Features

Analyzes a disk image getting information about the disk itself and analyzes partitions and filesystems inside them
Can checksum the disks (and if optical disc, separate tracks) user-data (tags and metadata coming soon)
Can compare two disk images, even different formats, for different sectors and/or metadata
Can list and extract contents from filesystems that support that
Can read several disk image formats.
Can read several known sector by sector formats with variable bytes per sector.
Can read standard sector by sector copies for optical and magnetic discs with constant bytes per sector.
Can verify sectors or disk images if supported by the underlying format
