Description

  The present invention relates to an information processing apparatus in which a virtual flexible disk device compatible with a flexible disk device is formed on a recording medium such as a hard disk, an information processing device management method, and an information processing device management program.

  A flexible disk (hereinafter abbreviated as FD medium) in which a magnetic disk on a flexible disk is housed in a protective case has been widely used as a data recording medium for computers. However, such an FD medium has been hardly used in recent years because of its small data recording capacity and low access speed. Along with this, many computers in recent years are not equipped with an FD device for recording / reproducing FD media. In addition, many companies that manufacture and sell external FD devices often stop manufacturing and selling external FD devices.

  However, there is a lot of data stored in the FD medium so far, and there is a demand for storing the data stored in the FD medium while maintaining the image file of the FD medium. If the data stored in the FD medium can be stored while maintaining the image file of the FD medium, the management of the FD medium becomes unnecessary, and the loss and misuse of the FD medium can be prevented, and the stored FD medium However, there is no risk of deterioration due to changes with time and unreadable due to seek error. In addition, when updating a BIOS (Basic Input Output System) or operating a different operating system, an FD device may be required to boot the system. Some programs operate by accessing the FD device. In order to operate such a program on a computer without an FD device, it is necessary to change the program.

  In view of this, for example, as shown in Patent Document 1, there has been proposed one having a virtual FD area that can be accessed interchangeably with an FD medium in a part of a storage area of a hard disk.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention forms a virtual FD device compatible with an actual FD device in a recording medium area such as a hard disk for a computer having no FD device, and can be used in the same manner as an actual FD device. It is what I did. In the following description, a virtual FD device on a recording medium is referred to as a virtual FD device, and an actual FD device is referred to as a real FD device.

  FIG. 1 explains the outline of the system of the virtual FD apparatus in the first embodiment of the present invention, and FIG. 1A shows the system configuration in the case of having the real FD apparatus 14. .

  As shown in FIG. 1A, an operating system 11 and a user program 12 are arranged in the logical memory space 10. SG (System Generation) information 13 is system design information. The actual FD device 14 is an actual FD device mounted on the system. Data 15 is data managed by a computer. The presence of the actual FD device 14 is recorded as SG information 13 at the time of system construction.

  As shown in FIG. 1A, when the real FD device 14 is attached, access to the FD medium is performed with respect to the real FD device 14. For example, when the user program 12 requests access to the FD medium, when access to the FD medium occurs, the user program 12 reads the SG information 13 and confirms that the actual FD device 14 is mounted. Then, the real FD device 14 is accessed.

  FIG. 1B shows a system configuration when the actual FD device 14 is not provided. As shown in FIG. 1B, an operating system 11 and a user program 12 are arranged in the logical memory space 10, and an FD management unit 21 is arranged. In addition, a virtual FD device 22 is generated in the hard disk device 20. The virtual FD device 22 has a data area compatible with the real FD device 14 formed on the storage area of the hard disk device 20. The FD management unit 21 manages the virtual FD device 22 and is loaded into the logical memory space 10 by the operating system 11.

  FIG. 2 shows an information table of virtual FD information included in the SG information 13. As shown in FIG. 2, the device name, the name of the FD medium, the comment, the creation date, the paid key, the HW identification number, the password, and the protection are recorded in the information table of the virtual FD information. The device name is the name of the device of the virtual FD device 22, and the name of the FD medium is the name of the FD medium virtually mounted on the virtual FD device 22. Information necessary for the FD medium is recorded in the comment. The creation date is the date when the data was updated or created. The paid key is information for installing paid software, and the HW identification number is an identification number unique to the device. The password is a password for protecting the information of the virtual FD device 22. Protect prevents data from being written or erased in the same way as a write protect notch of an actual FD medium.

  In FIG. 1B, for example, when the user program 12 requests access to the FD medium, the user program 12 reads the SG information 13 and determines that there is no real FD device 14, the FD management unit 21 Under the control, the virtual FD device 22 is accessed. At this time, the FD management unit 21 controls access to the virtual FD device 22 by using the virtual FD information included in the SG information 13. As shown in FIG. 2, the SG information 13 includes a device name, an FD medium name, a comment, a creation date, a paid key, a HW identification number, a password, and a protection as an information table of virtual FD information. . The FD management unit 21 controls access to the virtual FD device 22 using the key information included in the virtual FD information, so that the data of the virtual FD device 22 can be protected.

  FIG. 3 shows an example of processing for reading data of the virtual FD device 22 by restricting read access of the virtual FD device 22 using the password in the virtual FD information in the first embodiment of the present invention. It is a flowchart.

  In FIG. 3, when the user program 12 is activated and the user program 12 is a program for accessing the FD medium, the user program 12 reads the SG information 13 (step S101), and the real FD device 14 is connected. (Step S102). If the real FD device 14 is connected in step S102 (step S102 Yes), the user program 12 performs the reading process of the real FD device 14 (step S103).

  When it is determined in step S102 that the real FD device 14 is not connected (No in step S102), the user program 12 refers to the virtual FD information information table of the SG information 13 and the virtual FD device 22 imports the information. It is confirmed whether it has been performed (step S104). If the virtual FD device 22 has not been imported at step S104 (No at step S104), a device unconnected error occurs (step S105).

