Filesystem Support
Partition Analysis
- FAT12/FAT16/FAT32 cluster recovery and allocation table reconstruction
- NTFS MFT parsing with attribute extraction and fragmentation handling
- ext3/ext4 journal recovery and inode reconstruction from deleted entries
- RAID volume detection (RAID 0/1/5/6) and member reconstruction
Intelligent Pattern Recognition
- Magic byte signatures — header/footer carving for common file types
- Shannon entropy analysis (0.0-8.0 scale) for data classification
- File boundary detection algorithms for fragmented recovery
- File size heuristics and clustering for accurate reassembly
