Detailed Description of Drum-Plate Embodiments In the following detailed description, only the preferred embodiments of the invention are shown and described, and only by the description of the best mode of thinking of the inventor (etc.) implementing the invention. As will be realized, the present invention can be amended on various obvious levels without departing from the invention. 5. Invention Description (6). Accordingly, the drawings and descriptions are to be regarded as illustrative in nature, and not as restrictive. FIG. 1 is a flowchart of a method for recovering a disconnection slot in a hard disk according to a first preferred embodiment of the present invention. As shown in Figure 1, the sector information is read from a damaged hard disk drive in step S110. The sector information has divisional block distinguishing information. In detail, the magnetic zone > has the information needed to divide a machine into many different divided blocks. Generally, a disc of a FAT file system includes a boot sector, a first FAT, a second FAT, a directory entry point, and files. A detailed description on the FAT file system can be obtained from the 'Advanced MS DOS Program' published by Microsoft in 1986 and 1998 and written by Dukane. For example, 'if the FAT file system described below includes a partition block table, a boot sector, a FAT, a directory, and data sector information 0 i cut block f boot sector FAT root directory data Generally, the partition The block table has information on a starting position and the size of each body when a physical hard disk has been divided into one or more logical bodies. For example, in the case of partitioning a 4-gigabyte hard disk into two logical bodies of 2 gigabytes each in size, the partition block table has the first logical body occupying from 0 to 2 on the hard disk. One gigabyte position and the second logical body occupying information from 2 to 4 gigabytes (please refer to the following structure PARTITION_TABLE). The boot sector is set on the first sector of each of the divided blocks and has information on the classification of the file system, the size of the fat, the number of the entire sector, the location of a starting cluster, and the number of sectors (please Refer to the following structure 548542 (7) V. Description of the invention A-BF_BPB = BIOS parameter block). F A T detects the location of a cluster of links between the configuration file and the storage cluster. The root directory 'is the most local directory of the slot or directory, and stores the directory structure, 5 first name, starting sector, file size, sub-directory information, and body logo. When the root directory is damaged, the files cannot be found by a normal operating system. When using the Norton supplies disk editor program (diskedit.exe) on such a FAT file system, the hexadecimal codes and data can be dumped to be stored as a file or they can be printed out. 0 Hereinafter, the structure of the BIOS parameter block (bpb) of the divided block table will be described. When partitioning a logical hard disk. In detail, the partition block table // 0x80-act ive // Starting head // Starting sector // Starting cylinder // What partition type // End head // End sector // End cylinder When a hard disk is divided into one or The data on the configuration of more tables with each partition block has the following contents: Structure PARTITION_TABLE {BYTE Part—Bootlnd; BYTE Part—FirstHead; BYTE Part—FirstSector; BYTE Part—FirstTrack; BYTE Part_FileSystem; BYTE Part_LastHead; BYTE Part—LastSector ; BYTE Part—LastTrack; DWORD Part ^ StartSector; // Starting magnetic count from zero -10- 20 54 mr / ry ™ ------ year Η — day 8 ¥ to correct * 4.-· ^ ； V.

Referring to FIG. 1 again, the FAT information is read from the hard disk drive in the previous step si 10 and the root directory information is read in steps S115 and S120. The data sector is analyzed and the damaged directory information is searched for in step S125, and a searcher interface is used to recover the searched directory in step S130. As shown in Figure 2, the magnetic field viewer of the data and directory is displayed on the screen in step 3135. Fig. 2 shows a display screen of a magnetic field editor according to a first preferred embodiment of the present invention.

The editor screen of the sector viewer for data and directories when switched to hexadecimal on the screen. A user can then check from the data or directory sector in the previous one as shown in Fig. 2 to check that the month 1J-step S135 is disconnected in step S140. Whether the cluster is shown by checking in the sector editor

The user can display the magnetic disk of the hard disk as shown in Figure 2 to check the fragmented data code. At the same time, the data is 25mm%. 5. Description of the invention (10) When it is determined that the cluster is edited in the magnetic zone displayed in the previous step S140 When the monitor screen is disconnected, the user manually drags and drops the fat editor in step 8145 to edit the information on the disconnected link. At this time, the fat editor automatically and directly edits the configuration values of individual clusters, and can also edit the physical sector, 5 logical sectors, or clusters. At the same time, a trade-off right for displaying a data in a specific pattern to store a predetermined area of a magnetic region or cluster according to a format may also be added. Figure 3 shows a glorious display showing the entire fat and one of the fat files and directories. Refer to Figure 3 for details. When transmitting the zone editor message to the user, the cluster can be displayed directly. For example, clusters corresponding to a file are displayed in different colors, while other clusters corresponding to a displayed file can be configured, and the rest can be manually edited. After storing the files, when they are found to be normal, the slot value 15 is stored in FAT1 or FAT2, or both FAT1 and FAT2. A menu to select the next cluster from the current cluster by clicking a mouse can also be added. At this time, the next cluster can be selected from the FAT table or the sector editor. Make a new Clipboard format to implement this feature. That is, when the user presses a 'boot to select the next, FAT button, a piece of paper is implemented through the clip board and the -0 viewpan message to determine whether the mouse pointer controller will be controlled by the overall variable. The restored FAT information is stored in the memory in step S150, and the restored data is stored in the hard disks of other units in step S155. At this time, it is obvious that the capacity of the hard disks of other bodies must be equal to or larger than the capacity recovered from the damaged hard disk of the invention description (11). As mentioned above, when there is an initial recovery data for a general data recovery method, such as when using DOS or Norton supplies to recover and delete programs, when a user deletes data, a FAT value is configured and the FAT value is written on the hard disk. And therefore shell material may be lost. However, in the present invention, the FAT information is processed in the memory, and after the data is recovered and checked to determine whether the recovered data is suspended, the FAT is instructed to be configured. As a result, data is processed in a way safer than conventional technology, and the rate of data recovery has increased significantly. In order to maintain the memory-managed information when the computer is restarted, the function of storing or loading FAT information as a file is added. here

