Seagate hard disk circuit board detection equipment and detection method

Abstract

The invention discloses Seagate hard disk circuit board detection equipment, which comprises an enclosure, a detection control mainboard, a TTL (transistor-transistor logic) main chip circuit board, one row of four-core hole type interface, a power supply module, an LED display module, a keypad input module and a hard disk state electric indicating lamp group, wherein the detection control mainboard is provided with a central processing unit; the control mainboard is connected with the TTL main chip circuit board by a USB wiring position; the TTL main chip circuit board is connected with one row of four-core hole type interface; the control mainboard is connected with a target Seagate hard disk by an ATA signal interface wire; the power supply module supplies power to the Seagate hard disk circuit board detection equipment and the target Seagate hard disk; the row of four-core hole type interface is connected with the power supply module and the target Seagate hard disk; and the keypad input module, the LED display module and the hard disk state electric indicating lamp group are each connected with the control mainboard. The invention also discloses a Seagate hard disk circuit board detection method which can be used for precisely judging the state of the Seagate hard disk circuit board so as to confirm whether deep maintenance can be carried out to the target Seagate hard disk.

Description

technical field [0001] The invention relates to a detection device and a detection method for a Seagate hard disk circuit board. 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, Seagate hard disk has a common fault, because the firmware information of the hard disk circuit board is wrong, the hard disk cannot be ready after power-on. etc. Through the conventional ATA signal channel, the hard disk cannot be accessed, the CMOS cannot recognize the hard disk, and the conventional software cannot operate, so that it cannot be repaired. In many cases, users will directly scrap these hard disks. Does the new Seagate hard drive that is powered on bel...

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, Seagate hard disk has a common fault, because the firmware information of the hard disk circuit board is wrong, the hard disk cannot be ready after power-on. etc. Through the conventional ATA signal channel, the hard disk cannot be accessed, the CMOS cannot recognize the hard disk, and the conventional software cannot operate, so that it cannot be repaired. In many cases, users will directly scrap these hard disks. Does the new Seagate hard drive with power belong to this kind of failure

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