一、The Newly-built and Open Tasks

Data Explorer Main Interface

Functional Specifications：

1、Toolbar buttons from left to right successively contains the power switch, the newly-built task, open the task and exit task.

2、Below the status light from left to right successively contains the power status lights, the device status lights and the error status lights.

New Task Guide

（一）Select Task list

Functional Specifications：

1、The default of task name is a character string generated in the current time, it is a suggestion to change the name related to the task so that it easy to remember, such as “Nanjing Western Digital ATAO 500G”. Pay attention to that task name can’t contain special characters.

2、The default of task directory is the Data Explorer directory created by the main MRT program UserDataFile folder, it can be changed by clicking the Browse button.

（二）Select the Source Device

Functional Specifications：

1、Devices in the MRT can be divided into four types, namely:

① MRT DISK： Hooking disk devices on the MRT card，namely MRT ATA0 and MRT ATA1

② SYS DISK：Hooking the HDD on the host system，including USB device and the Win7 virtual disks and so on.

③ MRT IMAGE：a collection of multiple file image stored on the disk.

④ FILE IMAGE：a separate file image stored on the disk.

2、When the mouse clicks the MRT IMAGE or FILE IMAGE, a dialog will pop up to select the source FILE path.

3、When check the “display of used device ”, displays all detected device, otherwise only displays the current unused device.

（三）The Initialization Settings

Function Specifications：

1、Running factory program：Check whether the port of the source device has been running to the corresponding factory program.

2、Soft Reset：A soft reset operation on the source equipment in the process of initialization tasks.

3、Hard Reset：A hard reset operation on the source equipment in the process of initialization tasks.

4、Read device information：In the process of initialization tasks to send commands to the source equipment for acquiring equipment capacity, serial number and other information.

5、Initialization device parameters: In the process of initialization tasks to send commands to the source equipment for getting default parameter of the initialization device.

6、Wait for the device ready time：wait for device ready timeout in the process of initialization tasks.

Attention：

1、Only when the source device is MRT DISK, there is the initialization setting.

2、If the option of soft reset or hard reset option is selected, in the process of initialization tasks it will send commands to the source device, regardless of whether the source device status is normal. The reason is that although some of the hard disks show normal state, but not work properly. The data can be read after performing soft reset or hard reset.

3、For some of the older, the not very good heads’ and ready slow hard disks, it is recommended not to check soft reset and hard reset in order to avoid the failure of initialization tasks caused by the long busy equipment.

4、For the damaged translator , or the heat exchange of the hard disk, be sure not to check the hard reset option.

（四）Task Options

Functional Specifications：

1、If you check “carrying on data copy”, after the initialization tasks, it will enter the interface of data copy, otherwise it will directly go into the interface of file browser , and unable to image the source device for related operation.

2、“Creating virtual translator ”function is temporarily undeveloped, selected or not having no influence on the tasks.

（五）Select the Target Device

Functional Specifications：

1、Only when carrying on the data copy , it will have such kind of setting.

2、When selected in different types of target devices, it will have the following additional options：

① MRT DISK：No additional options

② SYS DISK：Modify MBR

③ MRT IMAGE: Image to the task list, unit file size

④ FILE IMAGE: Image to the task list

3、Modify the MBR：Reading the MBR sector data (number 0 sector) to detect and modify the last 2 bytes (0x55AA), but not true to modify the source device data.

4、Image to the task list： Saving the image file to the task directory folder, otherwise asked to choose another save directory.

5、Unit file size：MRT IMAGE image files size of the unit, recommended 64MB.

（六）Task Information

Functional Specifications：

Display task options and settings information.

Open Task

Functional Specifications：

Located in task list，the task format is task file，.task.bak is the backup of task files, select any one of them, and then open it.

二、Data Copy Task

Data Copy Interface

$说明: D:\zty\System\桌面\QQ Photo20140116135411.jpg$

Functional Specifications：

1、The above is the toolbar of data copy task, providing view task information and control data copy.

2、The left side is a shortcut toolbar, providing the control of source device and the quick setting of task parameters.

3、The below is the data display window providing the real-time display in the process of data copy.

