No it isn't. Data is alignment of magnetic particles. The particles are always there, representing some kind of information, regardless of how much of its space is occupied by coherent "data" stored there deliberately by humans.
Complexity doesn't refer to the number of bits that can have a 1 or a 0 set. It refers to systems or parts that have relationships and interact with other systems or parts. Random bits on a drive are not interecting with with anything nor do they have any structure to do so. There is no definition of complexity that would even suggest that sectors on a drive with a random value are equally as complex as a drive holding a database or files.
