One Machine Said Corrupt. The Other Showed the Pictures.
Her 8GB card was not full
, and it says is corrupted when put it in my laptop
. That would have been the whole story, except that she could still see the photos on my camera
. Before she rang she had worked through different devices and adapters
and arrived at the conclusion on her own: it's definitely the memory card
. She was right about that, and the camera had already told her the more useful half of it.

What failed, and why.
A card carries two quite separate things, and the two of them fail separately. One is a short set of records: a name, a length, and the place on the card where each file begins. The other is the pictures themselves, sitting where they were written and taking no notice at all of whether those records still make sense. A camera asks a card very little and reads it in the simplest way there is, which is why hers kept finding the photographs. A computer expects the whole structure to add up, and where it does not, the only word Windows has for it is corrupt — followed at once by an offer to put the card right. Accept that offer and a fresh empty structure goes straight over the records a rebuild would have used. A card or a stick falls in the published £250 + VAT band, and finding out which of the two faults you have costs nothing.
What the bench did with it.
The order of the job →| Equipment used | Its work on this job | The reason for it |
|---|---|---|
| PC-3000 Flash | Copied the card off in full, taking nothing on trust from its file system | Reads flash directly off the chips, going round the controller, with a maker-ID library kept current here |
| R-Studio Technician | Rebuilt the records that could still be rebuilt | Puts an array back together from the images, and reads nearly every file system |
| UFS Explorer Professional Recovery | Carved by signature wherever a record was past mending | Opens APFS, ReFS, XFS, ZFS and Btrfs when other software will not |
What the bench did with it.
Nothing starts until a copy exists
Give a card power and its controller sets about housekeeping of its own, with no interest whatever in blocks a recovery might want afterwards. So the copying came first. The card was read off in full behind a write-blocker on a controlled reader, and then it went back into its case. Everything from that point ran against the copy, which meant no later step could cost her a picture.
Use whatever the structure still gets right
Not all of the structure had gone. Where a record still described a file properly it was used, and the picture came back whole: its own filename, its own date, the full chain of blocks behind it. That hands back the photograph she took, rather than something assembled afterwards to resemble it. Records that no longer added up were set aside instead of trusted.
What was left had to speak for itself
Pictures beyond the reach of a record were made to identify themselves. JPEG and camera-raw signatures were picked out of the raw blocks, the data following each one was put back into order, and a filename went onto a picture only where the header, or a readable date within it, justified one.
What went home.
Most of the card returned with its original filenames intact. Whatever had to be carved came under names the bench generated, in a folder of its own, and those pictures were opened and looked at here first, because a listing proves nothing whatever about a photograph. One instruction travelled back with the new card: when a computer offers to repair a card the camera can still read, decline. The £250 + VAT figure for a card was agreed in writing before any chargeable step.

Prices are published and fixed. Memory cards and USB sticks are priced at £250 + VAT. A drive on its own comes to £300 + VAT. Anything holding a second disk, whether RAID, NAS or a server, opens at £500 + VAT. The first look costs nothing, and the figure that follows is fixed and in writing before a penny is charged. Switch it off and post it in. Most jobs carry no fee where no files return.
