Detecting device and detecting method for western digital hard disk circuit board

Abstract

The invention discloses a detecting device for a western digital hard disk circuit board. The detecting device comprises a shell, a detection control main board, a TTL master chip circuit board, two rows of eight-core hole ports, a power supply module, a light emitting diode (LED) display module, a keypad input module and a hard disk state electrical indicator light group, a central processing unit is arranged on the detection control main board, the control main board is connected with the TTL master chip circuit board through a universal serial bus (USB) wiring position, the TTL master chip circuit board is connected with the two rows of eight-core hole ports, the control main board is connected with a target western digital hard disk through an ATA signal interface wire, the power supply module supplies power for the detecting device of the western digital hard disk circuit board and the target western digital hard disk, the two rows of eight-core hole ports, the power supply module and the target western digital hard disk are connected, and the keypad input module, the LED display module and the hard disk state electrical indicator light group are connected with the control main board respectively. A detecting method for the western digital hard disk circuit board is further disclosed, the circuit board state of the target western digital hard disk can be accurately determined, and whether deep maintenance is allowed to be performed on the target western digital hard disk or not can be determined.

Description

technical field [0001] The invention relates to a Western Digital hard disk circuit board detection device and detection 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 the new Western Digital hard disk has a common fault, because the ROM information of the hard disk circuit board is wrong, resulting in the hard disk motor not turning after power on, if it is an external ROM chip, it can be replaced directly However, the new Western Digital hard disk solidifies the ROM chip into the main chip, so that the user cannot replace the ROM chip alone, so that it cannot be repaired by the existing conventional methods.

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 the new Western Digital hard disk has a common fault, because the ROM information of the hard disk circuit board is wrong, resulting in the hard disk motor not turning after power on, if it is an external ROM chip, it can be replaced directly However, the new Western Digital hard disk solidifies the ROM chip into the main chip, so that the user cannot replace the ROM chip alone, so that it cannot be repaired by the existing conventional methods. In many cases, the user will directly scrap these hard disks. A method that can accurately determine whether a new Western Digital hard drive without power belongs to this type of fault

This kind of failure can be repaired, but there is no good tool for reliability testing and regeneration repair of the new Western Digital hard disk with this kind of failure. The existing repair process is complicated and the regeneration cost is high, which limits the Western Digital Hard Drive Recycling Rates
