Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] figure 1It shows a flow chart of a method for realizing multiple partitions and multiple drive letters based on a single disk provided by an embodiment of the present invention, and the method includes the following steps:

[0044] S101. According to the number N of partitions required by the disk, assign N drive letters to the partitions, and set the starting addresses and capacities of the N partitions and drive letters on the disk, where N is a positive integer.

[0045] In this step, according to the number of partitions required by the disk, the disk refers to a single disk (including TF card, SD card, NandFlash, NorFlash or EEPROM, etc.), and the number of partitions on the disk is determined according to the actual needs of ...

Abstract

The invention relates to the technical field of computer information, and provides a method, system and device for achieving multiple partitions and multiple disk identifiers on the basis of a single disk. According to the method for achieving multiple partitions and multiple disk identifiers on the basis of the single disk, file management of a multi-user multi-attribute storage device is achieved, different levels of permissions are open to different levels of users, file management of multiple users and the openness of the system are improved, the experience degree of the users is greatly improved, and the technical problem of achieving multiple partitions, multiple disk identifiers and multiple attributes on the basis of the microprocessor single disk is solved. Meanwhile, compared with a technique of building a multi-partition interface in a Linux or wince system on the basis of a high-level ARM processor, single-disk multi-partition multi-disk identifier mapping can be achieved, the hardware cost of a product is greatly reduced, the product size space is decreased, and the competitive power of the product in the same trade is improved.

Description

technical field [0001] The present invention relates to the field of computer information technology, and in particular to a method, system and device for realizing multi-partition and multi-drive letters based on a single disk. Background technique [0002] Disk partition is essentially a format of the hard disk (for example: TF card), and then the hard disk can be used to save various information. When creating a partition, the physical parameters of the hard disk have already been set, and the storage location of the hard disk Master Boot Record (Master Boot Record, generally abbreviated as MBR) and boot record backup has been specified. Disk partitioning is to use the partition editor to divide several logical parts on the disk. Once the disk is divided into multiple partitions, different categories of directories and files can be stored in different partitions. The drive letter is the identifier of the DOS and WINDOWS system for the disk storage device. Once the disk w...
