## 项目历史与用法
dc3dd is a forensic-acquisition-oriented patch of GNU dd. Its official SourceForge description emphasizes on-the-fly hashing, split output files, pattern writing, a progress meter, and file verification, all aimed at evidence imaging workflows rather than general file copying.
### 项目历史
The project tracks GNU coreutils ancestry through dd while carrying forensic changes in its own SourceForge code tree and release archives. The 7.3.1 archive ChangeLog records a long run of imaging-specific work from 2008 and 2009, followed by later maintenance releases in 2014, 2016, 2023, and the current 7.3.1 release.
### 采用历史
dc3dd became a package-manager-visible member of the small family of forensic dd variants. Its official file feed notes Unix-like support for the current base version and a separate Windows/Cygwin line, while the input package facts show distribution through Homebrew, Debian, Fedora, MacPorts, Nix, Ubuntu, and openSUSE.
### 使用方式
Package users reach for dc3dd when they want dd-style acquisition with integrated hashes, verification, progress reporting, and output splitting. Those features reduce the shell glue otherwise needed around GNU dd in forensic imaging runs.
### 为什么软件包爱好者会关心
dc3dd matters because it is not a new imaging model; it is a conservative fork of a classic Unix primitive with forensic defaults bolted close to the copy loop. That makes it attractive to packagers and incident-response toolboxes that value scriptability and familiar dd semantics.
### 时间线
- 2008: ChangeLog entries record imaging-focused features such as dynamic error recovery, split input verification, Cygwin support, and progress improvements.
- 2009: ChangeLog entries record threaded hashing/I/O, HPA/DCO detection, multiple simultaneous outputs, and hash-based verification.
- 2014: SourceForge file feed lists dc3dd 7.2.641 artifacts.
- 2016: SourceForge file feed lists Windows/Cygwin artifacts for dc3dd 7.2.646.
- 2023: SourceForge file feed lists dc3dd 7.3.1.
### Related projects
- GNU dd remains the base utility lineage; dcfldd is a closely related forensic dd variant with similar package-manager audiences.
