Description

technical field [0001] The invention relates to the technical field of hard disk testing, in particular to a hard disk drive power chip testing method and system. Background technique [0002] As the data storage of the computer system, the hard disk is mainly used to store data. The hard disk is divided into mechanical hard disk and solid-state hard disk. The mechanical hard disk is a traditional ordinary hard disk. Composition, the magnetic head can move along the radial direction of the disc, coupled with the high-speed rotation of thousands of revolutions per minute, the magnetic head can be positioned on the designated position of the disc to read and write data, and the information passes through the magnetic surface very far away The magnetic head is close to the electromagnetic current to change the polarity and is written to the disk by the electromagnetic current. Compared with the traditional mechanical hard disk, the structure of the solid-state hard disk is much...

Problems solved by technology

[0003] With the development of informatization, hard disks are used in various types of computers. However, since the hard disk must be charged with equipment to run, it needs to be installed before testing, and most of the time, the internal damage is not obvious, and there are read and write data. It is difficult for users to detect the problem of not being smooth. When the hard disk is found to be completely damaged, the data has been lost, causing unnecessary losses.

At present, there is a lack of direct detection methods for hard disks. Therefore, it is necessary to design a precise and comprehensive test method and system for hard disk drive power chips.
