The owner of this SD card had already done some investigating. The card had "become unresponsive" across several devices, and — the case taken apart for a look — revealed "a small crack in the item" that "doesn't appear to go all the way through". That last observation is the entire case, stated in one line. A crack that severs a connection while sparing the memory silicon is an inconvenience: the chip is read directly, past the broken pathway. A crack that runs through the storage silicon itself is the one limit in flash recovery that no equipment argues with. Depth is everything with a cracked card — and depth is measured under magnification at a bench, not guessed from a kitchen table. The hopeful sign: cards usually crack at their edges and connections first, and 'doesn't appear to go all the way through' is, more often than not, the right guess.
| Media | An SD card, unresponsive on several devices — case opened by the owner, a small crack visible, apparently not running full depth. |
| Reported situation | SD card · unresponsive across devices · case taken apart · small crack found · looks partial, not through-and-through · photos wanted. |
| Fault class | A partial fracture in the card's board or package — most likely severing traces while sparing the memory itself, given the apparent depth. Reached by chip-level reading past the break; a crack through the storage silicon is the one true limit, settled by inspection. |
| Equipment used | Stereo microscope survey — the crack mapped across board, traces and package, its depth assessed; the memory read at chip level past the severed pathway, lifted under hot air where the break demands it, onto a specialist programmer; the controller's arrangement reconstructed; photos carved by content in PhotoRec, opened to verify, delivered on fresh media. |
A modern SD card is mostly packaging around two working parts: a controller and the memory silicon. Cracks overwhelmingly begin where the mechanical stress does — at edges, corners and the contact end — and their first casualties are the fine copper traces running between components. A severed trace disconnects the machinery without touching the stored charge, which is why 'cracked' and 'lost' are different words in this trade. The card stops answering because a wire inside it is cut, not because the photographs went anywhere.
The owner's observation — not all the way through — gets tested rather than trusted, because the stakes are asymmetric. Under the stereo microscope the crack is followed across the package: where it runs, what it crosses, and above all whether it enters the memory silicon itself. Silicon that has fractured through the storage array is beyond every lab on earth; that's said plainly here because honest limits are part of the service. But the odds favour this owner: partial cracks that leave a card merely unresponsive usually turn out to be trace-deep, exactly as the kitchen-table inspection suggested.
Past the inspection, the recovery runs on the chip-level playbook. The memory is read directly — in place where enough connection survives, or lifted under hot air and read on the programmer where it doesn't. The controller's scrambled arrangement of the data is reconstructed, and the photographs are carved out by content and opened one by one. The crack keeps its victory over the card. The pictures leave anyway.
The crack mapped end to end under the stereo microscope before anything else — depth, path, casualties. With the memory silicon confirmed clear, the chip is read past the break: lifted under hot air onto the programmer where the severed traces demand it. The raw read is descrambled to reconstruct the card's logical contents, PhotoRec carves the photos by content, and each is opened to prove it whole before delivery on fresh media.
Settled the only way it can be — by looking properly. The inspection and diagnostic are free, reported within two working days of the card arriving, and the verdict comes with one fixed written figure and an honest account of what the crack did and didn't reach. Chip-level work is physical, so half is payable up front, the balance only on proven recovery. If the silicon itself proves fractured, you'll be told that straight, and no recovery fee arises on work that can't succeed.
Stop flexing it — including the small unconscious flex of pushing it into one more reader to check. A partial crack propagates under load, and the distance between 'traces cut' and 'silicon gone' can be one firm press of a card slot's spring. Since the case is already open, that's no harm done — just don't dismantle further, and don't let anyone near it with glue or a soldering iron. Sandwich it in something rigid, pad it, post it. The crack's depth is the whole question, and it deserves a microscope's answer, not a guess.
