Problems solved by technology
The above two multi-account hard disk data management systems have the following defects: the existing solutions are actually managed under the same address mapping table, so it is impossible to isolate the data of different accounts easily and effectively, and the operations of users are easy to affect each other. The management of different account data depends on the operating system, and the characteristics of the operating system itself have a great impact on account data management
[0003] In summary, the existing computer multi-user management system obviously has inconvenience and defects in actual use, so it is necessary to improve it.

Embodiment Construction
[0028] In order to make the object, 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 embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0029] see figure 1 , the present invention provides a multi-user hard disk system 100, the system 100 is preferably a solid-state hard disk system, which includes a classification module 10 and an identification setting module 20, and both the classification module 10 and the identification setting module 20 belong to the firmware of the hard disk, specifically:
[0030] After the hard disk is initialized, the classifying module 10 classifies the logical address-to-physical address mapping table stored in the hard disk. Generally speaking, the hard disk system 100 receives external commands to op...

The invention is suitable for the technical field of computers, and provides an implementation method of a multiuser hard disk system. The method comprises the steps: after hard disk initialization, hard disk firmware carries out sorting processing on mapping tables from logic address to physical address, which are stored in a hard disk; and different account identities are distributed to each type of mapping table, wherein each type of mapping table corresponds to one different system account. The invention further correspondingly provides a multiuser hard disk system for implementing the method. Therefore, different system accounts can be established independently of a specific operation system, and the data between different accounts are virtually independent, so that the data privacy of each account is ensured.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a multi-user hard disk system and its realization method. Background technique [0002] With the increase of computer penetration rate, information security has become very important. Existing computer systems can establish different accounts when multiple users use them. The specific implementation usually has the following two methods: 1) through the operating system, multiple users in the system are managed, and the management of different user data is generally realized by controlling file access rights; 2) according to the ATA protocol and file system rules, etc. The hard disk is partitioned, different systems are installed in different partitions, and the visible hard disk space of different operating systems is managed by using the startup boot program. The above two multi-account hard disk data management systems have the following defects: the existing solutions are ...