In the If form, the FAT information is not stored on the damaged hard disk, but on the hard disk of another secure body. Generally, when a user misuses a computer or when data stored on a hard drive is damaged due to an error on some computer's own hardware, the information recorded in the data system of the hard drive or login file also changes . Therefore, by comparing this: Beizun with the initial state of the data system and the login file, the difference found can indicate that the part of the hard disk drive where the difference occurred is damaged. Fig. 4 is a flowchart of a method for recovering data from information on a damaged directory itself containing corrupted data according to a second preferred embodiment of the present invention. As shown in FIG. 4, in step S21O, the read function from a magnetic sector reads out the damaged hard disk drive or detects the magnetic sector information. The value of the boot sector is measured in step S215, and the disc information is analyzed based on the value of the boot sector in step S22. At this time, Magnetic V. Invention Description (l2 10 > 0 generally contains data system information for one body. For example, FAT16, FAT32, and NT (Windows NT) File System (NTFS) have boot sectors with different information. As an example, the structure of the BPB of the boot sector used in FAT32 is as follows: typedef struct_A—BF—BPB {// FAT BIOS parameter block WORD A_BF_BPB_BytesPerSector; // Number of bytes per sector BYTE A—BF_BPB_SectorPerCluster; // Number of magnetic sectors per cluster WORD A_BF_BPB_ReservedSectors; // Reserved magnetic sectors BYTE A_BF_BPB_NumberOfFATs; // Number of FAT WORD A_BF_BPB_RootEntries; // Maximum number of root directory tables // Magnetic zone size of divided blocks BYTE A_BF_BPB_MediaDescriptor; // Media description WORD A—BF—BPB_SectorsPerFAT; // Number of sectors per FAT WORD A_BF_BPB_SectorsPerTrack; // Number of sectors per track WORD A—BF_BPB—Heads; //-Number of R / W heads of the unit WORD A_BF_BPB_HiddenSectors; // NUMBER A_BF_BPB_TotalSrctors; -15-

When it is a FAT file system, in step -16- 548542 V. Invention description (l4) The data in S240 is restored by the FAT file system. Fig. 5 is a flowchart of a method for recovering data in step S240 shown in Fig. 4. Please refer to FIG. 5. The FAT information of the hard disk is detected and then stored in the memory in step 5 S610, and the root directory information is detected and then stored in the memory in step S620. In the case where the data sector does not have directory information but only data, the data sector is analyzed according to the data type, and the damaged directory is detected in step S630. 10 By using the information obtained in the previous steps S610 to S630, the directory information to be restored is analyzed, and the analyzed directory information is used to generate a directory in step S640. The damaged directory is restored, and the damaged data stored in the restored directory in step S650 is restored. [5 Figure 6 is a flowchart that provides a detailed explanation of the steps for restoring directories and data shown in Figure 5. Referring to FIG. 6, the initial size of the data manually found in a setting environment is changed to an arbitrary size in step S6510. The data found according to the file's extension is registered in step S652. 0 is on a directory recovery screen, and the information on the data name and size is analyzed and generated in step S6530. When necessary, the user manually and arbitrarily corrects the data name and its size in the list on the directory recovery screen in step S6540. The required information is stored in step S6550 in a different unit from the first unit -17- 5. Invention description (15) A second unit. At this time, the second body must have a storage capacity equal to or larger than that of the hard disk of the first body. The size of the recovered data initially stored in the previous step S6550 is compared with the person who damaged the data in step S6560, and if the size of the corrupted data is larger than the person who recovered the data, the procedure returns to the previous step% 54 to reconfigure the data Name and size. If the size of the corrupted data is smaller than that of the recovered data, a program for recovering the recovered material is used to read the recovered data in a normal manner. Above, the present invention recovers damaged data so that when a user deletes a directory and the information on the deleted directory is lost, the data stored in the hard disk can be recovered. Fig. 7 is a structural diagram of a remote control data recovery system according to a third preferred embodiment of the present invention.
