Broken SD card: when only a laboratory can help
Can data be recovered from a physically broken SD card?
Short answer
Only a laboratory can help: software cannot scan blocks the operating system never reads, and a cracked, bent, burnt or contactless card will not deliver them. Unplug it now, because every power cycle can worsen a damaged controller. Do not force it into other readers; send it to a qualified flash recovery laboratory instead.
The situation
The card is cracked, bent, burnt, missing contacts, or never enumerates with the correct capacity.
Recovery software works on data the operating system hands it. A cracked, bent or burnt card, or one with damaged contacts, never gets that far, so no program on your computer can reach the flash inside. This case belongs to a laboratory from the first minute.
01 / Diagnose
Work out what actually disappeared
In an SD card the memory chip and the controller sit under one plastic shell. Physical force breaks tracks, heat damages the controller, and a card that enumerates with a wrong capacity or not at all is reporting that this path is broken. Laboratories reach the flash directly and read it with their own equipment.
Software cannot scan blocks the operating system cannot read, and power-cycling a damaged controller can worsen the fault.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Unplug the card now and leave it unpowered, because each power cycle can push a damaged controller further towards a total failure.
- 2
Store it dry and static-safe in an envelope or antistatic bag, and keep the fragments together if the shell broke apart.
- 3
Write down what happened, what the card contained and how valuable it is, so a laboratory can quote realistically.
- 4
Choose a flash recovery laboratory with chip-off experience, ask for a written diagnosis and a fixed price before anyone opens the card.
Do not push the card into one reader after another, do not warm it, freeze it, bend it back or clean the contacts with solvents, and do not open the shell. Each of those can destroy the connection between the memory chip and the pads a laboratory needs.
03 / Choose the method
Match the tool to the source
For stable, readable exFAT, NTFS and FAT16/FAT32 or uncompressed IMG, DD, RAW and BIN images.
Unconfirmed exports are marked .UNVERIFIED.
This is outside what any desktop program can do, File Recovery Hero included: it reads exFAT, NTFS and FAT16/FAT32 media the system delivers, and a physically broken card delivers nothing. Laboratory work costs considerably more than software and cannot promise a result.
04 / Verify
Check the recovered content, not just its name
Judge the laboratory before you judge the result: a serious one diagnoses first, names a price in writing and works on a no-data-no-fee basis. When files come back, open a sample across the whole card and check that sizes and playback lengths match what was recorded.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can physically damaged SD or microSD card be recovered in this situation?+
Recovery software works on data the operating system hands it. A cracked, bent or burnt card, or one with damaged contacts, never gets that far, so no program on your computer can reach the flash inside. This case belongs to a laboratory from the first minute. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not push the card into one reader after another, do not warm it, freeze it, bend it back or clean the contacts with solvents, and do not open the shell.
Does scanning write to my memory card?+
Your memory card is only read. Nothing is saved to it.
How do I know whether the result is complete?+
Judge the laboratory before you judge the result: a serious one diagnoses first, names a price in writing and works on a no-data-no-fee basis.
