Description of the invention: [Technical field to which the invention pertains] The present invention relates to a computer-related test system, and more particularly to a test system related to a computer hard disk. [Prior Art] The computer's hard disk is equipped with the operating system required to run the computer, installs different application software, and stores the data required by the user. With the development of computer technology and technology, there are also differences in hard disks, such as the difference between the interface of the hard disk and the computer, the difference in the speed of the hard disk, and the like. The hard disk interface is a connection between the hard disk and the host computer system, and functions to transfer data between the hard disk cache and the memory. Different hard disk interfaces determine the connection speed between the hard disk and the computer. In the whole system, the hard disk interface directly affects the running speed of the program and the performance of the system. From a holistic perspective, the hard disk interface is divided into IDE (Integrated Drive Electronics), SATA (Serial ΑΤΑ), SCSI (Small Computer System Interface), and Fibre Channel. IDE and SATA interface hard disks are mostly used in household products. Part of the application to the server, the hard disk of the SCSI interface is mainly used in the server market' and Fibre Channel is only on the high-end server. In addition to the difference in interface between the hard disk and the computer, the speed of the hard disk itself (Rotational Speed), that is, the rotation speed of the motor spindle in the hard disk, that is, the maximum number of revolutions that the hard disk can complete in one minute. It is also one of the key factors determining the internal transfer rate of the hard disk, which directly affects the speed of the hard disk to a large extent. The faster the hard disk speed, the faster the hard disk seek speed, and the relative hard disk transfer speed is improved. Household 6 200817890 Lutong hard disk speed is generally 5400 Revolutions Per Minute (rpm, revolutions per minute), 7200rpm, high-speed hard disk is also the first choice for desktop users. For notebook users, it is 4200rpm and 5400rpm. The server has the highest performance requirements on the hard disk, and the hard disk speed used in the feeder is basically 1000 rpm. The type of computer determines the size of the hard disk. For example, the internal space of the notebook is small, and the size of the notebook hard disk (2.5 inches) is also designed to be smaller than the desktop hard disk (3.5 inch). The computer's specific 'users determine the size of the hard disk. The hard disk used by ordinary users is basically 80G. The notebook computer usually uses 40G or 60G hard disk. The servo is generally more than 100G hard disk. In the operating system, the hard disk must also be partitioned and formatted. Partitioning and formatting the hard disk can better organize and manage the hard disk data. In summary, different hard disks have different parameters. When the computer is equipped with a hard disk, it is necessary to perform some functions on a large number of hard disks to determine the quality of the % hard disk. For example, install the operating system on the hard disk, test whether the hard disk can run normally, format the hard disk, delete the hard disk data, and so on. The traditional method of testing hard disks is to test different parameters of the hard disk through some test software, for example, to test the transmission speed of the hard disk through a test software. When you use a hard disk for a computer, you need to test a large number of hard disks. Different methods are used to test different hard disks for each hard disk. You need to split the hard disk from the computer and replace it with a different hard disk. The types of tests are also different, which takes a lot of time. 7 200817890 ][Inventive content] In view of the above internal communication, it is necessary to provide a hard disk test system that can perform various tests on different hard disks. Similar to the n-type system, which includes a computer and hard disk test device, the motherboard of the south bridge, where the hard disk test device; the brain's motherboard, the hard disk test device includes: to be tested = 11 in the connection The hard disk to be tested is to the south bridge of the motherboard; the button is connected to a button panel controller connected to the motherboard, and the pile: * Yao provides a hard disk test control interface; and the hard disk test module, which is connected with ' The south bridge of the board is used for testing the hard disk to be tested. Can be used to test the hard disk test system provided by the month of the month. For the test work of different hard disk gamma, the test efficiency is improved at ^ time. , Braun test hard disk [Embodiment] System architecture = =, the preferred embodiment of the hard disk test system of the present invention is two: Yes:, Γ includes a computer 1 and a hard disk test device for the phase Hard disk 3G performs a variety of test operations. Alternatively, ==1 may be a PC with a deleted architecture, a PC/spoon computer, or a MAC u using a fabric, which includes a motherboard 10. The body=hard-type device 20 is a body that is capable of mounting a running software, which is connected to the motherboard 10 of the computer J. : Description: The hard disk 30 can be a 3.5-inch hard disk, a 25-inch hard disk 8 inch hard disk, which is connected to the hard disk test device 20 to perform the test. In general, two or three test hard disks to be tested can be performed simultaneously. As shown in Figure 2, the operating system architecture diagram of the hard disk test device in Figure i is shown. The operating system includes the motherboard 10 and the hard disk testing device 2〇. The motherboard 10 includes a south bridge 101 and is coupled to a button panel controller 102. The hard disk test device 20 includes a hard disk test module 2, a hard disk interface 201 to be tested, and a button panel 2〇2. The hard disk test module 200 is connected to the south bridge 101 of the motherboard 1Q. The hard disk test module 200 is a program controlled by the computer i for performing various test operations on the hard disk 30 to be tested. The hard disk interface 201' to be tested may be different interfaces for different hard disks to be tested, such as a SATA interface for a SATA hard disk, or a pATA interface for a PATA hard disk for connecting a hard disk to be tested to a host. South Bridge lOi of board 10. The button panel 202 is connected to the button panel controller 102 for providing a disc test control interface, and the manufacturer can perform various tests on the (four) hard disc. The button panel 202 can be a normal button panel, such as a computer keyboard, a = digit button, etc. It can also be a touch screen button panel, such as a commercial end = a touch screen provided to the user for work. (4) Panel controller ι〇2 its thief, hard disk measurement pull, group 2 〇〇. The button panel control $ can be directly connected to the control expansion card or component of the expansion slot on the motherboard 1G for receiving the hard disk test information of the user using the button panel 2〇2, and controlling the hard according to the received (four) information. The disc module is fine, and the hard disk to be tested is 9 9200817890. As shown in FIG. 3, it is a functional module diagram of the hard disk test module in FIG. The hard disk test module 200 includes a format test module 2001, a partition test module 2002, a data write and delete test module 2003, a speed test module 2004, an operation system test module 2005, and a test result output module. 