Western Digital hard disk reclamation equipment and reclamation method

Abstract

The invention discloses a Western Digital hard disk reclamation equipment, which comprises an enclosure, a detection control mainboard, a TTL (Transistor Transistor Logic) main chip circuit board, two rows of 8-core hole type interfaces, a power supply module, a LED (Light Emitting Diode) display module, a keypad input module and a hard disk state electricity indicator light group, wherein the detection control mainboard is provided with a central processor; the control mainboard is connected with the TTL main chip circuit board through a USB wiring position; the TTL main chip circuit board is connected with the two rows of 8-core hole type interfaces; the control mainboard is connected with a target Western Digital hard disk through an ATA (Advanced Technology Attachment) signal interface cable; the power supply module supplies power to the Western Digital hard disk reclamation equipment and the target Western Digital hard disk; the two rows of 8-core hole type interfaces, 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 electricity indicator light group are respectively connected with the control mainboard. The invention also discloses a Western Digital hard disk reclamation method. Hard disk reclamation software can repair a Western Digital hard disk circuit board with wrong ROM information, and therefore, the target Western Digital hard disk can be subjected to deep maintenance.

Description

technical field [0001] The invention relates to a Western Digital hard disk circuit board regeneration device and regeneration 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 drive has a common fault, because the ROM information of the hard drive circuit board is wrong, resulting in the hard drive, the motor does not turn on after the power is turned on. Measure with a multimeter, there is power input, the hard drive does not work at all. Work, through the conventional ATA signal channel, can not access, CMOS can not recognize the hard disk, if it is an external ROM chip, it can be replac...

Problems solved by technology

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 drive has a common fault, because the ROM information of the hard drive circuit board is wrong, resulting in the hard drive, the motor does not turn on after the power is turned on. Measure with a multimeter, there is power input, the hard drive does not work at all. Work, through the conventional ATA signal channel, can not access, CMOS can not recognize the hard disk, if it is an external ROM chip, it can be replaced directly, but the new Western Digital hard disk solidifies the ROM chip into the main chip, so that users cannot replace it alone ROM chip, so that it cannot be repaired by existing conventional methods. Many times, users will directly scrap these hard disks. This invention describes a method that can accurately determine whether a new Western Digital hard disk without power belongs to this type of failure.

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
