A data storage device is disclosed. In one embodiment, the data storage
device has a maximum storage capacity and is initially limited to
providing access to a limited amount of data storage capacity that is
less than the maximum data storage capacity. The size of the limited
amount of data storage capacity is variable based on an indication of how
much of a collection of advertising material has been viewed. In one
embodiment, a host system manages a transfer of all or a portion of the
collection of advertising material to a storage location on the data
storage device. In one embodiment, the same host system manages
adjustments to the size of the limited amount of data storage capacity
based on how much of the collection of advertising materials has been
consumed.
