1.83 GB Free of 1.83 GB

Beginning in approximately 2010, one camera used a single 2GB card to save perhaps a thousand images, and until yesterday "it was completely fine". The first shock came when a brand-new card reader and a phone were used: "The pictures have completely disappeared". Back in the camera, the card is "also saying no pictures". However, the same card, when inserted into a laptop, reports "1.83 GB is free of 1.83 GB". This last number is your diagnosis: the card is reporting exactly how large it actually is (the geometry), while lying to you about what is stored on it (your photographs). A lost file system, not lost photographs, is what this card's behaviour points to.

// case at a glance
Media2GB SD card from the FAT16 era, used continuously but lightly in a single camera for some fifteen years, now reporting as a healthy, empty volume everywhere
Reported situationApproximately a thousand photographs taken since 2010 · card worked normally in the camera the day before · first attached to a phone via a new USB-C reader, no pictures shown · camera now also says there are no pictures · computer shows full capacity free · another card works properly in the same reader
Fault classData loss at filesystem level: the volume structures appear blank while the geometry reads correctly, consistent with a host device re-initialising the card or damage to the allocation table, with most of the data area remaining intact
Equipment usedThe card was first imaged under a hardware write-blocker at full physical capacity before any interpretation. Both copies of the FAT were extracted from the image and compared. The data area was signature-carved in PhotoRec and R-Studio for JPEG and camera-native formats. PC-3000 Flash was on standby in case enumeration degraded. Each recovered image was validated by rendering it.

The decode

Identical amounts of free and total space are a major clue. Most failing cards struggle to report anything. Your card, however, has provided every detail, including its exact geometry, and shows every byte of its memory as empty. Obviously the controller and memory of the card work properly. The area that keeps track of where each photo is located on the card (the index) is what is missing, not the library of photos themselves.

The newest addition explains why this happened so suddenly. This card worked perfectly in the camera, met a phone by way of a brand-new card reader, and showed nothing anywhere after that. Smartphones frequently offer to format a card if they cannot immediately read it, and one tap on an unfamiliar dialog box confirming this action quick-formats the card. The other likely cause on a card this old is corruption of the allocation tables. Either cause produces this very same symptom, and the bench treatment is the same too.

Almost all of your photographs remain intact after a quick format, since the new blank directory structure written at the start of the memory card uses minimal space and leaves your actual photograph files untouched. On a 2GB FAT16 card that filing region is tiny, so there is a high probability of restoring those photographs.

What affects how well you recover from this situation is whether any new data has been written to the card. If you add pictures, documents and so on to an empty-looking memory card, the new additions will overwrite the old data on it. In this case the card was simply investigated: it was not reused, and nothing was written to it. It was the lack of writing, more than anything else, which determined the outcome.

Even when all of your images can be recovered, their original names and folder structure may not be. The image recovery process identifies each image by its own signature and therefore does not require the original directory listing (index). Camera manufacturers typically assign generic file names to their images anyway, so once the images are recovered, the most likely thing you will miss is the date on each folder. Each of your photographs contains its own date and time stamp.

After 15 years of continuous use, the card has earned its retirement once the data is recovered. While it was completely blameless in this case, consumer-grade flash memory from 2010 no longer owes anyone anything. Recover the data, verify it, and then let the card rest while it is ahead.

On the bench

The card was imaged at its full physical capacity under a hardware write-blocker before anything interpreted it. Both copies of the allocation table were extracted from the image and compared, confirming freshly initialised structures over an untouched data area. The data area was then signature-carved in PhotoRec and R-Studio for JPEG and the camera's native formats, with PC-3000 Flash ready in case enumeration failed, and the recovered photographs were validated by rendering.

// the outcome

The outcome

Write-blocked imaging, a comparison of the allocation tables, carving of the data area and validation of the photograph set. Free assessment, one fixed written price, plus VAT; for deleted, formatted or corrupt data you only pay if we recover your data. The decode: the card reports itself as empty, not damaged. The index went away and the photographs remained. Since nothing was written on top afterwards, the years are still there for us to collect.

A card that suddenly shows empty everywhere

Stop using it right away. Most importantly, don't take any more photos with it and decline every prompt to format. "Full capacity free" on a card you know was full is a filesystem statement; it doesn't mean the storage area where your data sits is empty. Take note of the last device that touched the card, because an unfamiliar phone or reader prompting you to fix or format a card is the classic route to exactly this. Recovery prospects depend on the next write, so the best move is to make sure nothing else writes to it.

Sending this in from Sheffield? All cases begin with a free diagnostic, followed by one fixed written quote for our services prior to commencement of work, and in most cases you only pay if we recover your data. To get a quote first, call us on 0800 689 0668 or use the free online diagnostic. If your data is stored inside a laptop, PC, Mac or server, simply remove the hard drive or SSD and post us just the drive. We don't offer a service to remove drives from inside computers, and we don't recover storage soldered onto a motherboard (e.g. Apple Silicon Macs); if you're not sure which kind you have, ring us first. For servers, RAID and SAN, take the disks out individually and label each disk with its bay. For a NAS, take the disks out if you can; otherwise, you may send the entire unit. A single external drive goes whole, in its enclosure, with its cable and power supply. Post it tracked and insured to our Leeds Data Recovery lab, or drop it off at the lab's reception in Leeds, Monday to Friday, 9am to 5:30pm, no appointment needed. Full sending instructions and the shipping form are here.
