SPOILER ALERT!
Repair alternatively of discarding the actual difficult disk firmware repair.
For faulty difficult drives which have passed the warranty period, most customers will opt for to discard or disassemble for play. But for the true DIYer, picking out to repair the failed difficult drive is the 'right way'. Please be assured that repairing the hard drive does not necessarily must invest revenue outdoors, and there is a specific possibility of resurrection in the event you do it your self.
Rescue the 'death penalty' challenging drive
I have a failed Western Digital hard drive on hand, and following DLG software detection prompts that it cannot be repaired (Figure 1), I contacted the manufacturer and stated that the assured hard drive can no longer enjoy the official after-sales. So far, the difficult drive has been fundamentally sentenced to death. The superior news is the fact that there is nevertheless a silver lining for this kind of faulty difficult drives, that is to 'rescue' inside the kind of 'pass the brush'.
01
Passing brush demands the cooperation of tool application and pass brush firmware. Taking my Western Digital really hard drive as an example (Tips 1), the tool computer software is at present out there available with effective source technology of Western Digital specialty (given that it involves computer software and hardware, it can be only appropriate for Western Digital specialty User) and WDR (a Western Digital upkeep tool developed in China, which is often downloaded around the repair web-site or forum which include CHINAFIX to download the software program and supporting firmware for a wider coverage).
Additional reading: What exactly is pass-through?
Officials ordinarily use 'automatic calibration' to repair the hard disk. The function of automatic calibration is like the factory test process on the manufacturer, which will automatically shield the defects on the really hard disk. What we call pass-through is firmware which can be self-calibrated. It really is compatible with all the same board quantity and household maintenance firmware. The supply is frequently to work with the disk returned by the manufacturer to clear all LOG and defect lists, and generate the firmware backed up just after the factory upkeep approach (Guidelines 2). For the reason that this sort of firmware is utilised for maintenance by the factory, the general P meter (modest tip 3) is considerably larger than the original disk firmware. As delete partition data recovery software , the 1640-pass firmware P table includes a total capacity of 250,000 on each heads, as well as the original disk is commonly tens of thousands. complete.
Tip 1: At present, all brand challenging drives could be self-calibrated, which include WD.ST, and so forth., but each and every brand includes a unique way of beginning. By way of example, ST may be started by way of the COM port with instructions (we will introduce the ST component when there is certainly a possibility).
Tip 2: Why will be the repair disk alternatively of a commercially readily available hard disk, because many of the difficult disks on the market, most of their approach tables happen to be destroyed, which leads to the repair effect from the hard disk after the really hard disk repairer starts calibration
Tip three: P-list will be the permanent defect list, which is a list of defects generated by the manufacturer before the challenging disk leaves the factory. It will likely be automatically avoided when the hard disk is operating; corresponding to it's the G-list, that is a list that appears and records through the use of your really hard disk. Also called development defect table. Every difficult disk has P table and G table.
Preparation prior to brushing
Take WDR as an instance, the basic method of flashing is: backup the original disk firmware (ROM and firmware module) → make use of the maintenance software to create the corresponding board number and family of flashing ROM, reset after writing → create the quantity 47 within the original disk ROM Adaptation module, reset → create back the firmware module (create module 0001 initially, and after that create other modules), reset → set DCM, reset → set LBA, reset → start out self-calibration → separate power-on → verify once again right after calibration to confirm the maintenance effect .
hard disk deleted partition recovery software seems complex, but we only ought to grasp the following key points to effectively comprehensive the complete repair process:
Since the repair is according to the board quantity and family, it's essential to ascertain the board number of the failed really hard drive ahead of time. The circuit board quantity is visible on the difficult disk physique (Figure two). Taking the author's challenging disk as an instance, 1672 is its board number.
02 Brush firmware is distinguished as outlined by the circuit board number and loved ones, the circuit board number can refer towards the red underlined component
Additionally, the really hard disk family can pass the detection data in WDR, but the most precise is always to look in the C5 module inside the firmware, which consists of the family members number info. The firmware file backed up in WDR is named ~id00C5.rpm, which may be observed by opening the C5 module utilizing winhex or other binary editor (Figure 3). Considering that you'll find difficulties with the general state from the tough disk to become repaired, it might bring about the Windows technique to begin gradually or perhaps go incorrect. If you want to improve the repair speed, you may wish to use WinPE to begin, that will let us worry lots.

