-e Copy every block, including file system metadata blocks. The output is the entire file system.
-a Display all allocated blocks (same as -e if -A is also given).
-A Display all unallocated blocks (same as -e if -a is also given). This is the default behavior.
-f fstype

given, autodetection methods are used.
-o imgoffset
The sector offset where the file system starts in the image.
-b dev_sector_size
The size, in bytes, of the underlying device sectors. If not given, the value in the image format
is used (if it exists) or 512-bytes is assumed.
-l List the data information in time machine format.
-s Copy only the slack space of the image.
-v Turn on verbose mode, output to stderr.
-V Display version.
image [images]

can be given if the image is split into multiple segments. If only one image file is given, and
its name is the first in a sequence (e.g., as indicated by ending in '.001'), subsequent image
segments will be included automatically.
