Description
Technical field
The present invention relates to a kind of western number hard disk circuit board reclaim equiment and renovation process.
Background technology
Along with day by day popularizing of many electronic products such as mobile phone, MP4, computer, the electronic waste pollution problem bringing is thus also day by day serious.And in the electronic waste of the annual flood tide producing, there is nearly seventy percent western number hard disk to reclaim and recycling, due to a lot of western number hard disk no powers, motor does not rotate, magnetic head clashes into, cannot be ready, a large amount of bad tracks, the fault such as cannot read and write, particularly trendy western number hard disk has a common fault, because the ROM information of hard disk circuit board is made mistakes, cause after hard disk energising, motor does not run up, with multimeter, measure, there is electricity input, hard disk is not worked completely, by conventional ATA signalling channel, cannot access, CMOS None-identified hard disk, if external rom chip just can directly be changed processing, trendy western number hard disk is cured to rom chip in master chip, allow user oneself cannot change separately rom chip, so that cannot keep in repair by existing conventional method, many times, user can directly scrap these hard disks, the present invention sets forth a kind of method exactly, can accurately judge whether cold trendy western number hard disk belongs to this class fault.This class fault can be keeped in repair, just at present also do not have a kind of good instrument to carry out reliability detection, Regeneration and Repair for the trendy western number hard disk of this class fault, existing repair process is complicated, and regeneration cost is high, and then has limited the recovery utilization rate of western number hard disk.
Summary of the invention
The problem existing for prior art, the object of the present invention is to provide a kind of western number hard disk circuit board reclaim equiment and renovation process, for realizing the bottom communication with western number hard disk, accurately the board state of the western number hard disk of judgement target, determines whether can to carry out degree of depth maintenance to the western number hard disk of target.
The technical solution used in the present invention is: a kind of western number hard disk circuit board reclaim equiment, it is characterized in that: draw together casing and be arranged on the detection control mainboard in casing, TTL master chip circuit board, two row's 8 core cellular type interfaces, supply module, LED display module, keypad load module, disk state electricity pilot lamp group, described detection is controlled on mainboard and is provided with central processing unit, described control mainboard is connected with TTL master chip circuit board by USB wiring position, TTL master chip circuit board is connected with two row's 8 core cellular type interfaces, described control mainboard is connected with the western number hard disk of target by ATA signaling interface line,
Described supply module is the western number hard disk power supply of western number hard disk circuit board reclaim equiment and target, described two row's 8 core cellular type interfaces, supply module are connected with the western number hard disk of target, and described keypad load module is connected with control mainboard respectively with LED display module, disk state electricity pilot lamp group.Described TTL master chip is from top view, RXD end by right side the tenth pin and the 14 pin respectively with two row's 8 core cellular type interfaces is connected with TXD end, described two row's 8 core cellular type interfaces connect the row of two on western number hard disk 8 core pin type sockets, by RXD and TXD end, obtain western number hard disk bottom-up information.Described disk state electricity pilot lamp group is comprised of ready lamp, read signal lamp, the signal lamp that writes letter.
In addition, also relate to a kind of western number hard disk circuit board renovation process, with the supporting hard disk circuit board of western number hard disk circuit board reclaim equiment regeneration software, the western number hard disk circuit board reparation that hard disk circuit board regeneration software can be made mistakes ROM information, so just can carry out degree of depth maintenance to the western number hard disk of target.Hard disk circuit board regeneration software contacts good in the situation that at definite total interface, first set (parameter area 9600-128000) after virtual com port (parameter area 3-6) and baud rate, whether the ready lamp of observing disk state electricity pilot lamp group is bright, if bright, just represent it is because the circuit board of the western number hard disk of target is manipulable; If ready lamp does not work, just must first change or repair circuit plate after test again.The most common failure that causes ready lamp not work comprises: circuit board component damages, circuit board breaks, the power interface of circuit board is bad, rom chip damages, the signaling interface of circuit board is bad etc.The maintenance of the described degree of depth specifically comprise change circuit board, change circuit board interface, change magnetic head, change motor, rewrite ROM, subdue magnetic head number, repair firmware, LBA=0 is repaired in instruction, remove firmware lock, rebuild decoding table, process G defect map and P defect map, harddisk password release, disk fall appearance, fall density, the SF self-correcting reparation after reduction of speed, optimization.The western number hard disk bright for ready lamp first carries out ROM information back-up, during information back-up, the read signal lamp of disk state electricity pilot lamp group is bright, representative has ROM information to back up, read signal lamp does not work, whether representative does not have ROM information to back up, or backs up unsuccessfully, no matter back up, successfully all carry out ROM information and write.ROM information write be by keypad load module input instruction (parameter area 1-16, wherein instruction 1 is that representative writes the general ROM-1 program of 160G to the ROM of the western number hard disk circuit board of target; Instruction 2 is that representative writes the general ROM-2 program of 160G to the ROM of the western number hard disk circuit board of target; Instruction 3 is that representative writes the general ROM-1 program of 250G to the ROM of the western number hard disk circuit board of target;
