Formatting (format) is executed to act and to be set as Hidden attribute hiding to realize.
Preferably, as shown in figure 5, the production method of above-mentioned mobile memory medium can also include:
Step S407: the main control chip parameter of above-mentioned movable storage medium is modified, wherein define above-mentioned second logical number
According to the address start-stop range in region, it is postposition loading method that above-mentioned second logical data area, which is arranged, reserves the friendship of key verification
Mutual interface.
Specific implementation is that modification movable storage medium (for example, USB flash disk) main control chip parameter is added with predefining this
Ciphertext data subregion has explicitly defined the address start-stop range of encryption data subregion, sets this encryption data subregion and is added using postposition
Load mode reserves the interactive interface of key verification.Wherein, for postposition loading method, when operating system is outside detecting
After setting USB flash disk connection system, it can be only done device initialization but this encryption data subregion cannot be loaded directly into, it is necessary to through user
It inputs password and can be loaded after being verified and allow user's normal definitions file system format and reading and writing data.
Preferably, as shown in figure 5, the production method of above-mentioned mobile memory medium can also include:
Step S409: the main control chip parameter of above-mentioned movable storage medium is modified, wherein define above-mentioned third logical number
According to the address start-stop range in region, Universal Disk Format (UDF) the file system that above-mentioned third logical data area is standard is set
System.
Specific implementation is modification USB flash disk main control chip parameter to predefine this simulation ISO driving subregion, is explicitly defined
The address start-stop range of good simulation ISO driving subregion sets the Universal Disk Format that this simulation ISO driving subregion uses standard
(UDF) file system.The boot partition for analog rom ISO is placed in simulation ISO driving subregion, which stores base
In the guidance data of ISO, system can be identified as CD-ROM form, using UDF file system, this subregion allow user at any time from
By replacing independent ISO data source therein, it can be the master ISO of guidable operating system, be also possible to the individual of user
Data class or the source operation and maintenance tools class ISO, and do not damage the data in other regions of USB flash disk in replacement accomplish lossless can freely continue
It updates.
Above-mentioned mobile memory medium (for example, USB flash disk) production program can be created that on a movable storage medium
Multiple functions of guiding install mediums just to have are needed in conversational traffic scene: what it is comprising windows, linux, MAC OS etc. is
System guidance and installation, system reparation when guidance is abnormal (including but not limited to: partition table creation, are sized and repair, disk
Reparation, data recovery, password cracking etc.), this production program makes O&M cost be effectively controlled, and O&M efficiency obtains pole
Big promotion, convenience be also it is self-evident, a USB port is also reduced to the occupancy of hardware resource, system break is worth
To being released effectively, the onboard voltage of hardware is released effectively and is utilized.
In conclusion by above embodiment provided by the invention, multi partition modular uses mobile memory medium
Memory space: conventional mobile memory medium (such as USB flash disk) using can only all be formatted as 1 memory space carry out using,
Space utilization rate is relatively low, and data storage is single, and function is also single, and uses this scheme can be with Multiple division memory space, number
It can classify according to storage, function is also no longer limited to single data storage, can integrate more other O&M functions.
The guidance of multihoming mode supports: conventional USB flash disk uses single guidance, and uses this scheme can be multiple
Guidance, the MBR guidance of covering Bios Legacy, the GPT guidance of EFI, the CD guidance of CD-ROM/DVD-ROM.
Support is installed in the guidance of multisystem: conventional USB flash disk is to be installed containing only single operating system, and use this side
Multiple operating systems can be written in case simultaneously, meet interior while each platform operating systems such as Windows, Linux, MAC OS
Embedding, for a disk in hand, installation is carefree, and upgrading embedded systems are mutually indepedent, do not destroy USB flash disk overall structure, accomplish lossless upgrade system
System source.
The support of encrypted data region: conventional USB flash disk can only carry out encryption after data by system-Level software, time-consuming to take
Force efficiency is low, and can mark off memory space in advance in the chip data piece of medium using this scheme, is defined previously as adding
Mi Qu, it is this encrypt in advance it is time saving and energy saving high-efficient, user password verification pass through after, use and be no different with conventional USB flash disk use,
It experiences fabulous.
Space independence is high: conventional USB flash disk is all being overall format before, once failure is encountered, no matter bottom is situated between
Quality and grade or file system level, the trial processing that all can only integrally erase restores, and uses this scheme, can be directed to particular problem
Region is individually handled, and the independence of each space utilization is very high, and overall data safety is also considerably improved.
Disclosed above is only several specific embodiments of the invention, and still, the present invention is not limited to this, any ability
What the technical staff in domain can think variation should all fall into protection scope of the present invention.
