Publication number: 20060129703Abstract: Embodiments of the invention realize a power-save mode which prevents reduction in performance of a data storage device. The HDD as an embodiment of the present invention, upon receiving a request for switching to a power-save mode (PMREQ) from the host, judges whether the serial interface should be switched to the power-save mode based on the execution status of the command. When the HDD has determined not to switch the serial interface to the power-save mode, the HDD transmits a negative response (PMNACK) to the host and keep the serial interface in the active mode. By denying switching to a power-save mode when data transfer is executed within a short period of time, etc., it is possible to prevent reduction in performance of the data storage device.Type: ApplicationFiled: November 23, 2005Publication date: June 15, 2006Applicant: Hitachi Global Storage Technologies Netherlands B.
