Abstract: Methods, systems, and devices are described for a data storage device, such as a hard disk drive or solid state drive, that may be initially formatted to an initial capacity. The data storage device may continue to be formatted to add additional capacity to the device. In some examples, a data storage device may be shipped from a factory having an initial capacity, with formatting completed in the field. According to certain examples, the additional capacity may be provided to a user of the data storage device upon satisfaction of one or more conditions. For example, a user may purchase additional capacity, upon which the data storage device may be instructed to provide the additional capacity for use by the user.