Task Parameter Settings

（一）Data Copy

Functional Specifications：

1、Start LBA：The starting LBA address of the copying task

2、End LBA：The ending LBA address of the copying task

3、Conversion：Providing the conversion calculation between the value of LBA and GB

4、MAX：Setting the maximum LBA to the end of LBA of source device

5、Read block size: The maximum number of sectors to be read each time when carrying on data copy, to a maximum of 256.

Under normal circumstances, the greater the value, the faster the copy speed, but when the head performance is not good or some problems existing in hard disk, the copy speed will decrease.

Besides，some series of hard disks, such as Hitachi hard disk, if the translator suddenly breakdown in the process of data copy, you can try to set the read block to 1, which can greatly avoid such circumstances of the damage of the translator and we can find the copy speed is slightly faster than set to256.

6、Waiting time for switching the MAP window: After waiting for a specified time, the program will automatically switch the MAP window to the log window, if set to 0, it does not work.

The bitmap drawing of MAP window will take up some certain CPU resources, which has a certain degree of influence on the copy speed in some poor computer configurations.

7、Automatically save the task interval: Every specified time will automatically save a task.

8、Modify the MBR: Read the MBR sector data (number 0 sector) to detect and modify the last 2 bytes (0x55AA), but it is not real to modify the source device data.

9、Reserve Copy: When carrying on data copy, it is from the end of the LBA address to begin to reverse copy data until the starting LBA address

Under normal circumstances, the reverse copy speed is slower than the forward. This is determined by the working principle of hard disk.

10、Skip read timeout sector: In the process of data copy, when read sector is timeout （red block）, it will automatically skip a specified number of sectors and then proceed to copy.

11、Skip read error sector：In the process of data copy，when reading a sector fails（black block），it will automatically skip a specified number of sectors and then proceed to copy

12、Quick Copy: In the process of data copy, ignore and skip any block which read failure.

When the state of head is very poor but needs to extract data as much as possible, we suggest using the separate copy function to enable this setting.

13、Boot feature support of the 4k hard disk：In the process of data copy，if read sector turns out to be unsuccessful, it will automatically complete the rest of sectors according to a multiple of 8 and then skip them.

This function can greatly reduce unnecessary read and alleviate the burden of the head. The reason is that a 4K physical disk storage unit corresponding to the eight logical sectors, read statue of the 8 sectors is consistent, a sector read failure, and the rest 7sectors must be read failure.

14、4K hard disk detection: Detect whether the source equipment is 4K hard disk.

15、Read failure of sector data will be filled to the target device : If enabled, after fail to read sector, it will be filled 0 or “bad！”Characters to a corresponding sector of the target device, otherwise it will not write any data to the target device.

16、Read sectors after failing N times, it will stop the task：In the process of data copy, when the number of sectors read failure has reached the specified number of times, it will automatically stop copy task.

（二）Transmission Mode.

Functional Specifications：

1、At present, there are below 7 kinds of transmission mode：

① STAT high speed transmission mode

② UDMA66 transmission mode

③ UDMA33 transmission mode

④ PIO transmission mode（with hardware entry）

⑤ PIO transmission mode（without hardware entry）：This method can be used for hard disk unreadable by PIO transmission mode（with hardware entry）, but cannot be used with a capacity of more than 128GB hard disk.

⑥ PIO transmission mode（Ignore the CRC checksum cycle）:This method can be used for hard disk unreadable by PIO transmission mode（with hardware entry） and PIO transmission mode（without hardware entry），but cannot guarantee the accuracy of data，and cannot be used with a capacity of more than 128GB hard disk.

⑦ Use the factory program to read. Under this method, it will use the factory program to read.

2、On newer hard drives, even set to UDMA33 or UDMA66 transmission mode, the hard disk will still transmit by the highest reading speed. Therefore, after changing the transmission mode, the speed of the hard drive may not change.

（三）Scan Type

Functional Specifications：

1、Type Description：

Read success

Read success，Error lights lit up after the completion of reading, and cannot guarantee the accuracy of the data.

