Device for depth maintenance of bottom-layer interfaces of western digital hard disk and bottom-layer communication method

Abstract

The invention discloses a device for depth maintenance of bottom-layer interfaces of a western digital hard disk. The device comprises a TTL master chip circuit board, a USB interface, a pin-type jack similar to a jack of an audio cable, a hole-type interface similar to an interface of an audio frequency extension cable and a two-row eight-core hole-type interface, wherein the USB interface and the pin-type jack are arranged in the circuit board. The USB interface of the circuit board is used for being connected with a PC controller. The two-row eight-core hole-type interface is connected with a two-row eight-core pin-type jack on the western digital hard disk. The pin-type jack similar to the jack of the audio cable is connected with the hole-type interface similar to the interface of the audio frequency extension cable. Observed from the front, a TTL master chip is connected with an RXD end and a TXD end of the two-row eight-core hole-type interface through a tenth pin and a fourteenth pin on the right side respectively. The two-row eight-core hole-type interface is connected with the two-row eight-core pin-type jack on the western digital hard disk. Bottom-layer information of the western digital hard disk is obtained through the RXD end and the TXD end. The invention further discloses a western digital hard disk bottom-layer communication method. By the adoption of the device for depth maintenance of the bottom-layer interfaces of the western digital hard disk and the bottom-layer communication method, whether next-step processing can be conducted on a fault hard disk through bottom-layer communication can be accurately judged.

Description

technical field [0001] The invention relates to an in-depth maintenance western digital hard disk bottom interface device and a bottom communication method. Background technique [0002] With the increasing popularity of mobile phones, MP4, computers and many other electronic products, the problem of electronic waste pollution is also becoming more and more serious. Among the huge amount of electronic waste generated every year, nearly 70% of Western Digital hard drives can be recycled and recycled. , Unable to read and write and other faults, especially Western Digital hard drives have a common fault, can not be ready after power on, it feels like there is no power on, under normal circumstances, users can not operate through the normal ATA channel port at all, they will be disposed of as waste products However, this can be repaired, but currently there is no good tool for reliability testing, regeneration and repair of discarded Western Digital hard drives. recycling rat...
