Description

Data protection and restoration device in a hard disk for a computer {APPARATUS FOR PROTECTING AND RECOVERING DATA IN HARD DISK FOR COMPUTER}

The present invention relates to a data protection and restoration device in a computer hard disk. In particular, system software, application software, or system administrator's data in a computer hard disk are protected from any artificial or natural damage, and users delete files artificially. In the event of a catastrophic damage to the hard disk due to disk formatting or virus infection, only one restart of the computer restores the damaged data back to its original state, and even if the CMOS setup data is damaged. The present invention relates to a data protection and restoration device of a hard disk for a computer, which allows a hard disk to be protected and restored.

In general, a computer hard disk includes system programs, applications, and various system management materials. Such system software, application software, or system management data in the computer hard disk may be damaged by any artificial or natural damage, or It can be fatally damaged by undesired file deletion, disk format or virus infection by user. Accordingly, there is a need for a technique for protecting and restoring data on a computer hard disk.

As described above, in the conventional method of protecting the data of the hard disk in the computer, when the data in the hard disk is damaged, the hard disk utility software in the operating system checks and inspects the hard disk and displays the result of abnormality. Utility software (Norton Disk Utility, etc.) is used to recover some of the damaged data.

However, the conventional recovery method using utility software such as Norton Disk Utility can recover deleted files, but it can't recover them completely, but there is a limit to implementing them by software alone. It does not repair or restore any fatal causes such as virus or virus infection.

In addition, it is impossible to completely recover from such catastrophic damage, and even with some recovery, the hard disk must be reformatted and system data must be reinstalled. These operations are very time consuming (usually 2 to 4 hours). There are many and cumbersome tasks.

In addition, the conventional software hard disk recovery method can determine the degree of damage to the hard disk, but it is impossible to repair or restore the hard disk, and moreover, when the system data is damaged due to a disk format or a virus infection, the computer system Since the hard disk utility software cannot be operated because it itself becomes inoperable, some recovery functions cannot be performed. The recovery function of the conventional method as described above is limited to only a few parts, and the original recovery function is impossible at all. There was a problem.

The present invention has been made to solve the above problems, and therefore, the object of the present invention is to protect system software, application software, or system management data, etc., in a computer hard disk from any artificial or natural damage, and to prevent users from artificial When the hard disk is damaged due to file deletion or disk format or virus infection, only one restart of the computer restores the damaged data to its original state, and furthermore, the CMOS setup data is not damaged. The present invention provides a device for protecting and restoring data on a hard disk for a computer, which protects and restores a hard disk that is restored to its original state.

The data protection and restoration device of the hard disk for a computer obtains the control right of the basic hard disk input / output (BIOS) of the computer and controls the hard disk protection area set in the application software in advance to protect the data in the hard disk from accidental damage. It restores data safely by moving the data stored in the area to the operation area, and also stores the computer hardware configuration data in the CMOS setup of the computer in the protected area of the hard disk. Even if this material is damaged naturally or artificially, Let emitter restart during the reading of the material damage during storage, check the damage of materials characterized by recovering the data securely.

In other words, it intercepts the hard disk control function of the computer's basic input / output system (ROM BIOS) and independently controls the hard disk to implement the hard disk restoration function. Save the data in the safe storage area (Backup area), and if the data in the hard disk active area is found to be damaged, take out the data in the safe storage area of the part and replenish the damaged area in the active area to restore the damaged part, and computer environment setting data. It performs a function of restoring when the CMOS setup data is damaged.

In addition, the read-only memory device 1 intercepts the read / write stop signal INT 13H to write data to the mirror disk set as a specific area of the hard disk at the time of writing the data, and at the time of reading, the state of the mirror disk. It includes a restore program that reads the data on the mirror disk if there is data on the mirror disk, and reads the data on the logical disk if there is no data on the mirror disk. do.

Such a data protection and restoration device of a hard disk for a computer of the present invention is a hardware that can be easily inserted into a computer's main board, and is manufactured as a card type for controlling a hard disk, and includes application software for managing such hardware. have. Therefore, the present invention can be applied to the computer hard disk protection and restoration device in the computer training lab of each school and academy.

