Abstract
The invention discloses a USB virtual drive device capable of immediately switching virtual CD contents. The USB virtual drive device is characterized in that mapping files of a virtual CD are sorted in the file system of a conventional memory partition or a server of a flash memory in the form of common files, the CD mapping files in the formats of ISO, bin, ccd and the like in the common partition of equipment memory medium and selected catalogue contents in the file system of a common reading-writing memory partition are virtualized to the contents of the CD, and the files and the catalogues can be derived from multiple paths of the device. The device is independently implemented, can change the content of the virtual CD into a required CD according to specific requirement, thereby saving the time for changing the CD by formatting, and reducing the damage on the memory medium caused by repeated programming.
Description
Technical field
The present invention relates to a kind of computing machine USB peripheral hardware, relate in particular to a kind of USB virtual drive device of switching virtual CD content immediately.
Background technology
USB storage has not only replaced traditional floppy disk, CD to be used for file storage and exchange, but also can arrive USB storage to specific iso file programming by the format instrument, be modeled to the USB CD-ROM drive, realize that flash disk substitutes the CD-ROM drive install software, even carry out operating system installation, system maintenance etc.But the virtual drive of present USB storage format tool making can only be selected the content of virtual drive when format, in case just can not arbitrarily change the content of CD-ROM drive after programming is finished, that is: change the content of virtual drive and must carry out software formatization or programming with special-purpose instrument once more.This just makes and the content that a USB storage can only a virtual CD is for example become the mounting disc of Windows XP simplified form of Chinese Character by programming, in the time will WindowsServer 2008 being installed, and must reformatting.For the personnel that safeguard multiple systems, or prepare a plurality of USB storage at the different discs content, or need frequent format to come the content of switching virtual CD, consequently: it is time-consuming to require great effort, and makes mistakes easily, and efficient is low.
Summary of the invention
At above deficiency, technical matters to be solved by this invention provides a kind of hardware USB virtual drive device of switching virtual CD content immediately, virtual CD function independently realized by equipment, and can fast and convenient switching virtual Media Contents, to improve the service efficiency of virtual drive.
In order to solve the problems of the technologies described above, the invention provides a kind of hardware virtual drive USB device, comprising:
1, the image file that is used for virtual CD is present in the conventional partition holding of flash memory or the file system of server with the ordinary file form, can in the normal operations system, the file operation by routine come the additions and deletions image file, and can select/switch the CD content of current insertion virtual drive by configuration file on the common subregion and/or the hardware switch on the equipment.
2, the Disc image file of forms such as ISO, bin on the common subregion of device storage medium, ccd can be invented the content of CD subregion, promptly work as this flash disk insertion system and occur on computers as the USB CD-ROM drive, the content of CD is the Disc image file content in the CD-ROM drive.
3, the selected directory content on its common read-write partition holding file system can be invented the content of CD, promptly work as this flash disk insertion system and occur on computers as the USB CD-ROM drive, the content of CD is the file content of particular category in the CD-ROM drive.The file directory that is used for virtual CD can be selected/switch by configuration file on the common subregion and/or the hardware switch on the equipment.
4, be used for the Disc image file of the form such as ISO, bin, ccd of virtual CD, and be used for the catalogue of virtual CD content and the approach that file can come from this device, comprising:
Memory storages such as a, built-in flash memories, hard disk, CD;
Storage cards such as b, external portable hard drive, flash disk, SD card, CF card;
Remote server, main frame or the memory storage etc. of c, the wired or wireless connection by Ethernet, Wifi, bluetooth and other custom protocol.
In sum, the invention provides a kind of hardware virtual drive device, this content of installing virtual CD can be switched in use flexibly.Compared to present existent method and equipment, this device can become required CD to virtual CD content changing according to concrete needs, has saved the time that changes CD by format, has improved efficient, and has reduced programming repeatedly to the damage of storage medium.
Description of drawings
Fig. 1 is virtual CD data content of the present invention (sector) mapping and switching principle synoptic diagram.
Embodiment
Describe below in conjunction with the virtual optical disc apparatus principle of work of accompanying drawing the changeable content of the present invention.
Virtual CD data content of the present invention (sector) mapping and switching principle are as shown in Figure 1, at virtual CD and be used between the virtual ISO image file, there is a mapping table that switches by the configuration file control of hardware switch, logical circuit or ad-hoc location, this mapping table has determined to appear at the interior CD of virtual drive and the corresponding relation of common subregion ISO image file, and the content of the current image file of choosing promptly appears in the virtual drive.By changing this mapping relations, can realize " changing dish " operation fast.
Image file of the present invention need not special-purpose format/replication tool and writes, but exists with the form of ordinary file, can carry out the operation of ordinary file on computers, as: increase, deletion, move etc.; And device provided by the present invention can have a plurality of selective image files, changes the mapping relations of virtual CD and image file by software configuration file or hardware switch, fast the CD in the switching virtual CD-ROM drive.
Preferred embodiment of the present invention is: after USB virtual drive device is connected on the computing machine by USB interface, operating system identifies it with the form of USB mobile memory, this device provides a USB CD-ROM drive, also have one or more common read-write subregions simultaneously, be used for depositing the image file of virtual drive.
When the CD in this CD-ROM drive of host access, described USB device reads image files such as ISO, bin selected in the common read-write partitioned file system, ccd by hardware or embedded firmware, content with corresponding document returns to main frame with pursuing the sector, realizes the function of common CD-ROM drive.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
