Data Recovery of 108GB After SD Card Transfer Failure Caused Data Loss in Glen Rock, New Jersey
Data recovery became critical for a small business in Glen Rock, New Jersey, when a routine file transfer unexpectedly failed. The company was transferring important work data from a 128GB SanDisk Extreme Pro memory card to an external USB hard drive. Initially, several files were copied successfully. Then, without warning, the transfer process stopped.
After the interruption, the SD card became completely unreadable. The MacBook no longer detected it, and none of the files could be accessed. The card contained 108GB of essential business data, including documents and active project files. With operations at risk, the business contacted WeRecoverData, a trusted global leader in professional data recovery services.
Why the SanDisk Memory Card Became Unreadable
SanDisk Extreme Pro SD cards are widely used in professional environments, but even high-performance media can fail under certain conditions. In this case, the interrupted file transfer likely caused severe file system corruption or triggered a controller failure.
When a controller fails or the file system becomes corrupted, the stored data often remains physically intact within the NAND memory chips. However, the card can no longer reference file locations, making it appear empty or undetectable. Standard consumer recovery software typically cannot resolve controller-level failures or rebuild heavily corrupted file systems.
Chip-Off Recovery and File System Reconstruction
After the SD card arrived at the WeRecoverData lab, engineers performed a comprehensive diagnostic. Testing confirmed that the NAND memory remained healthy, but the onboard controller had failed during the transfer process.
To access the data, engineers used a chip-off data recovery method. They carefully removed the NAND memory chip from the SD card and connected it to specialized recovery hardware capable of reading raw memory data directly.
Once extracted, the raw data underwent detailed analysis. Using proprietary reconstruction tools, engineers rebuilt the corrupted file system, reassembled fragmented data clusters, and restored the original folder structure.
Each recovered file was thoroughly verified to ensure integrity, completeness, and usability.
Full 108GB Business Data Recovery Success
After meticulous reconstruction, WeRecoverData successfully recovered the entire 108GB of business data from the failed SanDisk Extreme Pro memory card. All documents, project files, and records were restored and organized exactly as needed.
The recovered data was delivered on a secure external drive, allowing the business to resume operations without disruption.
When an SD Card Fails, Recovery Is Still Possible
This Glen Rock, New Jersey case demonstrates that even when a memory card becomes unreadable during a file transfer, professional data recovery can still achieve complete results.
At WeRecoverData, advanced chip-level techniques and forensic reconstruction methods make recovery possible when standard software solutions fail. When your memory card stops working, expert intervention can ensure your files do not disappear with the device.
