Testing/adjusting method and test control apparatus for rotating disk storage devices
First Claim
1. A method for testing/adjusting a rotating-disk-type storage device connected to a host device via a data transmission path, the method comprising:
- the host device transferring the test/adjustment program of a first phase that is stored within the host device, to the rotating-disk-type storage device;
the rotating-disk-type storage device executing the test/adjustment program of the first phase;
the host device detecting that the rotating-disk-type storage device is requesting a transfer of the test/adjustment program of a second phase that is stored within the host device; and
in response to the request in the detecting, the host device transferring the test/adjustment program of the second phase to the rotating-disk-type storage device.

Abstract
Embodiments of the invention provide a method of testing/adjusting magnetic disk devices, in which the method allows the tests/adjustments to be conducted by solving problems due to the data sizes and characteristics of test/adjustment programs. After assembly of a magnetic disk device, setup of various parameters, magnetic disk defect registration, and other test/adjustment steps are executed. Execution of the test/adjustment programs does not require a special test apparatus since they are executed in the magnetic disk device to be tested. In addition, the test/adjustment programs are formed up of multiple phases, and each phase is sequentially executed. Adoption of this program structure keeps the tests/adjustments clear from restrictions due to the data sizes and characteristics of the test/adjustment programs.