The device of the present invention stores the data in the hard disk in the safe storage area set by the application software while controlling the hard disk accurately, and in case of any damage to the data in the hard disk, the control card is restarted by restarting the computer. The original data is recovered by checking whether there is an abnormality in the active area of the actual data and by registering the data stored in the safety storage area in the active area when an abnormality is found.

According to the device of the present invention, there is no need to worry about how the data in the hard disk is damaged and how the contents of the computer's configuration data (CMOS Setup data) are changed and is automatically restored to the original state when the computer is rebooted.

The protection and restoration card of the present invention includes separate memory devices such as read-only memory device 1 and read-write memory device 2 as described above, and has a computer-based basic input / output system (ROM-BIOS). It can secure functions, controlling boot interruption and disk read / write interruption. And set the space to store main program or special data in specific area of hard disk.

The hard disk control card of the present invention directly controls the read and write on the hard disk to execute the program of the protected area and obtain a reference material thereof. It also drives several drives at once, automatically updates the first partition on the hard disk, displays the data on a specific area of the hard disk, and simultaneously has multiple boot systems. Accordingly, upon restarting, the original data of the hard disk can be automatically restored, and the original computer computer setup data (CMOS Setup data) can be automatically restored.

FIG. 2 is a flowchart illustrating a booting operation of the protection and restoration device of FIG. 1, FIG. 3 is a diagram illustrating a multi-boot operation of the protection and restoration device of FIG. 1, and FIG. 4 is a hard disk of the protection and restoration device of FIG. 1 immediately. A recovery operation flow chart. 5 is a flowchart of an update operation of the restoration apparatus of FIG.

Operation according to the device of the present invention configured as described above will be described in detail below based on the accompanying drawings.

First, referring to FIGS. 1 and 2, the operation process during booting by the device of the present invention will be described. FIG. 2 shows the internal operation of the hard disk protection restoration card after power on (step 201) or reset start (step 202). First, after this booting, the basic input / output system (ROM-BIOS) of the computer starts a diagnosis (step 203) regarding all hardware related to the computer and performs initialization of the computer hardware after the diagnosis is completed. The system BIOS then checks to see if there are any reserved BIOSes in the computer system (e.g., SCSI-ROM, specific card-ROM, network-ROM BIOS, etc.) (step 203). .

Then, the computer system confirms that the hard disk protection restoration card of the present invention exists (step 204). In addition, after confirming that the hard disk protection restoration card of the present invention is suitable for securing the hard disk control function from the computer's basic input / output system (ROM-BIOS), the system obtains the execution authority related to hardware from the computer system (step 205). ). The restoration card then disconnects the INT 19H (computer system boot interrupt signal) from the basic input / output system (ROM-BIOS) and secures the authority to use the INT 19H signal from the system BIOS (step 206). After executing all the reserved BIOSes detected inside the computer, the restoration card BIOS stops generating the INT 19H signal (step 209), and the restoration card immediately reads the read-only memory device (1). Run the internal program of the computer and check whether the application for restoring the hard disk is installed (step 211). If not, run the installation program and re-run the computer system to repeat the above operations (steps 216 and 217). Then, it is judged whether the restoration application is installed, and if so, the restoration application in the restoration card read-only memory device 1 is executed (step 212).

Referring to Figure 5 in more detail the application program update process by the restoration device of the present invention, first through the execution process of the system (BIOS) (steps 501,502) and then the program in the restore card read-only memory device (1) Is executed to read data in the hard disk storage area (Backup area), and then it is judged whether or not a restoration application exists (step 503), and if the application does not exist, the user is asked to insert an application installation diskette. In step 506, the application program is installed in the hard disk protection area (step 507), and the system is restarted (step 509). If it is confirmed that the application has already been installed, it displays the message that it has been installed immediately and the application runs, with the option to ask if there is an upgraded version of the application (step 504). If there is a copy, the card can be updated quickly through the above process (step 508).

Then, referring to Figure 2 continues to describe the operation of the restoration device of the present invention, when the computer is started in the situation that the restoration card application is already installed, the application is executed first multi-boot (DOS, WINDOWS-95, OS2, WINDOWS NT, etc.) a selection screen will appear (step 212). This provides a choice of which operating system the user will start up, and when the user selects which operating system to start up, the application on the restore card will automatically update the partition data on the hard disk (step 213), The restoration card enters the BIOS INT 19H and the BIOS system task startup (steps 214, 215), thereby completing the flow of a series of computer boot systems.

