In accordance with an instruction from the processing units 412 ₁ and 412 ₂ , the block-unit access operation by the corresponding disk drive units 403 and 404 is controlled.

  Also, the sector write processing unit 413 of the file control unit 410 performs a sector unit writing operation by the CD-ROM writer 405 in response to an instruction from the file write processing unit 414 provided corresponding to the CD-ROM writer 405. The sector read processing unit 415 reads the sector unit by the CD-ROM reader 406 in response to an instruction from the file read processing unit 416 provided corresponding to the CD-ROM reader 406. It is the structure which controls operation | movement.

The file control unit 410 is provided with a file transfer processing unit 417. Normally, the file access processing unit described above according to an instruction from the command processing unit 418 that receives an instruction from a user or application software. 412 ₁ , 412 ₂ , the file writing processing unit 414 and the file reading processing unit 416 are configured to realize exchange of information between auxiliary storage devices such as a hard disk device and a CD-ROM drive in units of files. Yes.

In such a conventional file control unit 410, the functions of the file transfer processing unit 417, the file access processing units 412 ₁ and 412 ₂ , the file writing processing unit 414, and the file reading processing unit 416 described above are provided by the operating system. On the other hand, the functions of the block access processing units 411 ₁ and 411 ₂ , the sector write processing unit 413 and the sector read processing unit 415 are provided by a BIOS (Basic I / O System) or a device driver.

In FIG. 7, the block transfer processing unit 419 controls the access operation for each block by the block access processing units 411 ₁ and 411 ₂ in accordance with an instruction from the user, and the specified hard disk device. By copying the entire recorded contents or the recorded contents of the entire designated section and transferring and writing them directly to the recording medium of the hard disk device designated as the copy destination, copying in block units between the hard disk devices 401 and 402 is realized. Yes.

  The function of the block transfer processing unit 419 is based on the fact that the hardware conditions such as the block size and recording method are the same between hard disk devices, and is provided by utility software for maintenance work. Yes.

  Conventionally, when the recorded contents of the hard disk device are destroyed, the user brings the hard disk device to the manufacturer's service store and uses the above-described utility software to make all the hard disk devices provided in the service store. The recorded contents of the hard disk device were restored by sequentially copying the recorded contents of the block.

  It is also possible to install the operating system and application software again from a floppy (registered trademark) disk attached to the personal computer.

  In this case, the user copies the floppy disk application software etc. to the hard disk in units of files using the copy command provided by the operating system for each operating system that is running. What is necessary is just to reconstruct the recorded contents of the device.

  However, since the copy command provided by the operating system targets only the files managed by the operating system on which the command is operating, the copy command of MS-DOS, for example, is the OS-2 You cannot copy files. Also, when copying each file, it is necessary to reconstruct the directory structure of the file directory.

  As described above, when the user brings the hard disk device to the manufacturer's service store, the restoration work is performed by the maintenance worker on the manufacturer side, so the user needs to have detailed knowledge about the file system and so on. Absent. However, bringing a hard disk device to a service store has been a heavy burden on users.

  On the other hand, when the user reconstructs the recorded contents of the hard disk device from a floppy disk or the like on which software is recorded, it is not necessary to transport the hard disk device. However, the user himself / herself needs to have detailed knowledge about the hard disk device and the file system.

  On the other hand, if the user has a backup hard disk device storing the recorded contents at the time of shipment, the user himself / herself can restore the recorded contents of the hard disk device at home using the utility software described above. Is possible.

  However, in this case, in addition to the normally used hard disk device, it is necessary to have another hard disk device only for backup, which increases costs and is a waste of resources. .

An object of the present invention is to provide a recording content restoration method for an auxiliary storage device that allows a user to easily restore the recorded content of the auxiliary storage device regardless of the type of auxiliary storage device used for the restoration work. And

The recorded contents at the time of shipment can be restored to the auxiliary storage device at the restoration destination, so that the recorded contents of the hard disk device etc. equipped in the pre-installed personal computer are destroyed due to an accident. Can be easily and accurately restored. Thereby, the work burden of the user when such an accident occurs can be greatly reduced, and the serviceability for the user can be improved.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, taking as an example the case where the recorded contents of a hard disk device are restored using a CD-ROM.

  FIG. 3 shows a block diagram of an embodiment of a computer system provided with a file control unit for realizing a recorded content restoration system of a hard disk device to which the present invention is applied.

