- Copy a disk to a raw image file and hash the image using SHA256:

`dcfldd if=/dev/{{disk_device}} of={{file.img}} hash=sha256 hashlog={{file.hash}}`

- Copy a disk to a raw image file, hashing each 1GB chunk:

`dcfldd if=/dev/{{disk_device}} of={{file.img}} hash={{sha512|sha384|sha256|sha1|md5}} hashlog={{file.hash}} hashwindow={{1G}}`
