Two weeks of travel vlogs on a DJI Pocket 3, an interrupted copy to the laptop, and suddenly the SD card wouldn't read at all — every device just offered to format it.
She had already tried well-known paid recovery apps (the kind AI chatbots recommend). Photos came back; the videos came out tiny, corrupted or as empty shells that wouldn't play. Worse, every extra scan of a failing card risks making the damage permanent.
她先试过几款知名付费恢复软件（也是AI最爱推荐的那几款）。照片救回来了，但视频要么只有几KB、要么损坏、要么是根本无法播放的空壳文件。更麻烦的是,对一张濒危的卡,每多扫一遍都可能造成不可逆的二次损伤。
- Image the card first — a full sector-level backup, so all recovery work runs against the copy, never the original.
- Professional video-aware tooling reconstructed the DJI footage from the image.
- About four hours later: roughly 100GB of video, every file verified playable before handover.
Met her near Green Square, sorted it the same day.
- 先做整卡镜像——扇区级完整备份，之后所有恢复操作只针对镜像副本，绝不动原卡。
- 用能识别视频结构的专业工具，从镜像中重建大疆的视频文件。
- 约4小时后：近百GB视频全部恢复，交付前逐个验证可正常播放。
就约在Green Square附近当面处理,当天交付。