  As shown in FIG. 2, a password is recorded in the information table of the virtual FD information. If it is determined in step S104 that the virtual FD device 22 has been imported (Yes in step S104), the FD management unit 21 determines whether the password entered by the user matches the password in the virtual FD information information table. Is determined (step S106). When it is determined that the passwords do not match (No in step S106), the FD management unit 21 determines whether there is a password mismatch three times (step S107). If there is no password mismatch three times (No at step S107), the FD management unit 21 re-enters the password (step S108), returns to step S106, and determines again whether the passwords match. On the other hand, if the password mismatch is three times in step S107 (Yes in step S107), a password mismatch error occurs (step S109). When it is determined in step S106 that the passwords match (step S106 Yes), the user program 12 accesses the virtual FD device 22 (step S110).

  As described above, in the first embodiment of the present invention, by using the virtual FD device 22, the FD device 14 can be accessed without modifying the user program 12. A password is recorded in the information table of the virtual FD information of the SG information 13. By using this password, when the virtual FD device 22 is read, access to the virtual FD device 22 is restricted, and data of the virtual FD device 22 can be protected.

  Next, a writing process in the virtual FD device according to the first embodiment of the present invention will be described. In the first embodiment of the present invention, as shown in FIG. 2, on / off of protection is recorded in the information table of the virtual FD information in the SG information 13. When writing to the virtual FD medium, protection on / off is determined. When protection is on, writing to the virtual FD device 22 is prohibited. As a result, similarly to the write protect notch of the real FD medium, it is possible to perform the write prohibition process of the virtual FD medium, and it is possible to prevent data tampering and data loss during writing.

  FIG. 4 is a flowchart of an example of a writing process to the virtual FD device 22 in the first embodiment of the present invention.

  In FIG. 4, when writing to the virtual FD device 22, the FD management unit 21 refers to the virtual FD information information table of the SG information 13 shown in FIG. (Step S201). If protect-on is indicated (Yes in step S201), a protection error occurs (step S202), and the process ends without permitting writing. If protection is not ON in step S201 (No in step S106), the FD management unit 21 writes data to the virtual FD device 22.

  Next, paid software installation processing will be described. When the paid software is installed, the paid key and the HW identification number in the information table of the virtual FD information of the SG information 13 shown in FIG. 2 are used. Paid keys are used once installed, and are stored in a memory area that is not normally accessed. The HW identification number is information unique to each computer. When reinstalling the paid software, the identity of the device is confirmed by the HW identification information.

  FIG. 5 is a flowchart showing an example of processing when installing the FD medium of paid software in the first embodiment of the present invention.

  In FIG. 5, the installation program for installing the FD medium of paid software reads the SG information 13 (step S301), and determines whether or not the actual FD device 14 is connected (step S302). If it is determined in step S302 that the real FD device 14 is connected (Yes in step S302), a reading process to the real FD device 14 is performed (step S303).

  If it is determined in step S302 that the real FD device 14 is not connected (No in step S302), the installation program refers to the information table of the virtual FD information and confirms whether the virtual FD device 22 has been imported. (Step S304). In step S304, if the virtual FD device 22 has not been imported (No in step S304), a device non-connection error occurs (step S305).

  If it is determined in step S304 that the virtual FD device 22 has been imported (Yes in step S304), the FD management unit 21 determines whether or not the paid key has been used (step S306). If the paid key has not been used (No in step S306), it is determined whether the passwords match (step S307).

  If the paid key has been used in step S306 (Yes in step S306), it is determined whether the HW identification numbers match (step S308). If the HW identification numbers do not match (No in step S308), the medium An unauthorized use error occurs (step S309). If the HW identification numbers match at step S308 (No at step S308), the FD management unit 21 determines whether the passwords match at step S307.

  If it is determined in step S307 that the passwords do not match (No in step S307), the FD management unit 21 determines whether or not there is a password mismatch three times (step S310). Then, if there is no password mismatch three times (step S310 No), the FD management unit 21 re-enters the password (step S311), returns to step S307, and determines again whether the passwords match. . On the other hand, if the number of password mismatches is three in step S310 (step S310 Yes), a password mismatch error occurs (step S312). If it is determined in step S307 that the passwords match, the installation program accesses the virtual FD device 22 (step S313).

  As described above, in the first embodiment of the present invention, a paid FD medium can also be installed and used in an environment without the actual FD device 14 by importing it into the virtual device 22. In the first embodiment of the present invention, when a paid software FD medium is installed in the virtual FD device 22, a paid key is set in an area that is not normally accessed, and the paid software FD medium once installed is installed. The paid key is used and cannot be installed on other computers. In the first embodiment of the present invention, it is possible to reinstall paid software by determining whether or not the HW identification numbers match.

  As described above, in the first embodiment of the present invention, the virtual FD device 22 is formed on the hard disk device 20 so that even a user program that accesses the real FD device 14 does not modify the user program. By changing to the virtual FD device 22, it becomes accessible. Further, the data on the FD medium can be stored as the FD image, and it becomes easy to manage the data, and it is possible to prevent the data from becoming inaccessible due to a seek error or the like due to a change with time.