  In FIG. 3, the file control unit 210 of the present invention adds a partition file storage processing unit 211, a partition file restoration processing unit 212, a command detection unit 213, and a command determination unit 214 to the file control unit 410 shown in FIG. 7. It has a configuration.

  Further, the hard disk device (HD) 401 corresponds to the third auxiliary storage device 121 and has already been installed with software, and the hard disk device (HD) 402 corresponds to the fourth auxiliary storage device 122. And has a sufficient capacity for recording all the recorded contents of the hard disk device 401. On the other hand, the hard disk device (HD) 201 is the first auxiliary storage device 101 to be restored, has the same capacity as the hard disk device 401, and via the disk drive unit 202 in the same manner as the hard disk devices 401 and 402 described above. It is connected to the file control unit 210, and its recorded contents are initialized. Further, the CD-ROM 203 corresponds to the second auxiliary storage device 111, and the recorded contents are initialized in the initial state.

  In the file control unit 210 shown in FIG. 3, the command detection unit 213 receives an instruction input by the user via an input control unit (not shown), and when a predetermined copy command is detected, the corresponding copy is detected. The command is transmitted to the command determination unit 214. The command detection unit 213 is configured to send other input commands to the command processing unit 418 and to be used for normal file control command processing by the command processing unit 418.

  Further, the command determination unit 214 activates the partition file storage processing unit 211 or the partition file restoration processing unit 212 according to the type of the auxiliary storage device designated as the copy source by the copy command received from the command detection unit 213 described above. It is the composition to do.

  When the hard disk device 401 described above is designated as the copy source, the command determination unit 214 determines that the recording contents of the hard disk device have been instructed and starts the partition file storage processing unit 211, while When the ROM 203 is specified, it is determined that the restoration of the recorded contents of the hard disk device is instructed, and the partition file restoration processing unit 212 may be activated.

  As will be described later, the partition file storage processing unit 211 and the partition file restoration processing unit 212 control the respective units of the file control unit 410 described above to divide the recording contents of the hard disk device 401 into a plurality of partition files. Thus, a process of recording on the CD-ROM 203 and a process of reproducing the recorded contents of the hard disk device 401 from a plurality of partition files recorded on the CD-ROM 203 and restoring them to the hard disk device 201 are performed.

  FIG. 4 is a flowchart showing the operation of the file control unit 210 to which the present invention is applied. In step 301, when a file control command for the auxiliary storage device is input from the user or an application program, the command detection unit 213 first determines whether the input command is a predetermined copy command. (Step 302).

In the case of negative determination in step 302, the above-described input command is input to the command processing unit 418 via the command detection unit 213, and the command processing unit 418 responds to the input command with the file access processing unit 412 _1. , 412 ₂ , the file writing processing unit 414, the file reading processing unit 416 and the file transfer processing unit 417 are controlled to execute normal file control processing (step 303).

  On the other hand, in the case of the affirmative determination in step 302 described above, whether or not the command determination unit 214 has instructed to save the recorded content based on the type of the auxiliary storage device of the copy source designated by the input copy command. Is determined (step 304).

  If the hard disk device 401 is designated as the copy source auxiliary storage device, an affirmative determination is made in step 304 described above, and the partition file storage processing unit 211 starts operating in accordance with the determination result.

Partition file storage processing unit 211, first, via the file access processing unit 412 ₂ corresponding to the hard disk device 402 to open a file, for example, three blocks as block information file (step 305).

Next, the partition file storage processing unit 211 stores information recorded in an area including partition information (for example, an area from the first block to the third block) of the hard disk device 401 via the block transfer processing unit 419. It transferred to open Lot information file 402 (step 306), then, via the file access processing unit 412 _2, to close the block information file (step 307).

As described above, the partition file storage processing unit 211 controls the operations of the file access processing unit 4122 and the block transfer processing unit 419, thereby realizing the function of the partition information file creating unit 123 described in FIG. it can.

  At this time, the partition file storage processing unit 211 receives the partition information of the hard disk device 401 from the block transfer processing unit 419 and stores the partition information in the partition information holding unit 215 provided therein. Based on the information, the recorded contents of each partition of the hard disk device 401 are stored in the hard disk device 402 as one partition file.

