title: read data from ext4 filesystem directly from the raw partition without mounting the file system
body: <p>Is it possible to add data of fixed size to an ext4 image such that its available at the last block of the partition (or say last 100KB)? I want to be able to to add data to the ext4 image such that I can read the data from the corresponding raw partition without any knowledge of the filesystem.</p>