As described above, the hard disk restoration apparatus can select and start various operating systems by using a multi-boot selection screen displayed by executing a restoration card and an application program. And operating under the selected operating system are only executables and data that operate under this operating system, and the series of operations associated with the startup is a task that is formed completely hidden from the operating system. This is also a quite different concept from the multi-boot format we generally know.

Referring to FIG. 3, the operation process of the above multiple booting is described in more detail. As shown in FIG. 3, the right side 33 of the figure is a partition area of an actual hard disk, which is one program area (MBR) and a maximum. It consists of four partition areas and ID recognition area, which means that one hard disk can hold up to four partition areas. It can be designated as four logical drives C, D, E, and F. The device of the present invention is used to store data by fixing the second, third and fourth partition tables of the hard disk. The logical drive C represented by the first partition table is one of partition data located in the hard disk area on the left (31) of the figure.

Then, under the instruction of the multi-boot selection screen 32, the partition data below is selected and the contents of the first partition table of the hard disk on the right side 33 of this drawing are updated, and the partition data of the hard disk area on the left side 31 of this figure is updated. Is selected based on the hard capacity required for each boot selection, and then, in order, the specific track range of the hard disk is used as the content of each partition. (The content of the partition data only shows information of the start track and the last track of the partition. It is only.)

For example, a DOS partition is defined as tracks 5-10, WINDOWS-95 tracks 11-20, WINDOW NT tracks 21-40, and OS2 tracks 41-80. In this way, a number of partition data is generated. In this case, when the DOS partition data is to be taken from the multi-boot selection screen 32, the corresponding partition data is taken from the area on the left side of the diagram (31). Write at the location of the first partition table in. Thus, only the contents of tracks 5-10 appear on the hard disk C drive, and the start track of the hard disk C drive starts from the fifth track and starts the DOS system.

As described above, the other track contents cannot be represented or touched, so that the other operating system is well protected and not damaged. When booting into a relatively different operating system, the same principle as described above can also be used to select different partition data in the area of the hard disk and overwrite it under the first partition table of the hard disk partition, which will have the effect of shutting down the operating system. do.

In addition, the present invention has a multi-boot function that can use a variety of operating system in one hard disk, the device of the present invention overcomes the limitation that the hard disk can have only four partitions, each operating system By completely independent of the system, it is very convenient to manage from the computer lab manager's point of view.

In particular, the above-mentioned application update function and multi-boot are additional features of the system, and the main feature of the present invention is to restore to the state originally planned when the computer is rebooted. When various changes are made, the original data is not affected.

Such a restoration function by the device of the present invention automatically restores the hard disk data, and also automatically restores the computer's CMOS setup data, and automatically restoring the CMOS setup data. The administrator of the restoration device sets up the CMOS setup data and saves the setup data in a specific location on the hard disk area.Then, when rebooting, the restore card is immediately stored in this hard disk area by hard disk I / O method. It reads the CMOS setup data and compares it with the computer's current CMOS setup data. If it is different, it immediately converts the stored CMOS setup data in the hard disk to the computer's CMOS setup data. It will overwrite the zone and reboot immediately.

Therefore, no matter how the user touches the CMOS setup data, it is automatically restored to its original state upon reboot, so that there is no need for the user to set the CMOS setup data again.

On the other hand, the restoration device of the present invention can automatically restore the data of the hard disk, there are two methods of automatic restoration of the data in the hard disk, this restoration method can be selected when installing the restoration device, One way is to restore immediately, the other way is to restore a backup.

First, the instant restore method will be described with reference to FIG. 4, since the restoring apparatus of the present invention has a function of intercepting a disk read write interrupt signal (INT 13H), even if the disk I / O operation is interrupted due to the interruption of the INT 13H signal. In addition to the logical disks set by the computer system through the predetermined processing of the corresponding mirror table and mirror disks, the respective mirror table and mirror disk are also applied to each read / write unit (1, 2, 3 ...) of the logical disk. Install and set up this mirror table in a specific storage area of the hard disk, and the mirror disk will set the hard disk area of a different capacity from the specific area of this logical disk as a mirror disk when planning. (See also the operation flow of FIG. 4). When the recovery card of the system intercepts the INT 13H signal (hard disk read / write operation) (step 41) and the interruption of the interception occurs, the recovery card first determines whether to read or write data (step 42).

