Abstract—Data recovery software for mobile phones is engineered to retrieve lost, deleted, or corrupted images from internal storage, SD cards, and cloud backups. These tools utilize advanced scanning algorithms, deep file search, and AI-based reconstruction techniques to restore photos in formats such as JPEG, PNG, HEIF, and RAW. The success of data recovery is influenced by factors including file overwriting, storage fragmentation, and the extent of data corruption. To maximize recovery chances, users are advised to cease device usage immediately after accidental deletion and avoid saving new files, while regular backups and cloud synchronization remain the most effective preventative strategies against permanent data loss.
This research paper presents a comparative analysis of three prominent forensic data recovery tools—FTK Imager, Test Disk, and Foremost—evaluating their effectiveness in retrieving lost files from various storage media. FTK Imager, a proprietary tool, is recognized for its structured imaging and high recovery success rates, supporting multiple file systems and forensic image formats. Test Disk, an open-source solution, excels in partition recovery and repairing non-bootable disks, though its undelete
feature is limited to specific file systems. Foremost, a
command-line tool, specializes in file carving, making it
effective for recovering deleted files even when file system metadata is compromised, but it may struggle with
complete file restoration in cases of fragmentation
