It Is Talking to the Computer, So the Crack Did Not Sever Anything
His enquiry describes physical damage and, without realising it, evidence that it was survivable. A 128GB card that "cracked or snapped when putting it into a device. The card is still intact, but has a hairline crack in it. When putting it into a computer, it ask"s to be formatted. A card that asks to be formatted has introduced itself successfully — which means the internal connections between memory and contacts are still carrying signals, and the crack has already been ruled out as the obstacle.

The decode: what the format prompt proves about the crack
Why the prompt is good news: for a computer to offer to format a card, it must first have detected it, powered it, and had it announce itself and report a capacity. All of that requires the internal connections between the memory package and the external contacts to be carrying signals — which is precisely what a crack in the wrong place destroys.
So the question that usually dominates cracked-card cases is already answered. On a small card, memory and controller are moulded into a single block with fine routing running to the contacts at the front edge, and a fracture crossing that routing means the card cannot present itself at all. His does present. The crack ran through material carrying nothing essential.
What the fault actually is, then: ordinary filesystem damage. The card can be addressed and its filing structures cannot be interpreted, which is among the most recoverable conditions in this archive and has nothing to do with the crack. The two events may not even be related — a card damaged during insertion may also have had its structures disturbed by the same interrupted moment.
Why the format must stay refused: it writes a fresh empty index over exactly the region a reconstruction reads, and it will be offered on every connection. Accepting it would convert a straightforward case into a carving job, and on a card that has already survived physical damage that would be an unnecessary loss.
Why he must stop inserting it, despite it working: this is the part in tension with the good news. A cracked card is flexed by the contacts as it seats, and a fracture that is currently survivable can propagate under that load. Each insertion is a chance to turn a working card into one that no longer presents — and the card is currently in the best state it will ever be in.
Why capture takes priority over everything: the position is unusually good and unusually fragile at the same time. The card answers today. Imaging it once, now, converts a fragile physical situation into a stable copy, after which the structures can be rebuilt at leisure against something that cannot crack.
The general note: a card that cracks during insertion usually cracked because it was forced or inserted at an angle. Worth checking the slot as well as the card.
On the bench
No further insertion attempts were made, contacts flexing a cracked card as it seats and a survivable fracture propagating under that load. Enumeration was confirmed as evidence of surviving internal routing — a card reporting capacity requiring the fine connections between memory package and contacts to be intact, which places the fracture in material carrying nothing essential. The card was imaged write-blocked under strict timeouts behind the DeepSpar USB Stabilizer 10Gb, and structures reconstructed on the image from their surviving copies.
The outcome
Enumeration accepted as proof the routing survived, the card imaged once under strict timeouts and the structures rebuilt from the copy. Free assessment, one fixed written figure including VAT, 50% of parts and labour upfront with the balance only on successful recovery. The decode: your format prompt is evidence in your favour. A computer offering to format a card has already detected it and had it report a capacity — which needs the fine internal connections intact. The crack missed them. What remains is ordinary structure damage, and the card is at its best right now.
Cracked card that still gets recognised
Refuse the format, then stop putting it in anything. That prompt is genuinely encouraging: for a computer to offer to format a card it must first have detected it and had it report a capacity, which requires the fine internal connections between the memory and the contacts to be carrying signals — exactly what a badly placed crack destroys. So yours ran through material carrying nothing essential, and the fault behind it is ordinary filesystem damage. But the contacts flex a cracked card as it seats, so every insertion risks propagating a fracture that is currently survivable. Your card is in the best condition it will ever be in, which makes capturing it now the priority.
