carve went after the images that no longer had an entry pointing to them. The photographer kept the client.

What helps, and what makes it worse.

First things to do

  • Take the card out once, then never touch it again
  • Get a quote first, then place the card in a hard protective case (or tape it flat to stiff card) and post it
  • State the camera model it was taken from, and what is recorded on the card
  • Give an exact copy of the error message as it is displayed

What makes it worse

  • Letting your camera format the memory card and simply hoping for the best
  • Carrying on taking photos or filming once the camera shows a malfunction
  • Pointing free utilities at the original card
  • Trying every reader in the drawer in turn

Answers before you commit to anything.

The camera is asking to format the card. Should I?

Don't. The format creates an entirely new index right on top of the entries holding your folder names, your file names and your dates, so all you're left with is a numbered heap. Leave the card alone, and much more of the original structure will come back to you along with the images.

Do RAW files come back, or only JPEGs?

Yes, RAW too. Carving keys on the signature bytes at the start of a file. RAF, DNG, ARW, NEF and CR3 each open with such a marker, and the video wrappers are built on the same principle. Much of the work on this bench comes from photographers and filmmakers who do it for a living.

The card snapped in half. Have I lost the pictures?

Often not. Everything on a modern card resides on a single die, so what's important is whether the crack goes across that die. Miss it and the pads can still be accessed directly. Either way the card has to be scrapped; the pictures are the point.

How soon does a card come back?

Cards move faster than anything else here: we usually get them back within 2–3 working days, much sooner when there is a deadline. Simply tell us the date you need them by, and we will schedule the work backwards from that.

Nothing gets worse while it sits switched off.

There is no charge for the look. You then receive a list of the files that opened, those that did not, and a fixed amount to complete the job. Keep it switched off until you have received that in writing.
