Abstract
A method of operating a data storage device is disclosed comprising an enclosure comprising a first head actuated over a first disk surface and a second head actuated over a second disk surface. A manufacture printed circuit board (PCB) is coupled to the enclosure, wherein the manufacture PCB comprises at least one dual channel configured to execute concurrent access operations. While the manufacture PCB is coupled to the enclosure, the data storage device is operated as a dual channel device. The manufacture PCB is decoupled from the enclosure and a product PCB is coupled to the enclosure, wherein the product PCB comprises a single channel configured to execute a single access operation.
