SD Data Tool

The SD Data Tool analyzes SD cards connected to Windows 10 systems to assess health metrics and infer recoverable data. It supports quick scans for speed and deep scans for thoroughness, and it recognizes common file systems (FAT32, exFAT, NTFS) and partition layouts. This information helps users decide whether to proceed with preservation, replacement, or targeted recovery efforts, and it provides a repeatable baseline for ongoing media health monitoring.
Conceptually, the tool reads non-destructive blocks, detects file-system signatures, and records read errors, bad sectors, and fragmentation patterns. It uses a simple heuristic to compute a health score from error rate and wear indicators, and it estimates recoverable content based on free space and observed fragmentation. A structured report exports metrics, assumptions, and recommended actions in CSV or JSON.
Audience includes IT admins, photographers, archivists, and educators who manage removable media. It differentiates itself by fast, transparent estimates, non-destructive analysis, support for multiple output formats, and ready-to-share reports suitable for risk management, compliance, and continuity planning. It is designed to be deterministic and repeatable across devices, making it easier to triage media and schedule follow-up recovery efforts.
