Abstract

PURPOSE:To prevent the erroneous destroy of information in a user area by providing a magnetic disk with a switch to show whether a writing operation test can be executed or not, reading the set information and after that, writing into the disk device. CONSTITUTION:When the request of the writing operation test is made concerning a magnetic disk device 4, the set information of a switch 41 of the device 4 is read. The set information is checked and when the test can be executed, the writing operation into the user area is tested. When the test cannot be executed, together with the effect, an inquiry message to change the setting of the switch 41 is displayed on a system console 3, and when a notice to the effect that the setting is changed is inputted from the console 3, the information of the switch 41 is read again and the above-mentioned operation is repeated. Thus, the necessary information in the user area is not destroyed erroneously.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing system, and particularly to a testing method for a magnetic disk drive. [Prior Art] In a conventional magnetic disk device testing method, test information indicating whether or not a user area write operation test has been performed is recorded in an arbitrary location of the magnetic disk device, and the write operation test is performed. At the time of execution, the operator is asked whether or not to execute the test according to the test information of the disk device corresponding to the device number specified by the operator. [Problem to be Solved by the Invention] In the above-described testing method for magnetic disk drives, an inquiry is made to the operator according to the test information of the disk drive corresponding to the device number specified by the operator, and whether or not the disk concerned has been written to. If the disk has not been tested, the operator will have to perform a write test, so if the operator mistakenly specifies a write-protected disk device and makes an inquiry based on the test information. If a response is made by mistake, the information in the write-protected causer area on the disk will be destroyed. [Means for Solving the Problems] A test method for a magnetic disk device of the present invention includes a magnetic disk device including a switch for setting whether or not to execute a write operation test of the disk, and a reading means for reading setting information of the switch. a checking means for checking whether or not the setting information can be tested; and an execution means for performing a write test on the user area of the magnetic disk device if the check results show that the setting information is executable; As a result of the check, if execution is not possible, a message to that effect and an inquiry to change the setting information is displayed, and if the setting information has been changed, the inquiry means notifies the reading means to that effect. . [Operation] Each magnetic disk device is set to allow or not to execute a write operation test, and when testing, the specified magnetic disk device will be asked to execute the test according to its setting information, so write-protected disk devices cannot be used. You can prevent writing about. [Example] Next, an example of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart showing an embodiment of a test method for a magnetic disk device of the present invention, and FIG. 2 is a configuration diagram of an information processing system to which this embodiment is applied. The information processing system of this embodiment includes a central processing unit 1, a memory 2, a system console 3, and a magnetic disk drive 4 having a switch 41. In this information processing system, when a request for a write operation test is issued for the magnetic disk device 4 (step 10
0), reads the setting information of the switch 41 of the magnetic disk device 4 (step 101), then checks this setting information (step 102), and if the test can be executed, performs a write operation test to the user area. (step 103), and if the test cannot be executed in the check in step 102, a message to that effect and an inquiry about changing the settings of the switch 41 is displayed on the system console 3 (
Step 104) If a notification to change the settings is input from the system console 3 (Step 105),
Repeat step 1 and subsequent steps again, including step 102.
However, if the operator determines that the information on the disk device is not necessary at that point, he can change the setting of the switch 41 and perform the write operation test. This means that you can execute [Effects of the Invention] As explained above, the present invention provides a magnetic disk device with a switch that indicates whether or not a write operation test can be executed, and when executing the test, reads the setting information and then writes to the disk device. By doing this, you can perform a write operation test after confirming the necessity of the information stored in the disk device for which the test execution request is requested, and avoid accidentally destroying information in the necessary user area on the disk. This has the effect of eliminating