Sometimes, if the incorrect ROM is refreshed, it may lead to disk knocking, and it can be impossible to write the ROM file at this time. At this time, you should switch to PCB mode (that may be, circuit board mode) to rewrite the appropriate ROM file. We can enter the PCB mode by short-circuiting the two points on the circuit board when starting up (Figure 4).

Really hard disk brush
Before flashing, you have to back up the original flash and ROM modules on the tough disk. The ROM consists of 0A; 0B; 0D; 30; 4F; 47 total six modules (Figure 5), which may be split in the backup ROM file come out. We will use it when the 47 modules are flashed. It is the firmware area adaptation parameter. The factory adaptation parameters on the original disk will have to be probably the most appropriate for the original disk. Next, the firmware module needs to be backed up (Figure 6).
05 Note: Operate based on the illustration, 'read out' is definitely the backup
06 Note: Read all firmware modules
Just just like the initially grid disk is essential when reinstalling the system, immediately after the backup is performed, we also ought to format the firmware area of the dilemma tough disk (Figure 7). Next, you should create the corresponding board quantity and household brush ROM (Figure 8). When the head is changed (which include head cutting), you must edit the head position and create it, after which reset the energy. Soon after writing the flash ROM, please return towards the Flash operation window, create the 47 modules inside the original ROM (Figure 9), after which reset the power.
07 Note: Just follow the icon, the firmware region can also be referred to as reserved region
08 Note: Here you have to make a choice depending on the original disk, one example is, the original disk is 0.1.2, then you definitely can pick as you like here
09
When flashing the module, you should initially write the module No. 0001 (Figure ten: Note: Some circuit board models ought to load the boot module just before writing the module, including 1640), and then write the remaining modules (Figure 11), create Complete the power reset and complete the reset.

If you need to modify the challenging disk, you should create the module. The address of the difficult disk firmware location where module 0001 is located is fixed, while the addresses of other modules are specified by module 0001. In the event the 0001 module cannot be written, either the head is damaged or the firmware is unusable. Consequently, module 0001 should be written before other modules might be written.
Just before self-calibration, we also should set DCM and LBA. Immediately after setting the DCM, the disk density and capacity may be initialized, provided that you click DCM and after that click OK. The default is 1 or 2 (Figure 12), and after that reset the power. If the LBA calibration just isn't set, errors will take place throughout the calibration approach, so be sure that the values of LBA0.LBA1.LBA2 and HPA are the identical (Figure 13). In the same time, the model quantity and SN number may also be modified accordingly, for instance, it can be changed for the pinyin initials + numbers of pc enthusiasts, then reset the energy.

Ultimately, click the start off self-calibration button (Figure 14). At this time, PST has not started running. We ought to power off and reset once to begin running. In the event the quantity of maintenance disk is reasonably massive, you could do offline at this time, the approach will be to remove the hard disk at this time, connect it to a separate energy supply, hang the disk and run the calibration. Of course, you can also run on the net. Following resetting, you can start off operating in about a minute.

The benefit of offline operating is energy saving, plus the disadvantage is that you cannot see the status; the benefit of on the web running is the fact that you'll be able to see the status, plus the disadvantage is the fact that it really is not environmentally friendly. As for the calibration time, according to the state from the hard disk, basic desktop difficult disks demand 160-160 hours for 3 to five hours, 320G for six to 10 hours, and so on, the notebook disk is about half as slow.
summary
It might occasionally take us a lot of time to repair IT product repairs, but in this process we are going to learn loads of understanding which has not been touched. In reality, the crucial is this repair process, not the final result.
