I would like to contribute sleuthkit. Also present in Debian, Fedora, 
Ubuntu, ...

SUMMARY="Tools for analysis of volume and filesystem data"

DESCRIPTION="The Sleuth Kit (TSK) is a collection of command line tools
for disk images.  It allows to analyze volume and filesystem data,
examine disk layout, recover deleted files, etc.  Many partition and
filesystem formats are supported."

libtsk_SUMMARY="${SUMMARY} (runtime)"

libtsk_devel_SUMMARY="${SUMMARY} (development)"


I'm not sure about the LICENSE string:

LICENSE="CPL-1.0 AND GPL-2.0-or-later"

The license/README.md file mentions a bunch of licenses, see comment in 
cygport file. CPL-1.0 is the main license, one separate tool uses 
GPL-2.0-or-later.


The source package supports reproducible builds except for libtsk-devel 
(timestamps in *.a files).

====================
Real world use case: Check whether the SSD TRIM command actually works:

$ # Create a test file (> ~3*256B to prevent resident file)
$ printf 'Line %s\n' {0001..0100} > trim_check

$ # Get full path of file
$ cygpath -am trim_check
D:/tmp/trim_check

$ # Find raw device of partition
$ grep D: /proc/partitions # or: ls -l /dev/disk/by-drive/d
     8    20 629145944 sdb4   D:\

$ # Find inode (here: $MFT index) of file
$ ifind -n /tmp/trim_check /dev/sdb4
339065

$ # Find cluster(s) used by inode
$ istat /dev/sdb4 339065
