1. An information processing apparatus comprising:
- a processor; and
a disk drive comprising a disk storage medium and a nonvolatile memory device, wherein the disk drive is configured to execute a self-diagnosis function, to store diagnosis information in the nonvolatile memory device, and to read out the diagnosis information from said nonvolatile memory device to send said diagnosis information to the processor when the disk drive receives a diagnosis information read-out request from the processor.

Abstract
According to one embodiment, an information processing apparatus that includes a processor and a disk drive, in which the disk drive includes a disk storage medium and a nonvolatile memory device, and is configured to execute a self-diagnosis function and stores diagnosis information obtained by the self-diagnosis function, in the nonvolatile memory device. When the disk drive receives a diagnosis information read-out request from the processor, the disk drive reads out the diagnosis information form the nonvolatile memory device to send the diagnosis information to the processor.

7. An information processing apparatus that may be powered by one of either a battery or an external power supply, the apparatus comprising:
-
a disk drive that comprises a disk storage medium and a nonvolatile memory device, wherein the disk drive is configured to execute a self-diagnosis function, and to store diagnosis information that is obtained by the self-diagnosis function either the disk storage medium or the nonvolatile memory device; means for causing a display device to display a prompt that permits a user to select one of either a first mode in which the diagnosis information is stored in the disk storage medium, a second mode in which the diagnosis information is stored in the nonvolatile memory device, or a third mode in said diagnosis information is switched between either the disk storage medium and the nonvolatile memory device or vice versa depending upon the type of a power supply used for powering the information processing apparatus; means for sending a command that instructs that the diagnosis information be stored in the disk storage medium if the first mode is selected by the user or the nonvolatile memory device if the second mode is selected by the user; and means for determining whether the information processing apparatus is being powered by the battery or the external power supply if the third mode is selected by the user and for sending a command, that instructs either that the diagnosis information be stored in the disk storage medium if the apparatus is being powered by the external power supply or the nonvolatile memory device if the apparatus is being powered by the battery.

8. A method for controlling a disk drive provided within an information processing apparatus comprising a processor and the disk drive, the apparatus being configured to be powered by one of either a battery or an external power source, the disk drive comprising a disk storage medium and a nonvolatile memory device and configured to execute a self-diagnosis function, the method comprising;
-
storing diagnosis information obtained by the self-diagnosis function in one of either the disk storage medium or the nonvolatile memory device depending upon a command sent from the processor to the disk drive; determining whether the diagnosis information is stored in the nonvolatile memory device or in the disk storage medium in response to a diagnosis information read-out request sent from the processor to the disk drive; and reading out the diagnosis information from either the nonvolatile memory device or the disk storage medium, depending upon where it is stored, and sending the diagnosis information to the processor. - View Dependent Claims (9, 10)
