Log Page Startup Information Description

The information displayed in Scan Disk tools at the startup of the hard disk reflects the current basic statue of the hard disk, such as: whether to set the password, whether to support LBA setting, whether to read…For more details of circumstance, please click Function——Device IDto have a checkLog Page Startup Information has respectively the following several circumstances

2.1 Normal Circumstance

At this time it indicates that the hard disk can set maximum LBA (for more information about setting maximum LBA, please refer to Chapter III); turn on SMART function; open cache writes:

At this time it indicates that the hard disk does not support the maximum LBA setting, other information ditto.

2.2Abnormal Circumstances

       At this time it indicates that the read is wrong,, users should check the status of each register on the status bar, if everything is normal users can click the “Refresh” button to re-read, or still displays the information, it may be due to the damage of the hard disk firmware leads to the program unable to read the hard disk information.

This moment it indicates that the hard disk has set the password, other functions are normal.

This moment it indicates that the hard disk has set the maximum LBA, and displays the current LBA and original LBA.

 

 

 

 

 

Function Menu

The function menu of Scan Disk program provides "Scan", "View SMART", "Device ID" and other common functions, menu structure as shown in Figure 3.  

3.1 Scanning

   Scanning provides the test to the basic statue of hard disk, for example scan the entire disk, bad sector test…

       It will pop up the Scan Settings dialog box before the start of scanningAs shown in figure3.1-1),asks users to set the starting point and the end point of scanning.

                     Figure3.1-1 Scanning Setting

After setting the scanning information, click “OK” button to begin to scan.As shown in figure3.1-2

                                          Figure 3.1-2 Scan Status

The scanning result indicates that green blocks represent normal sector, yellow and pink blocks represent that this sector can be read in the specified time, dark red blocks represent the sector can’t be read in the specified timeprobably because the timeout is set too short),light red blocks represent the hard disk reports an error while reading this sector

3.2 SMART

       Self monitoring, Analysis and Reporting Technology (SMART) (As shown in figure3.2-1) are designed to protect users’ data and reduce the possibility of sudden system downtime caused by the expected degradation or the malfunction. By monitoring and storing critical performance and standards parameters, SMART device attempts to predict the time close to the condition of degradation and malfunction. If the host system knows a non-reliable condition, it will allow users to take appropriate measures.

                      Figure 3.2-1 SMART

    Attribute is used to analyze the statue of the device with specific performance or standard parameters. Attribute is based on some attribute by device manufacturers for those special devices to forecast the contribution ability of degradation or malfunction condition and then make a choice. The used special settings and the identity of attribute are specific and proprietary for the suppliers.

Attribute value is used to describe the associated with individual performance or the reliability of standardized attribute. The valid range of attribute value is from 1 to 253. The high attribute value indicates that analysis and calculation is used by the device to forecast the less frequent degradation or the possibility of malfunction condition existing. Thereforethe low attribute value indicates that the analysis and calculation is used by the device to forecast the frequent degradation or the possibility of malfunction condition existing. 

Every attribute value has the corresponding attribute ultimate limit, which limits to use direct comparison attribute value indicating that degradation or malfunction condition exists. Attribute limit value is determined by the device manufacturers according to the design and the analysis of the reliable experiment. Ultimate Limit indicates that its corresponding attribute value still remains the positive reliability statue, equal to the lowest limit. The ultimate attribute limit can be set in the factory of the device manufacturers and can’t be changed in the process of use. The valid range of the ultimate limit is from 1to 253.

If one or more attribute value is less or equal to their corresponding ultimate limit, so the reliability statue of device is close to degradation or malfunction condition.

3.3 Device ID

       To recognize the detailed information of device, including hard disk model, serial number, capacity, and whether to set the password as well as hard disk supports what functions, whether to start the function.As shown in figure3.3-1.

3.4 Set the Maximum LBA

   Setting the maximum LBA (As shown in figure 3.4-1) can be cut on the hard disk, used in 48-bit mode and the 28–bit mode48-bit mode maximum addressing up to 0x0H0xFFFFFFFFFFFFH28-bit mode maximum addressing up to 0x0H0xFFFFFFFH. It can be written in RAM or SA service area, written in RAM service area is only valid for this setting, it will recover after the power off, written in SA service area is valid permanently.

  

                   Figure 3.4-1Set the Maximum LBA

    After setting the maximum LBA, click“OK”button, it will instantly take effect, if the setting turns out a success, it will display the following information in the log page:

Set Max LBA Succeed...............................................117210239ll

Otherwise it will display

Set Max LBA...........................................................Error

At this time click“Refresh”button, the change of hard disk capacity will be seen in the information bar.

3.5 Security Subsystem

       Security Subsystem can carry on the security settings on the hard diskincluding freezing the hard disk, adding the host password and user password, erasing the password, erasing data

3.5.1 Freeze the Hard Disk

  After the success of freezing the hard disk ,it will display the following information in the log page

HDD Frozen............................................................:OK

It indicates freezing the hard disk turns out a success.

 HDD Frozen............................................................Error It indicates freezing the hard disk turns out a failure, probably because the hard disk is set the password or it fails to send the command.

3.5.2 Set the Password

    Users can set the host password and the user password,  As shown in figure3.5-1When the level of user password is high, the host password can clear the user password;  When the level of the user is the highest, the host password can’t clear the user password.

              Figure3.5-1Set the Password

After the success of setting password, it will display the following information in the log page

Setting security password is successful. Password type: user password. Main password capability level: High:

It indicates setting the password is successful. Otherwise it will display the following information, indicating that it fails to set the password.

Security password settings............................................Error

3.5.3 Unlock or Cancel the Password

       When users need to unlock or clear the password, users can firstly click the corresponding type of password needs to be unlocked or to be cleared, and then input the correct password.  Click Temporary Unlock button, it is only valid in this operation, the hard disk still  needs  encryption after the power off; Click "permanent abolition of password" to clear the password permanently.

If at this time users lost the user password and the level of password is high, users can use the host password to unlock the user password. Users only need to click "User Password" option in the password type column, and then input the correct host password in the password data Or import from the file, finally click "Temporary unlock" or "permanent elimination of password" to clear the user password,( as shown in figure 3.5-2).

                  3.5-2Unlock or Cancel the Password

3.5.4 Erase hard drive data

  Under the circumstance that without knowing the user password or the level of the user password is the highest, the host password can be used to erase all the data of users, and then the user password will also be erased, data will not recovery after erasing, as shown in figure 3.5-3.