PIO read data successfully under the condition of ignoring CRC cycle checksum transmission mode, but cannot guarantee the accuracy of the data.

Read failure

Read timeout

Skip

Data modified

Data read successfully, but written to the target device failed

Unread

2、When carrying on copies of data, it will only copy the selected bitmap type.

This setting is generally used for the segmented copy, copy completion or coordination with tasks plan.

（四）Power Management

Functional Specifications:

1、Reset the power off time：When resetting the power, the program firstly cut the power supply and wait for a specified time before turning on the power.

2、When the hard disk can not ready ,turn off the power and stop all tasks：When the performance of hard disk head is not good, it is easy to knock head, we recommended to enable this option and avoid continuous knock on the head, which causes the damage of disk after the long and busy operation of hard disk.

（五）Error Handling

Functional Specifications：

1、Number of retries after read error：In the process of data copy, when read sectors fail, it will attempt to re-read the specified number directed by sectors until it reads successfully. The performance of the head is not good or there are more bad sectors, we recommend setting to zero.

2、Skip sectors after read error ：In the process of data copy，when read sectors fail it will skip the specified number of sectors, and then proceed to copy. It is a suggestion for users to set a larger number of skipping properly. When the bad sectors of hard disk are more, it is recommended to skip a few larger several appropriate settings.

If the data copy setting is not enabled "skip read error sector" or the skip is disabled in quick settings toolbar, the setting does not work.

3、The operation after reading errors：In the process of data copy，when read sectors fail， it will in turn operate the selected source device until the device is ready for operation. Once the device is ready, the subsequent selected operation will not be executed.

For example, select the soft reset, hard reset, reset power，after reading failure, the program will carry on a soft reset operation to the source device . If at this time the device is ready, then hard reset and reset power operation will not be executed, otherwise it will continue to carry on the hard reset operation, and so on.

If not forbidden read down, and do forbidden skip, or skip number is not 1，after reading sector fails, it will begin to reverse read from the skipped sectors until the skip area is all read or read is not successful, then from the skipped position to proceed to copy.

Be sure not to check the hard reset and interrupt power options for the damaged translator or heat exchange hard disk.

（六）Timeout settings

Functional Specifications：

1、Skip sectors after reading timeout：In the process of data copy，when read sectors is overtime, it will skip the specified number of sectors, and then proceed to copy. When the statue of hard disk is not good, it is recommended to skip a few larger several appropriate settings.

If the data copy setting is not enabled "skip read overtime sector" or the skip is forbidden in quick settings toolbar, the setting does not work.

2、Timeout setting：Caused by the bad status of hard disk, some block read sector may take a longer period of time. According to transmission mode, the waiting time of PIO read mode and UDMA read mode can be set longer properly.

Attention，when ready slow problems exists inside hard disk, the waiting time needs to be set longer after resetting the power. Some hard disks with bad status after power off always wait for a few minutes or even more time to be ready.

3、The operation after reading timeout：In the process of data copy，when read sectors overtime，it will in turn operate the selected source device until the device is ready for operation. Once the device is ready, the subsequent selected operation will not be executed.

For example, select the soft reset, hard reset, reset power，after reading timeout, the program will carry on a soft reset operation to the source device . If at this time the device is ready, then hard reset and reset power operation will not be executed, otherwise it will continue to carry on the hard reset operation, and so on.

If not forbidden read down, and do not forbidden skip，Or skip number is not 1，after timeout of reading sector , it will begin to reverse read from the skipped sectors until the skip area is all read or read is not successful, then from the skipped position to proceed to copy.

Be sure not to check the hard reset and interrupt power options for the damaged translator or heat exchange hard disk.

（七）Head bitmap

After input head bitmap LBA address range which needed to created, click OK, it will appear the following progress window:

After creating the head bitmap, it will display the case of source device head,

As shown below,

2、Separate copy: In the process of data copy, it will only copy the selected heads. When the performance of head is not good or a head with some problems, it is strongly recommended to use the separate copy and then boot separate copy skip strategy.

Further coordination with task plan setting, and automatically carries on copy tasks for many times. Every task adopts different strategies according to different heads.

（八）DRQ Setting
