Memory device with multiple management identity and management method thereof

Abstract

The invention relates to a storing apparatus with multiple management identities and managing method thereof, the storing apparatus comprises a first storage space and a second storage space, the first storage space is corresponding to a first management identity, the second storage space is corresponding to a second management identity, the storing apparatus is coupled with the storage space and the second storage space by a control unit, the control unit can select the first storage space or the second storage space according to a selection signal corresponding to the first management identity or the second management identity in order to use the first storage space or the second storage space for the computer system, thereby increasing the usability of the storing apparatus.

Description

Technical field [0001] The present invention relates to a storage device, and particularly refers to a storage device with multiple management identities and a management method thereof. Background technique [0002] According to, the current ways of storage devices to access information can be roughly divided into fixed and portable. Fixed storage devices usually have a larger storage space, which can be used to store a large amount of data and programs on storage devices, such as hard disks ( Hard Disk), but the disadvantage of fixed storage devices is that they are inconvenient for users to carry when they must be used at any time. Therefore, portable storage devices are favored by users because of their portability. For the above-mentioned requirements, conventionally known technologies have developed Micro Drivers, Memory Sticks (Memory Stick, MS) or Compact Flash Cards (Compact Flash Card, CF Card), etc. The function of storing data is achieved. However, although the above-...

[0002] By the way, today's storage devices access information can be roughly divided into fixed and portable. Fixed storage devices usually have a larger storage space, which can store a large amount of data and programs for the storage device, such as hard disk ( Hard Disk) etc., but its disadvantage of the fixed storage device is that it is inconvenient for the user to carry when it must be used at any time, so the portable storage device is favored by the user because of its portability. The above-mentioned requirements have been developed into micro-hard drives (Micro Driver), flash memory cards (Memory Stick, MS) or compressed flash memory cards (Compact Flash Card, CF Card) etc. The function of storing data is achieved, but although the above-mentioned data storage device can achieve the function of storing data, it cannot further achieve the functions of data management and space management

[0003] Continuing from the above, whether it is an enterprise or a personal storage device, it will face the problem that multiple people use the same data storage device, that is, a data storage device must be used by different people at different times, because each person The work attributes and user needs are different, so everyone has their own confidential data, but the conventional fixed storage device cannot completely divide and protect the function. In terms of hard disk, although it can be divided There are several areas, but there is no mechanism for separately encrypting the space of each area, which will result in a lack of data confidentiality, and in terms of currently widely used operating systems, it can only encrypt specific files or folders , if you want to encrypt the files and folders in the entire area space one by one, it will bring a lot of trouble to the user
