Data Recovery Tool

Data loss events require informed decisions. This tool provides a structured assessment by analyzing storage metadata and filesystem structures to estimate recoverable data and outline salvage potential. It targets individuals, IT technicians, and consultants needing a pre-recovery plan before committing to actions. It emphasizes safety and measurable outcomes rather than guesswork.
Core capabilities include a read-only scan engine, filesystem-aware metadata analysis, a recoverability score, and a prioritized action list. Required features: read-only scan, metadata interpretation, quick/deep scan options, and a downloadable report. Optional features: file-type filtering, selective recovery, batch export (CSV/JSON), offline analysis, and multi-drive analysis.
Inputs include drive_type, volume_size, file_systems (NTFS, FAT32, exFAT, ext4, APFS, HFS+), scan_depth, and optional file_types. Outputs include recovered_file_count, estimated_recoverable_percent, risk_score, and recommended_actions, plus export formats.
The tool uses a multi-pass approach: metadata examination (allocation tables, directory structures), lightweight carving checks, and a probabilistic recoverability score. Recoverability is modeled as Recoverability = min(1, (Coverage * MetadataQuality * Readability) / 100). It provides caveats about data integrity and variability across environments.
It handles invalid inputs, encrypted volumes, and inaccessible media with conservative estimates and clear outputs, avoiding guarantees. Privacy considerations apply to deployment modality (local vs cloud) and data handling.
