The dialog box lists models and modes of program startup(the default startup mode is the common mode) supported by Western Digital（namely WD）. Users can manually select the model or automatically detect, after selecting the mode, click “Startup” button to enter the interface of WD Professional Tool.

“Common Mode” is used for HDD to normally visit and each module can be normally opened .

If in “common mode ”, HDD can’t be normally ready or can't read the information of ROM, RAM and other models, users can select “Kernel Mode”or "Diagnostic Mode" according to practical situation. In the two modes, the program will carry on the special treatment on HDD; the program enhanced the processing capacity of HDD failures.

In some circumstances, the program can't normally acquire HDD SPI information and so on, at this time it will pop up a dialog box (As shown in figure 1.1-2). The program below the figure will calculate a default SPI and then fill it in the editor box based on having gained other data. In general, users don’t need to modify it.

Figure1.1-2Input SA SPT

When HDD disks of “Safe Mode ” stops turning, users can only visit the module information on PCB Board, namely to say that can only visit ROM information and can't visit the content of HDD disks so as to achieve the purpose of avoiding change the disk content.

“Diagnostic Mode”is MRT Firmware Laboratory to develop the repair function for WD Series HDD, when HDD can’t be normally ready, users need to manually “short circuit” HDD Safe Jumper. Then when the program boots, select “Diagnostic Mode”, click “Automatic acquisition model”or manually select the mode, after starting the program , users are required to set up working folder to save mode information(as shown in figure 1.1-3 ) so as to restore initial statue of HDD when errors occur. The dialog box lists models and modes of program startup(the default startup mode is the common mode) supported by Western Digital（namely WD）. Users can manually select the mode or automatically detect, after selecting the model, click “Startup” button to enter the main interface of WD Professional Tool.

Figure 1.1-3 Set up working folder

These different startup modes will demonstrate in the supporting instruction for use of video tutorial.

Main Interface

The Main Interface of WD Professional Repair Tools, all the operations by users will be recorded in log page. As shown in figure 2.0 – 1.

2.1 – 1（WD Module Main Interface）

The design of the main interface is mostly similar to UDMA to meet the majority of users’ habits. In “HDD Information”, it is very convenient for users to view the model of HDD, Series Number, capacity and Firmware Version Information. “Other Information” also contains the abundant information, for example as you view, it not only contains “Family Information”, but also the “Track, Head, SPI” of SA area, there are still ROM version and Startup Mode information. The right side of toolbar contains the shortcuts of “Soft Reset”, “Hard Reset”, “Sleep”, “Wake Up”, “Calibration”, " ABA approach read and write HDD "" ID read and write””track read and write” and other functions from the top to the bottom. Through our well-designed, all these provide the convenience and flexibility of operation for users.

Menu and Main Functions

WD Professional Tool Function is mainly concentrate on the "Diagnostics", "Service Area Operations", "Tools” three menus; each menu structure is as follows:

2.1 Diagnosis

2.1 – 0（Diagnosis Menu）

Its submenu item sequence as shown in figure 2.1.1 – 1, we will explain one by one.

2.1.1View Basic Information

“HDD Information”submenu can display the current basic HDD information in the form of the dialog box, and it can detect HDD again. As shown in figure 2.1-1.

2.1.2 Service Area Operation

2.1 - 2

For the convenient use for users, we remove ROM Operation in the sub-menu item of SA menu, integrate RAM Operation and single it out as a top-level menu. As shown below:

2.1 - 3

Although we don’t extract ROM, RAM, they can be easily searched in the main interface.

2.1 - 4

Use the mouse to click that icon represents “Chip”, ROM-related operations will come out, RAM operating is on its side.

Below we take the figure2.1-1 for example, explain one by one from the top to the bottom.

1. Full Backup Resource

.Obviously, this function will backup the entire resource of HDD, including Module, Track as well as ROM.

3. ROM Operation

① ROM List

The toolbar above from the left to the right is: "Close Tab", "View the selected Module ", "Stop Task" "Turn to the first row" "Turn to log page" "SA structure detection”.

Double-click Module Item, or click to view the selected module, it will jump into HEX Page (16 Hex Editor Page).

As shown, the figure displays 20B module, on the Hex Page, it can view modify, write into, calibrate, seek , carry on filling characters in the specified area, copy, paste, save it as the file or open the backup file and other operation to the data of module. If the data of module is wrong, it is very convenient for us to edit it. Similarly, when we talk about the common module list later, at the same it will jump to this interface, but data displayed is the module that we clicked.

② Edit Head Bitmap

The operation is simple, if we detect one head breaks down, we don’t need to start the head, so we can tick it off here, then click “OK”. Above is the option “Default Configuration”, we will change the switch of head bitmap if we select the option, and then we are not allowed to edit head bitmap, HDD itself will choose the non-default head bitmap to use.

