| Abstract(in English) | Magnetic disk drives (HDDs) are a representative storage device, which is widely utilized in many places in the society. After being manufactured, HDDs are usually tested in the careful quality verification process and then deployed into practical use. As recent HDDs provide increasingly large-capacity storage space, the conventional quality verification process requires longer test time, becoming almost unpractical. A less-costly verification method is demanded in industry. In order to develop a less time-consuming verification method, we have undertaken an experiment project to understand individual difference and temporal change of the HDD more deeply. This paper reports our experiment and presents our experience. |