  Here, the partition information described above includes information on the start position of each partition of the hard disk device 401 and the number of blocks included in the partition. Therefore, based on this partition information, the partition file storage processing unit 211 It is possible to know the size of a file necessary for storing the recorded contents of the section.

First, the partition file storage processing unit 211 obtains the start position P _i and the block number n _i of the i-th partition by referring to the partition information holding unit 215 (step 308), and the file access processing unit 412 _2. Then, a partition file having a capacity corresponding to the number of blocks n _i is opened in the hard disk device 402 (step 309).

Next, the partition file storage processing unit 211 notifies the block transfer processing unit 419 of the start position P _i of the i-th partition and the number of blocks n _i to instruct the transfer processing, thereby making this block transfer processing unit 419. Then, the recorded contents of all blocks included in the corresponding partition of the hard disk device 401 are sequentially transferred to the partition file of the hard disk device 402 opened in step 309 (step 310), and then the file access processing unit 412 _2. Then, the partition file is closed (step 311).

In this way, the partition file storage processing unit 211 controls the operations of the block access processing units 4111 and 4112 via the file access processing unit 4122 and the block transfer processing unit 419, so that the partition file described in FIG. The function of the creating unit 124 can be realized, and the recorded contents of all blocks included in the i-th partition of the hard disk device 401 can be copied to the corresponding partition file of the hard disk device 402.

At this time, the file access processing unit 412 _2, i-th partition file, the operating system currently running (e.g., MS-DOS), but is opened / closed as a file, information recorded in the partition file The block access processing units 411 ₁ and 411 ₂ provided by the BIOS or the device driver are used for transfer. Therefore, regardless of whether or not the i-th partition of the hard disk device 401 is a partition managed by the currently operating operating system, the recorded contents of this partition can be copied to the corresponding partition file. That is, if the above-described copy command is executed with MS-DOS running, the partition file corresponding to the partition composed of the OS2 file of the hard disk device 401 is also saved as the MS-DOS file.

  Thereafter, in step 312, it is determined whether or not a partition file corresponding to all the partitions from the first partition to the final m-th partition has been created, and in response to a negative determination, the process returns to step 308 to determine the next partition. If the above-described partition file creation process is repeated as a target, the recorded contents of all partitions of the hard disk device 401 can be stored in the corresponding partition file of the hard disk device 402.

The partition file storage processing unit 211 controls the operations of the hard disk devices 401 and 402 via the block transfer unit 418 and the block access processing unit 411 by performing the processing of step 305 to step 312 described above . The recorded contents of the hard disk device 401 can be completely copied to the hard disk device 402.

  In this way, when the creation of the partition file corresponding to all the partitions of the hard disk device 401 is completed, an affirmative determination is made in step 312, and the partition file storage processing unit 211 receives the hard disk via the file transfer processing unit 417. The partition information file of the apparatus 402 and all the partition files may be sequentially copied to the CD-ROM 203 (step 313), and the process may be terminated.

Here, each of the partition information file and the partition file created as described above can be managed using a file system provided by the currently operating operating system. That is, in response to an instruction from the partition file storage processing unit 211, the file transfer processing unit 417 performs the block access processing unit 411 ₂ and the disk drive unit 404 via the file access processing unit 412 ₂ according to a normal file transfer procedure. In addition to controlling the operation, the functions of the first file transfer unit 125 are realized by controlling the operations of the sector write processing unit 413 and the CD-ROM writer 405 via the file writing processing unit 414, and the hard disk device The partition information file and the partition file stored in 402 can be copied to the CD-ROM 203.

  On the other hand, if the CD-ROM 203 is designated as the copy source of the copy command input in step 301 described above, the determination in step 304 described above is negative, and in accordance with this, the partition file restoration processing unit 212 is determined. Starts operation.

  The partition file restoration processing unit 212 controls the operations of the sector read processing unit 415 and the CD-ROM reader 407 via the file read processing unit 416, and first reads the partition information file stored in the CD-ROM 203. (Step 314), the partition information holding unit 216 provided in itself holds the partition information of the hard disk device 401 included in the partition information file described above.

Next, the partition file restoration processing unit 212 directly sends the contents of the partition information file described above to the block access processing unit 411 ₃ corresponding to the hard disk device 201, and the disk drive unit via this block access processing unit 411 _3. By controlling the operation of 202, the contents of the partition information file described above are sequentially written from the first block to the third block of the recording medium of the hard disk device 201 (step 315).