③ Diagnosis ROM

The menu contains two kinds of functions, one is ROM data detection module, and the other is the overall ROM data detection. At the present, it only supports ROM data detection module.

④ Save ROM

Obviously，it will save the entire ROM，users themselves can choose where to save.

⑤ Write into ROM.

The file is selected by users to write into ROM, and then click “OK.”

⑥ Save ROM Module

It is for us to select the backup path, and we can check any module need to be backed up in the checkbox, and we can see the program still provides the right-click menu, which it is very convenient for us to select. Click “Start” button to begin to backup.

⑦Write into ROM Module

You can see the interface similar to interface of saving ROM interface. Click “Browse” to select rom module folder backed up just now, the list box will appear the information of module that has already been backed up. Check any file that we need to write into, click “Write into” to begin the task.

⑧Rebuild ROM from SA.

There is no doubt that the function of “Rebuild ROM from SA” in MRT is very powerful. From the figure, we can see that we firstly need to select the path of file needs to be saved. If check “Save the File” button, the program will save both the source file and the newly-built file to the selecting file during the course of generating ROM. Since this function extract from module data of SA service area, through the algorithm and merger to generate the new file, so if SA data is wrong, it will lead to the new generation of data is also incorrect. Thus, it will strictly detect SA module data in the process of generation, so under some circumstances, it will generate the log report with red words during the course of generating the new file. As shown below：

Here can only list one part of log because of the problem of inadequate interface. If here appears red words, please take it easy and observe the log above, we can see there are significantly separated when generate different kind of modules. For example the figure above：“Rebuild 30。。。”to“Rebuild 30 ： …………: OK”is the information of generating 30 modules. Red words in the middle of figure are to detect the incorrect related data in the process of generating 30 modules, so the next sentence translated into Chinese is “it will take another way to generate 30 modules.”Finally, we can see the second way to generate 30 modules turns out a success.

Now we can draw a conclusion, to ensure the success of generating ROM, the program will firstly use one way to generate during the course of generating each module. If the first way to generate is unsuccessfully or detect the incorrect generating data, then it will start the second way continue to generate.

3. RAM operation

① Edit RAM Head Bitmap

② Load LDR

If the folder selected to backup modules exists 11.rpm, 13.rpm and other documents，they will be listed in the list, there are three kinds of loading modes geberally11 to choose the first way, 13 to choose the second way. Click “Load” button to begin to load.

③ The way of operation is the same with loading LDR.

Operation way is same as loading LDR.

4. Module Object Operation

①Batch Backup Module

The same to save ROM module mentioned before, it is decided by us to select the backup path and we can select any modules need to be saved, provides the right-click menu to make operation conveniently. The difference is that we can also choose the way of reading data from HDD as well as the backup content, Copy0，Copy1，or Composition method.

②Module Batch Write

As shown above，it will appear this interface when you click “Function” button, and then the list box doesn’t display any file. We need to select the folder with module, click “Browse” button; it will appear the Select Folder Dialog Box:

When we have selected the file path that has already been backed up, there is content in the list box：

At this moment，we can select any files need to written into and use what kind of way to write into HDD, when you choose to use by track or by ABA to write into, please pay attention to which backup needs to be written into.

③Search SA Module and Save it

This function is one of the most characteristic function among MRT Western Digital Professional Repair Tool, open this function, it will appear the following interface：

This dialog box looks like complex but it is simple. We look down from the top：

1） After selecting the research to module, save the file as the folder path.

2） Search Range：1. The starting address of searching（We know there are two way to express address, in fact this also provides one useful tool: the switch between ABA address and CHS address. When we click “OK” button to search, please click “Switch” button to make sure the consistency between ABA address and CHS address. Of course, the program will remind us）2. Search the length.

3） Modules need to be searched, “All the modules” and “Specified modules”，when we select the specified modules, we can also input name of modules, pay attention , it is 16 Hex Editor.

4） Search method，why we need to fill in ABA address and CHS address, in fact it can provide two way of searching here.

How about, it is quietly simple, isn’t it? ^_^

5. Track Object Operation

①Track batch backup

Do you see it, here also reflects one feature of MRT, when it pops up on the screen, we will by default for you to check track with module data and ignore such track with no content of module data, and save your valuable time. The interface is simple; you know how to use at the first sight.

②Write into Track

The same as writing into module firstly select the file path with the track, the list box lists track file list, check track files need to be written into and check these files to be written into which heads, and then begin to write into. Attention, after the completion of selection, their meaning is to write files checked by you into the head checked by you！Therefore，if we want to restore the original backup, we need firstly to check file with number 0 header, and then check 0 head (only write into number0 head)！Open this function after the completion of writing into, and check the 1st header files, check the 1st head, just write into the 1st head！Like this, it can restore your original backup of track file.

For convenience, we set up two check buttons on the side, check“File On head 0”,number 0 header in the list box will be checked！Effect is as follows：
