FIG.

1, a first sector 100 corresponding to the first sector and partition information of the entire sector 10 are recorded and a predetermined portion of the first sector 100 is recorded in the first sector 100, A storage 300 that can be divided into a plurality of partitions by a user and an empty space 400 that is not used by the user because it is not included in the storage 300, And a last sector 500 at the end of the entire sector 10.

The entire sector 10 refers to all sectors configured in the mobile storage device, and is equal to the total storage space, and is usually calculated as 512 bytes per sector.

The first sector 100 corresponds to a sector 0 of the entire sector 10 and is mainly included in the header 200 to participate in a part of recording the partition information.

A header 200 is formed from the first sector 100 to a certain sector of the entire sector 10 and describes the partition information of the entire sector 10.

Here, the operating system is an execution manager that manages all hardware and all software, and there are various operating systems such as Windows, MAC, Linux, and Unix.

In addition, the header 200 reads the operating system and partition information installed through the header 200 when the computer is booted, so that the files stored in the corresponding operating system and partition are retrieved, and the user can use the storage device.

In addition, the header 200 can be divided into a plurality of partitions by changing the record of partitions and operating systems, and the partitioned partitions can be formatted and used by the user as an operating system and file storage.

The header 200 may be composed of an MBR 210, a GPT 230, and a hybrid MBR 250 according to a partitioning method. In the present invention, one of three types of the header 200 is configured.

Since the MBR 210 is an abbreviation of Master Boot Record, the basic partition information and the operating system information of the entire sector 10 are described and can be divided into a maximum of 4 partitions, a single partition uses up to 2TB, You can boot the Microsoft operating system.

The MBR 210 is divided into a boot code 211, a partition table 213, and a signature 215.

The boot code 211 is composed of 446 bytes in the first sector 100 of the MBR 210 and performs a function of finding the first sector of the activated partition table 213 by scanning the activated partition.

The partition table 213 is configured after the boot code 211, and is composed of 64 bytes in total, and records the active state, the start CHS, the type of partition, the last CHS, the LBA of the first sector, and the number of sectors.

Here, the starting CHS (Cylinder-Head-Sector) is the address of the first sector of the partition, the last CHS is the address of the last sector, and the LBA (Logical Block Address) is the sector number.

A signature 215 is configured after the partition table 213 and is composed of 2 bytes and is denoted AA55 or 55AA depending on the manufacturer.

The GPT 230 is an abbreviation of the GUID partition table. The GPT 230 describes basic partition information and operating system information of the entire sector 10, and can be divided into 128 partitions. However, the Windows operating system can not be booted.

The hybrid MBR 250 refers to a method in which basic partition information and operating system information are described by the MBR 210 in the information partitioned by the GPT 230. In the portable storage device supporting the GPT 230, It is possible to boot a part of Windows operating system.

A storage 300 having a predetermined space for storing an operating system and files is divided into a plurality of partitions using a partition program so that a user can partially use an operating system and files.

At this time, when the header 200 is divided into the partitions, if the MBR 210 is the MBR 210, the first partition 310, the second partition 330, the third partition 350, the fourth partition 370, And if the header 200 is a GPT 230, a maximum of 128 partitions can be divided.

The first partition 310 includes a first VBR 311, a first data 313 and a first empty sector 315. The second partition 330 also includes a second VBR 313, Data 333, and a second empty sector 335.

The VBR 311, 331 is an abbreviation of Volume Boot Record. The VBR 311, 331 is formed at the front of partitioned and divided partitions, and includes information such as the file system in which the partition is formatted and the physical storage location of the data.

The data 313 and 333 are spaces for storing an operating system or a file in each partition.

Empty sectors 315 and 335 refer to the remaining space using VBRs 311 and 331 and data 313 and 333 in the respective partitions.

3, when the operating system is installed in the second data 333, the second empty sector 335, which is installed and remained, is merged into the first partition 310, 2 empty sectors 335 are also configured for use by the user.

For example, the size of the second empty sector 335 is 8 GB, and the size of the second empty sector 335 is 20 GB, and the size of the operating system installed in the second partition 330 is 12 GB. Is manually or automatically merged into the first partition 310 so that the user merges 8 GB of the second empty sector 335 with the first partition 310 so that the user can utilize a wider space do.

In addition, the window and MAC of the operating system recognize the removable storage device as a single partition, and recognize only the corresponding partition number, so that the partition is divided into the partitions, so that all the partitions other than the second partition 330 are not recognized It is structured so as to preserve the security of important confidential data, source code, design drawings saved by the user.

In addition, when the second empty sector 335 merges into the first partition 310, a manual mode in which a user directly performs a partition merge using a separate partition program and a second partition 333 in which a separate partition It can be configured in automatic mode to automatically merge the partitions by installing the program, which is configured according to the type of operating system and removable storage device.

Specifically, the manual mode is set by changing a part of the information of the header 200 into a separate partition program to merge the space of the second empty sector 335 of the second partition 330 into the first partition 310 , And the automatic mode is configured such that a separate partition program is installed in the second data 333 installed in the operating system so that the partition program is automatically set at the time when the computer is booted.

Meanwhile, the entire sector 10 is structured so that the user can use all the files stored in the portable storage device in the PC by fileing or imaging the partitioning information, the operating system mounted on each partition, and various files.

In the conventional method, as shown in FIG. 4, low-level copying is performed to all empty sectors 315 and 335 and empty space 400 in addition to the data to be filed.

However, since this method takes a long time and it is troublesome to copy unnecessary parts, according to the present invention, as shown in FIG. 5, the second empty sector 335 and the remaining part excluding the empty space 400 In other words, low-level copying of the header 200, the first partition 310, the second VBR 331, and the second data 333 can save a lot of time.

In this case, there are a high-level copy and a low-level copy, and a high-level copy can copy only a visible file as a file is copied by drag & drop or copy & paste method. (200), VBR (311, 331), empty space (400), etc. are not copyable, but are convenient for the user to use.

In other words, High-Level copy refers to a commonly used copy method.

The low-level copy is a method of copying a storage medium or a file in byte units. The low-level copy is a method of copying from the first sector 100 to a sector designated by the user, (311, 331), empty space (400), and the like.

That is, since the low-level copy can copy information that can be executed by the operating system such as the header 200 and the VBRs 311 and 331, the low-level copy copies the operating system into a low-level copy and converts it into an image file.

For example, by designating the second partition 330 in which the operating system is installed from the first sector 100 to the last sector of the second data 333 of the second partition 330 and performing Low Level copy, 311,331) into an image file such as * .img or * .iso.

In another mobile disk, the addresses from the existing first sector 100 to the sectors of the second data 333 are converted into image files in the same manner, and then the image files including the operating system are overwritten, .

The reason for installing the operating system by converting to the image file is that the developer can mass-produce the image by overwriting the other removable disk with the low-level copy method, and the manufacturing process is simple and time can be saved.

The reason why the image file is converted and used is that it is distributed online and installed in a removable memory in which the user has stored the image file, and whether the operating system loaded with the unique number is an operating system provided by the supplier or an unauthorized copy If the operating system provided by the operator is used, the update is provided free of charge. In the case of using the operating system without permission, the trial version or the update can be set not to be provided.

The free space 400 is an unallocated partition and refers to a sector that is not usable by a user who has not partitioned in the storage 300. To use the free space 400, .

The last sector 500 corresponds to the last sector of the entire sector 10.

Although the present invention has been described in connection with the preferred embodiments thereof with reference to the accompanying drawings, it is to be understood that the present invention is not limited thereto, It is to be understood that various modifications and changes may be made without departing from the scope of the appended claims.
