Memory card recovery in Plymouth. There is no second copy, and you cannot take the same photos again.

A memory card chooses its moment: halfway through a fortnight's holiday, or halfway through a backup meant to protect your work. Memory cards come to us from all over, including Plymouth, Cornwall and the Isles of Scilly. Most cards reading empty, locked or blank will still give up their photos. The one condition is that nobody has formatted the card first.

Nothing readable? Most jobs carry no bill Free diagnosis, then one written price Boxes come to the lab from Truro, Newquay and Tavistock

Shipping to us: once you receive your quote, pack it securely so it won't move in transit, get it insured for what it is worth, and send it by tracked post to our intake lab in Bristol. We pay the postage back to you. Please contact us before sending if you would like an engineer to check the packing before the box is sealed. More detailed instructions on sending your item to us can be found on our contact page.

What happens to a card while it is here.

Cases in the log →
01

A number on arrival, then the free diagnosis Free

Whatever is delivered is booked in using a unique reference (case number) on the date it arrives at the bench. The engineer will identify the actual fault at no charge. This gives a straightforward answer on what can be recovered from the drive and what cannot, plus one written quotation. There will be no further activity until you have read and accepted the quotation.

Diagnosis at no chargeA single written figureYou owe nothing yet
02

The card itself is left alone

An exact clone is made first. The original card then goes back in its case, and all the work from there on is done on the clone.

03

Rebuild the tables, or carve the frames

The clone is where things get repaired. If the file tables can be rebuilt, the folder names come back attached to them. If not, pictures are recovered from their header bytes alone, and RAW files are no more trouble than JPEGs.

Nothing leaves unexamined

Counting the pictures found says nothing. Each recovered image is opened one at a time and must open completely, at the full dimensions the camera wrote it.

You give the word, and it ships back

Give yourself time to consider it. It costs you nothing. We list all of the files we recover for you before sending out an invoice, and we only ask for payment once you have authorised it. We also buy media specifically for your recovery and send it back to you, with the return postage paid by us. The case stays here on our bench until we have your confirmation that the files open properly on your own machine.

The faults we see most

  • Fake cards are the only game nobody wins: the card controller has been reflashed to show far more capacity than the flash really has. Once data is written beyond the true capacity, the file is taken and lost. Nothing was ever stored, so nothing can be restored.
  • Unsure about a card? Fill it up and read the entire card back. Under Windows use H2testw to do that; on Mac or Linux use F3. The fake figure is written directly into the card's registers. That is why the packaging states it, the printing states it, and Windows states it.
  • Cards today are made as one single block, with the controller and the flash memory set in the same resin. When the card fails to respond, it is read through small contact pads on the die under a microscope. No card reader is used.
  • Formatting doesn't fix anything: the camera writes new tables over what holds your folder names, the frame order and the dates.

The number nobody knows: there is no reliable count of how many counterfeit cards are in circulation. Labs and manufacturers agree it is a wide problem, fakes appear here often enough, and every percentage in published reports began as an estimate. The actual number wouldn't change the rule anyway: the moment data is written beyond a fake card's real capacity, it is beyond the reach of any lab.

Photos taken at a night-time wedding, and an empty card the next morning

Nothing was done to the card itself. The card was cloned first, and every step after that happened on the clone: the file system was restored, and a deep carve went after the images that no longer had a place in it. A 512GB SanDisk, filled the previous evening and empty by morning, gave up every image. The photographer kept the client.

Every frame recovered48 hours on the bench

Before you seal the box.

Get these done

  • Take the card out once and leave it be
  • Get a quote, then send it in a rigid case or taped to thick cardboard
  • Tell us the camera and what it was recording
  • Give the error message word for word

What to avoid

  • Allowing the camera to format it and hoping
  • Carrying on shooting after something went wrong
  • Aiming free utilities at the original card
  • Working through every reader in the drawer

Questions that come up most weeks.

The camera wants to format the card. Should I?

No. Formatting writes new file tables over the exact records holding your file and folder names. Leave it as it is and a lot more of it can be recovered, names included.

Are they just JPEGs, or do RAW files come back as well?

RAW files too. Carving works on signatures found at the start of a file, and RAF, DNG, ARW, NEF and CR3 all carry one. Video containers behave the same way. Much of what we receive comes from people who make a living taking photos.

The card broke in two. Are the pictures gone?

Often not. On a monolith card everything sits on a single die, so if the break went past that die, a chip-level read can still be done. Either way, the card itself is finished.

How quickly does a card come back?

Memory cards move through here faster than anything else. Most cards are back within two or three working days, sooner if time is pressing. Give us the date you need them and we will build the schedule backwards from it.

A drive that stays switched off gets no worse.

Diagnosis costs nothing. We give you a report listing which files can be read, which cannot, and what is needed to get them off. Do not connect the drive until then.