2006. According to the different function modules included in the hard disk test module 200, the button panel 202 can be set with different buttons to implement different test operations of different function modules, such as setting "format test", "partition test", "data writing". The "Enter and Delete Test", "Speed Test", and "Operation System Test" buttons correspond to the different function modules described above. The format test module 2001 is configured to test whether the hard disk to be tested 30 can be formatted. Hard disk formatting is to divide the hard disk into cylinders and magnetics, and then divide the magnetic disk into several physical magnetic regions, and each physical magnetic region is further divided into identification portions, interval regions, data regions, and the like. The format test module 2001 formats the hard disk 3 to be tested by the south bridge 101, tests whether the formatting operation is successful, and outputs the test result to the test result output module 2006. If the hard disk 30 to be tested can be formatted, the hard disk 30 to be tested is not damaged; if the hard disk 30 to be tested cannot be formatted, the hard disk of the hard disk is damaged or is mad. . The partition test module 2002 is configured to test whether the hard disk 30 to be tested can perform a partitioning operation. When reading the corresponding document of a hard disk, you must give the corresponding rules. For example, the hard disk is usually divided into several areas (C area, D area, E area, etc.), which is a logical partition of the hard disk. The purpose is to save data more reasonably and effectively, and to provide more space for file storage. 200817890 7 A hard disk can have up to 24 logical partitions. The partition test module 2002 performs a logical partitioning operation on the hard disk 30 to be tested through the south bridge 101, tests whether the logical partitioning operation is successful, and outputs the test result in the test result output module 2006. If the hard disk 30 to be tested is capable of logical partitioning, the hard disk 30 to be tested is not damaged; if the hard disk 30 to be tested is not capable of logical partitioning, the hard disk 30 to be tested is damaged or defective. The data writing and deleting test module 2003 is configured to test whether the hard disk 30 to be tested can perform data writing and deleting operations. That is, the hard disk 30 is subjected to the data writing operation and the data testing operation is deleted, and the test result output module 2006 outputs the test result. If the hard disk 30 to be tested is successfully written, but the written data cannot be deleted, it indicates that the hard disk 30 track is damaged or defective; if the hard disk 30 to be tested is unsuccessful, it indicates that the data to be tested is hard. If the hard disk 30 is successfully written, the written data can be successfully deleted, indicating that the hard disk 30 to be tested is not damaged. The speed test module 2004 is configured to test the rotation speed of the hard disk 30 to be tested to determine whether the hard disk rotation speed meets the standard. During the mass production process of the hard disk, the hard disk of different speed standards will be mass-produced according to the requirements. If the hard disk 30 to be tested is in accordance with the mass production standard, it should be a hard disk with a rotational speed of 5400 rpm, and the speed test module 2004 detects the hard disk to be tested 30. If the unit time rotation speed is not equal to 5400 rpm, it indicates that the hard disk 30 to be tested does not meet the standard; on the contrary, if the speed test module 2004 detects that the hard disk 30 unit time speed is equal to 5400 rpm, the hard disk 30 to be tested meets the standard. The speed test module 2004 tests the speed of the hard disk 30 to be tested by collecting the number of rotations of the hard disk to be tested 30 times per unit time; or connecting an infrared measuring instrument, 11 200817890 by controlling the infrared light emitted by the infrared measuring instrument After being reflected by the hard disk 3 to be tested, the reflected wave is received, and the reflected wave is processed to obtain the rotational speed. The operating system test module 2005 is used to test the hard disk drive installation system and test whether the operating system is operating normally. The hard disk test device 2 can be used to protect the operating system file slot that needs to be installed. When the installation hard disk system is required to be tested, the system test system and the hard disk test device 2G backup operation system and system are called. The logo is directly installed on the hard disk to be tested. After the women's wear, the simple operation of the operating system (for example, restarting the computer, restarting the computer i, etc.) is performed. If it can be installed on the hard disk 30 to be tested and can be operated normally (4), the hard disk 30 to be tested is not damaged; if the operating system can be installed on the hard disk 30 to be tested, the computer ί other hardware is normal. When the operating system cannot be operated normally, it means that the hard disk 30 track is damaged or fatigued; if the operating system cannot be installed at all, the hard disk 30 to be tested is damaged or defective. The test result output module 2 〇 〇 6 ' is used to output the test results of the hard disk to be tested. _ test result output module _ can directly display the ^ ^ heart display to the user, can also control the computer i print 5 and prepare, print output test results to the user. ^ Figure 2 shows a detailed example of a hard disk test device in Figure i. H Farming 2〇 The hard disk interface to be tested 2〇1 has been connected to two standbys (pictured - 3.5-inch hard disk and - 2.5-inch hard disk), ^ key panel 2〇2 is set with "format test" ,,, "partition test", "capital:: into the second i test,, "speed test", and "operation system test", know the key, the user can choose to use the above buttons, at the same time - 12 200817890 3·.5-inch hard disk and a Μ inch hard disk for a variety of tests.