As a result, the recorded contents of the first block to the third block of the hard disk device 201 and the first block to the third block of the hard disk device 401 can be reproduced. That is, the partition file restoration processing unit 212 executes the control processing of each unit described in step 314 and step 315 described above, thereby realizing the function of the partition information restoration unit 112 described in FIG.

  As described above, after reproducing the partition information of the hard disk device 201, the partition file restoration processing unit 212 sequentially performs the reproduction processing of each partition based on the partition information held in the partition information holding unit 216 described above. .

First, the partition file restoration processing unit 212 refers to the partition information holding unit 216 to obtain a block number P _i and a block number n _i indicating the start position of the i-th partition (step 316).

Next, read the partition file corresponding to the i-th compartment from CD-ROM 203 via the file read processing unit 416 (step 317), and sends the contents to the block access processing unit 411 _3, described above as the write start position by specifying the start position P _i, and writes the contents of the compartments file described above through the block access processing unit 411 ₃ to the hard disk drive 201 (step 318).

As a result, the recorded contents of the i-th section of the hard disk device 401 can be reproduced in a recording area composed of ni blocks starting from the Pi block of the hard disk device 201. That is, the partition file restoration processing unit 212 executes the control processing of each unit described in step 316 and step 318 described above, thereby realizing the function of the partition restoration unit 113 illustrated in FIG.

  Thereafter, in step 319, it is determined whether or not the sections corresponding to all the sections from the first section to the final m-th section have been restored, and in response to a negative determination, the process returns to step 316 to start from the next section file. By repeating the process of restoring the corresponding section, the recorded contents of all sections of the hard disk device 401 can be reproduced on the hard disk device 201.

  In this way, when the restoration processing corresponding to all the partition files stored in the CD-ROM 203 is completed, an affirmative determination is made in step 319, and the partition file restoration processing unit 212 determines all the partitions of the hard disk device 201. It may be determined that the restoration is finished and the process is finished.

Here, for example, the contents of the partition information file described above are the recorded contents of the first to third blocks of the hard disk device 401, and are complete copies including the data recording characteristics of the hard disk device 401. . Since this hard disk drive 401 and the hard disk device 201 is an auxiliary storage device of the same type that can be accessed according to the same standard, the contents of the partition information file described above is sent directly to block access processing unit 211 _3, directly hard disk drive 201 Can be written to the recording area.

That is, as described above, an auxiliary storage device of the same kind as the auxiliary storage device to be restored (i.e., hard disk drive) with the construction in which the mediating create a block information file and the zone file, partition information files and partitions Regardless of the type of recording medium in which the file is stored, the section information file and the contents of the section file can be handled as data suitable for the auxiliary storage device to be restored.

Therefore, in this case, existing software such as a file read processing unit 416 for reading a file stored in the CD-ROM 203 and a block access processing unit 411 ₃ for writing data to a designated block of the recording medium of the hard disk device 201. The functions of the partition information restoring unit 112 and the partition restoring unit 113 described above can be realized using the functions provided by the resources as they are.

Further , when a CD-ROM is used as a partition information file and a recording medium for the partition file, the CD-ROM is an irreversible recording medium, and is portable and can be copied in large quantities. Various advantages can be obtained.

  For example, using the personal computer system shown in FIG. 2, the partition information of the hard disk device in which the software is already installed, the partition information file corresponding to each partition, and the partition file are recorded on the CD-ROM 203. The CD-ROM 203 can be copied to a personal computer (hereinafter referred to as the CD-ROM 208) and sold.

  In this case, after the personal computer is sold, if the recorded contents of the hard disk device provided in the personal computer are accidentally erased, the user must install an operating system that can execute the predetermined copy command. It may be activated by some method and this copy command may be input using the above-mentioned CD-ROM 208 as a copy source.

  In response to this, the partition file restoration processing unit 212 operates and executes the restoration process described above, thereby shipping the recorded contents of the hard disk device based on the partition information file and the partition file recorded on the CD-ROM 208. It can be restored to the state of time.

  Here, since the CD-ROM is an irreversible recording medium, the information recorded on the CD-ROM 208 is not erased in a normal state, and is therefore suitable for storing such backup information. . Further, the storage capacity of the CD-ROM is several hundred megabytes, and has a sufficient capacity for storing the storage contents of a hard disk device provided in a normal personal computer.

