Bit-stream imaging is the method utilized by Ruben in the above scenario. Bit-stream imaging is a method that involves creating a cloned copy of the entire media and prevents the contamination of the original media. Bit-stream imaging copies all the data on the media, including deleted files and folders, hidden partitions, slack space, etc., at a bit level. Bit-stream imaging preserves the integrity and authenticity of the digital evidence and allows further analysis without affecting the original media. Sparse acquisition is a method that involves creating a partial copy of the media by skipping empty sectors or blocks. Drive decryption is a method that involves decrypting an encrypted drive or partition using a password or a key. Logical acquisition is a method that involves creating a copy of the logical files and folders on the media using file system commands.
