Technical Architecture & Engines

Engineered for True Recovery Precision

DiskWarren Recover pairs deep filesystem metadata reconstruction with raw sector signature carving. Discover how our dual-engine architecture rescues lost files across internal and external media.

Filesystem-Aware Quick Scan Engine

NTFS • FAT12/16/32 • exFAT

When files are deleted, Windows doesn't erase the data sectors immediately. Instead, it marks directory records or cluster allocation tables as unallocated. Our filesystem engine reads these structures directly from disk without OS interference.

NTFS Master File Table (MFT)

Parses $MFT records, extracting $FILE_NAME, resident data streams, non-resident cluster runs, and orphan parent folder linkages.

exFAT Directory Traversal

Traverses exFAT File and Stream Extension entries. Follows contiguous allocation flags to immediately recover unfragmented camera files without cluster walk latency.

FAT12/16/32 Cluster Chains

Decodes 8.3 and Long File Name (LFN) directory entries. Traces cluster chains through the File Allocation Table while testing for cluster reuse by active files.

Deep Signature Carving Engine

Raw Sector Scanning • 20+ Validated Signatures

When a partition has been formatted or the filesystem directory tables are severely corrupted, our carving engine scans raw sectors sequentially, matching magic byte headers, footers, and internal container structures.

Photos & RAW

JPEG, PNG, GIF, TIFF, BMP, WebP, and camera RAW (Canon CR2/CR3, Nikon NEF, Sony ARW).

Documents & PDF

Microsoft Office (DOCX, XLSX, PPTX), Adobe PDF, RTF, and plain text UTF-8/UTF-16.

Video & Audio

MP4, MOV, MKV, AVI, MP3, WAV, FLAC, and AAC container structures.

Archives & Data

ZIP, 7Z, RAR, TAR, GZ, and SQLite database file headers.

Raw Byte-for-Byte Disk Imaging

Forensic .RAW / .DD Disk Cloning

Designed specifically for drives with degrading physical media. Instead of stressing unstable read heads with repetitive random seeks during deep scans, DiskWarren clones the drive into an exact raw image in a single pass.

Bad-Sector Skipping

Skips unreadable blocks after configurable timeouts, maintaining imaging forward progress.

Virtual Image Scanning

Mount and scan .raw / .dd files identically to physical media without keeping the failing drive connected.

Sector Defect Map

Records a forensic bad-sector map, highlighting which file clusters were affected by physical damage.
