When running md5deep in piecewise mode where the file specified is a block device (/dev/sda etc.), the last line of output is bogus. For example:

...
16f38c6af71859a3a540b00e131b19a0 offset 249443647488-249477201919
65f0a3d974de9dc4862792cc3a4cb5b8 offset 249477201920-249510756351
d41d8cd98f00b204e9800998ecf8427e offset 249510756352-249510756351

The highest byte offset in this case was 249510756351. The hash on the last line is of zero bytes (i.e. no data / nothing).
