Device for deep repairing bottom interfaces of Seagate hard disk and bottom communication method of Seagate hard disk

Abstract

The invention discloses a device for deep repairing bottom interfaces of a Seagate hard disk. The device comprises a TTL master chip circuit board, an USB interface formed in the circuit board and a pin-type plug similar to an audio cable, and further comprises a hole-type interface similar to an audio extension cable and a four-core hole type interface. The USB interface in the circuit board is used for being connected with a PC controller, the four-core hole type interface is connected with a four-core pin type plug in the Seagate hard disk, and the pin-type plug similar to the audio cable is connected with the hole-type interface similar to the audio extension cable. When a TTL master chip is observed from the front face, a tenth pin and a fourteenth pin on the right side are connected with the RXD end and the TXD end of the four-core hole type interface respectively, the four-core hole type interface is connected with the four-core pin type plug in the Seagate hard disk, and bottom information of the Seagate hard disk is obtained through the RXD end and the TXD end. The invention further discloses a bottom communication method of the Seagate hard disk. By means of the device and the bottom communication method, whether next-step processing can be conducted on a fault hard disk through bottom communication or not can be accurately judged.

Description

technical field [0001] The invention relates to a deep maintenance Seagate 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 Seagate hard drives can be recycled and recycled. , unable to read and write and other faults, especially the new Seagate hard drives (especially the latest Seagate models such as Seagate 11, 12, DM002, DM003, etc.) have a common fault. Hardware detection status or LBA=0 failure, under normal circumstances, the user cannot operate through the normal ATA channel port at all, and will be disposed of as waste products.

Problems solved by technology

Among the huge amount of electronic waste generated every year, nearly 70% of Seagate hard drives can be recycled and recycled. , unable to read and write and other faults, especially the new Seagate hard drives (especially the latest Seagate models such as Seagate 11, 12, DM002, DM003, etc.) have a common fault. Hardware detection status or LBA=0 failure, under normal circumstances, the user cannot operate through the normal ATA channel port at all, and will be disposed of as waste products. However, this can be repaired, but there is no good tool yet Reliability testing, regeneration and repair of discarded Seagate hard drives can be carried out. The existing repair process is complicated and the cost of regeneration is high, which limits the recycling rate of Seagate hard drives.
