Problems solved by technology

In the case of a large output of hard disks, the frequent removal and removal of hard disks reduces the efficiency of hard disk detection, and it is not only time-consuming for workers to remove the hard disk from the test device and then install it into the computer for trial use, but also very inconvenient to operate.

Embodiment Construction

[0009] A kind of dual-purpose hard disk test adapter 10, combines figure 1 , which can be used for communication between the computer 20 and the hard disk 30 under test or signaling transmission between the hard disk testing device 40 and the hard disk 30 under test. In this embodiment, the hard disk adopts the ATAPI interface. Other interfaces such as 1394 and USB can also be used.

[0010] The dual-purpose hard disk test adapter 10 includes a serial port adapter interface board 12 , a parallel port adapter interface board 14 and a power supply circuit 18 for supplying power to the hard disk.

[0011] The serial adapter interface board 12 complies with the TX / RX serial data transmission standard, and includes two data interfaces J5 and J6. The data interface J5 is connected to the serial port SP2 of the hard disk testing device, and the data interface J6 is connected to the serial port SP1 of the testing hard disk. When the serial port adapter interface board 12 is working...

Abstract

This invention relates to a dual-purpose adapter for hard disk test. Wherein, the adapter comprises a serial adapting interface board with ends connected to the serial ports of the testing device and HD respectively for signaling transmission, a power-supply circuit for HD, and a parallel adapting interface board that connects to a computer and the HD and comprises a couple of IDE interfaces connected to the computer data interface and the HD IDE interface respectively for the communication between computer and HD.

Description

【Technical field】 [0001] The invention relates to a hard disk testing device, in particular to a dual-purpose adapter device capable of testing and trialing hard disks during the hard disk manufacturing process. 【Background technique】 [0002] After the production and assembly of the existing hard disk is completed, a series of single-step command tests and comprehensive simulation tests need to be performed on the hard disk, such as power on, power off, motor rotation, servo positioning, writing to a specified track, and so on. Each hard disk is equipped with a serial port to transmit the instructions of the hard disk test. Usually after the hard disk is tested and its parameters are optimized, it needs to be tried on the computer to confirm the function and operation of the hard disk being debugged. After the diagnostic test, the traditional hard disk needs to be taken off from the testing device, and then put into the computer for trial use. In the case of a large outpu...