  Therefore, according to the present invention, by attaching one CD-ROM 208 at the time of sale, the user can restore the hard disk device easily and reliably when necessary. Further, an application in which the CD-ROM 208 is delivered in response to a request from the user is also conceivable.

  In addition, if the partition information file and the partition file are respectively compressed and recorded on the CD-ROM 203 and decompressed during the restoration process, the auxiliary storage device having a capacity larger than the storage capacity of a normal CD-ROM can be restored. Can be applied.

  For example, as illustrated in FIG. 5, the partition information stored in the hard disk device 402 by the partition file storage processing unit 211 by adding a compression processing unit 221 and a file holding unit 222 to the file control unit 210 illustrated in FIG. 3. The file and the partition file may be transferred to the CD-ROM 203 via the compression processing unit 221 and the file holding unit 222.

In this case, the partition file storage processing unit 211, compression via the file access processing unit 412 _2, and sends to the compression processing unit 221 sequentially reads the block information file and the m partitions file, corresponding to each file Each time a result is obtained, the compression result is temporarily held in the file holding unit 222, and the contents of the file holding unit 222 may be written into the CD-ROM 203 using the function of the file transfer processing unit 417.

In this manner, the functions of the compression unit 141 and the second file transfer unit 142 described in FIG. 2 are realized, and the partition information file corresponding to the partition information of the hard disk device 401 and the recorded contents of the m partitions and m pieces of information files. Can be compressed and recorded on the CD-ROM 203.

  As a compression method used in the compression processing unit 221, a normal file compression method such as a run length method, an LZ (Ziv-Lempel) method, a Huffman method, or the like may be used.

  In FIG. 5, the partition file restoration processing unit 212 includes an expansion processing unit 223 that performs an expansion process that conforms to the compression process performed by the compression processing unit 221 described above.

In this case, the partition file restoration processing unit 212 first reads the compressed partition information file via the file read processing unit 416 and inputs the contents to the decompression processing unit 223 to reproduce the partition information. The obtained partition information is sent to the block access processing unit 411 ₃ , and the partition information is held in the partition information holding unit 216 for use in the restoration processing of the recorded contents of m partitions.

Next, the partition file restoration processing unit 212 sequentially reads out the m partition files compressed through the file read processing unit 416, inputs the contents thereof to the decompression processing unit 223, and plays back each of the reproduced partitions. The recorded content may be sent to the block access processing unit 411 ₃ .

The decompression processing by the decompression processing unit 223 described above is performed on the information of the partition information file and the m partition files compressed in this manner, whereby the first decompression unit 131 and the second decompression described in FIG. The function of the means 132 can be realized, and the original section information and the recorded contents of each of the m sections can be reproduced.

  As described above, when the partition information file and the partition file are compressed and recorded on the CD-ROM 203, even if the storage capacity of the hard disk device 401 exceeds the capacity of the CD-ROM 203, the single CD-ROM 203 is used. Information about the recorded contents can be saved and restored as necessary.

  As a result, the system of the present invention can also be applied as a backup system for a large-capacity auxiliary storage device having a capacity far exceeding that of a normal hard disk device.

A mini-disc is a recording medium having a smaller capacity than a CD-ROM. However, if the above-described compression process is performed, it is possible to compress the recording content of the hard disk device to a size about the capacity of the mini-disc. For this reason, it is possible to restore the recorded contents of the hard disk device by using the mini disk as a partition information file and a recording medium for storing the partition file . Of course, when the capacity of the hard disk device 401 is smaller than the recording capacity of the mini disk, the mini disk can be used as a recording medium for storing the partition information file and the partition file without performing compression processing .

  Here, when a mini-disc is used as a recording medium, it is necessary to provide a drive for the mini-disc in the personal computer, and the mini-disc is a reversible recording medium. The contents may be destroyed.

  However, when using a reversible recording medium such as a mini disk, the user can save the recorded contents of the hard disk device after purchasing a personal computer, and save a backup at an arbitrary point in time. be able to.

  While the base of personal computer users has expanded, accidents such as the hard disk device's recorded content being destroyed due to carelessness of the user have become more frequent, making it easier for users to deal with such accidents. It is extremely useful as a technique that makes it possible to cope with the above.