If it is in the read state, the contents of the mirror table at this read position are determined as 0 or l. (Step 43) If it is 0, the process proceeds to step 44 and if the mirror table is set to 1 (read to read the data of the original logical disk). If the data of the mirror disk is already written in the mirror disk, the data of the mirror disk is already written. If the data of the mirror disk is determined to be a write operation, the process proceeds to step 46 and writes the data to be written to the mirror disk. At the same time, the corresponding mirror table is set to 1 in step 47, the operation described above is completed, and the process returns to the application program location in step 48 to continue processing.

As described in the above operation, any write operation does not change the contents of the original logical disk, and the hard disk data is securely protected so that all contents of the mirror table of the mirror disk can be deleted and rebooted by the user in a new state. . Under these programs, users can back up to a diskette when they complete various changes and modifications, and then copy the data back to the hard disk for future use.

Next, one of the methods of restoring the data in the hard disk automatically is as follows. When setting the backup restore order, make the hard disk larger than the logical disk and place it on the backup track at a specific location of the hard disk. After the planning of the logical disk is completed, the device of the present invention copies all the contents of the logical disk to the backup track, and executes a restore item of the application program at boot, and all the contents of the backup track are copied to the logical disk. Thus, if the user makes any changes or damages to the logical disk, they are restored to their original state through the restoration phase. This saves you the trouble of having to reinstall or reset your data.

As described above, the present invention is a protection restoration card that supports a hard disk system, which can intercept a boot interrupt signal (int 19h) and intercept a hard disk read / write signal (int 13h) to a specific area of the hard disk. It allows you to save the application and hard disk partition data of the restore card, restores the damaged data of the hard disk momentarily, and automatically restores the CMOS setup table. In addition, it has a multi-boot function to start various operating systems, and has the advantage of quickly upgrading an application program using a diskette. This device of the present invention solves all the problems of management and maintenance of the computer lab and automatically restores the original state upon rebooting, which combines creativity and practicality to protect and restore the most important data in the hard disk in the computer. can do.

6.Remove HDD KEEP CARD

To remove the restore card from the computer, make sure the card is inserted and then execute the "Remove card" item in the setting menu below.

You will then be asked whether you want to remove the card, press "Y" and you are ready to remove it, power off the computer and remove the card. The disk will be in the state.

The differences between the present invention and the conventional methods as described above are summarized in Table 1 below.

According to the present invention as described above, the system can be completely recovered with only one restart and can be quickly restored (usually within a few seconds). This function saves time, manpower, and cost, and is very effective for hard disk maintenance. You can cope.

In addition, the present invention consists of a protection restore card of a computer hard disk and its application software, which is mainly used for computer labs in schools, and automatically restores the original contents of the hard disk upon rebooting the computer, and automatically functions as a CMOS data. To recover.

In addition, you can have multiple boot systems on a single hard disk and use multiple drives. Therefore, it is used for computer education, and it is effective in eliminating inconveniences related to computer education instruction and hard disk data protection. Currently, a large number of computers exist in computer labs (about 40-50), As a result, inadvertent operation and inadvertent handling of the user often result in incorrect input of the CMOS configuration data, damage to the operating system and applications existing on the hard disk, and the original data being changed incorrectly. When the hard disk data is incorrectly erased or damaged due to this reason, the general maintenance method is to reinstall the program or change the relevant configuration data. In terms of maintenance and maintenance Which it was inconvenient and wasteful in terms of time and manpower and money in many ways.

Therefore, the present invention can restore the damaged data of the hard disk to its original state immediately when the computer is rebooted even if any fatal damage to the data in the hard disk occurs as described above. It has the effect of completely solving most of the most wasteful problems.

In addition, it is sometimes necessary to train several different operating systems at the same time in a computer lab, although installing different operating systems from the same hard disk can work. It works by booting.

However, in this case, the biggest problem is that even if you boot into any operating system, after operating the operating system, you may inadvertently damage the operating system or its related files that are not yet running due to user's inexperience. This can be very confusing for users and can lead to serious administrative problems in computer protection and maintenance. Therefore, if you display the file information and data related to the operating system on the screen when you run it, it will be very easy to use and very convenient for the protection and maintenance. It has the side effect of having such multiple boot.
