.. py:function:: read_footer(fh)


.. py:class:: VHD(fh)


   Bases: :py:obj:`dissect.util.stream.AlignedStream`

   Basic buffered stream that provides easy aligned reads.

   Must be subclassed for various stream implementations. Subclasses can implement:
       - _read(offset, length)
       - _seek(pos, whence=io.SEEK_SET)

   The offset and length for _read are guaranteed to be aligned. The only time
   that overriding _seek would make sense is if there's no known size of your stream,
   but still want to provide SEEK_END functionality.

   Most subclasses of AlignedStream take one or more file-like objects as source.
   Operations on these subclasses, like reading, will modify the source file-like object as a side effect.

   :param size: The size of the stream. This is used in read and seek operations. None if unknown.
   :param align: The alignment size. Read operations are aligned on this boundary. Also determines buffer size.

   Bases: :py:obj:`Disk`

   .. py:method:: read_sectors(sector, count)



.. py:class:: BlockAllocationTable(fh, offset, max_entries)


   Implementation of the BAT.

   Entries are uint32 sector offsets to blocks in the file.
