SD card suddenly asking to be formatted? Behind the scenes in our data recovery lab with a SanDisk card full of car racing footage.
This is a real case we worked on. A SanDisk 32GB SD card started demanding a format. An earlier attempt elsewhere had copied some files to a USB stick, but none of the videos would play.
How our data recovery engineer approached it:
1. He set the USB stick of broken clips aside and went back to the card itself.
2. He cloned the card sector by sector on the Atola Insight Forensic. It imaged cleanly to 100% with no read errors, so the chip was healthy and the damage was logical, in the file system.
3. Several standard recovery programs saved files with the right sizes and dates, but none of the videos would play. The footage used a high bit-rate codec that most tools were rebuilding just wrong enough to break playback.
4. Remembering an older job with a similar codec, he tried Disk Drill, a program he rarely needs. This time every clip played.
5. The corruption had stripped the file names and dates, so an AI assistant read the metadata inside each video and renamed everything back to its original name and timestamp.
All 21 clips, 22GB of footage, came back playable with their original names and dates. Start to finish, the job took about three hours.
A tip from the case: if a card asks to be formatted, do not format it and do not keep running recovery software on it. Those attempts can overwrite the structures a proper recovery needs.
