## プロジェクトの歴史と使われ方

format-udf is a Bash script for formatting block devices as UDF volumes intended to be read and written across Windows, macOS, and Linux. Its README presents it as a compatibility tool for external hard drives and flash drives.

### プロジェクトの歴史

The GitHub repository was created in August 2014. The README says the project was created to address operating-system-specific quirks that make naively formatted UDF devices fail across platforms, including block-size expectations, partition-table behavior, and macOS full-disk mounting behavior.

### 採用の歴史

The project remains a focused utility rather than a broad platform. Its official release history shows incremental fixes around OS and device support, including macOS 10.12 support, loop devices, udftools 2.0+, NVMe, and broader block-device handling.

### 使われ方

Users run the script against a Linux device such as /dev/sdx or a macOS device such as /dev/diskN, supplying a volume label. The script detects block size, validates dependencies, can wipe the target, formats with UDF revision 2.01 for compatibility, and writes a fake MBR unless disabled.

### パッケージ好きにとっての重要性

format-udf matters to package nerds because it codifies a pile of cross-platform filesystem edge cases in one auditable shell script. It is the kind of small system package that exists because the underlying native tools are powerful but not friendly to a portable-disk workflow.

### タイムライン

- 2014: GitHub repository created.
- 2016: Release added macOS 10.12 support.
- 2018: Release added support for udftools 2.0 and newer.
- 2020: Releases added Linux NVMe and broader block-device support.

### Related projects

- format-udf depends on platform tools such as mkudffs or newfs_udf and wraps Universal Disk Format workflows. Its README discusses the fake-MBR technique used to improve Windows compatibility for whole-disk UDF volumes.
