Abstract
The present invention relates to a kind of implementation method of novel hard disk write once read many, this method is by being specific firmware code to hard disk upgrade, so that hard disk must can just be conducted interviews by supporting software client, and the specific locked hard disk of firmware code can not low lattice, computer can only recognize disk and can not but check amount of capacity, format and management etc..
Description
Technical field
Patent of the present invention is related to computer field of storage.
Background technology
Hard disk is one of the storage medium of computer mainly, is made up of the disk of one or more aluminum or glass system.
Disk is overcoating to be stamped ferrimagnet.
Dividing by type has solid state hard disc（SSD disks, modern hard disk）, mechanical hard disk（HDD conventional hards）, hybrid hard disk
（The new hard disk that mono- piece of HHD is born out based on traditional mechanical hard disk）.SSD is stored using flash memory particle, and HDD uses magnetic
Disk is stored, hybrid hard disk (HHD:Hybrid Hard Disk) it is one kind that magnetic hard-disk and flash memory are integrated together
Hard disk.Most hard disks are all Fixed disks, are fixed on by permanently sealing in hard disk drive.
There are 3.5 inches of desktop computer hard disks by size point, the positive strength of public attention is widely used in various desktop computers；2.5 inches of pens
Remember this hard disk, be widely used in notebook computer, all-in-one desktop machine, mobile hard disk and portable hard disk player；1.8 inches miniature
Hard disk, is widely used in Ultrathin notebook computer, mobile hard disk and apple player；1.3 inches of micro hard disks, product is single, and three
The exclusive technology of star, is only used for the mobile hard disk of Samsung；1.0 inches of micro hard disks, are developed, MicroDrive by IBM Corporation earliest
Micro harddisk（Abbreviation MD）, because meeting the standards of CF II, so being widely used in single anti-digital camera；0.85 inch of micro hard disk, product
It is single, the exclusive technology of Hitachi, it is known that for a hard disk mobile phone of Hitachi, a few money MP3 players of preceding Rio companies are also used
This hard disk.
When vital data are carelessly deleted, the when of being modified or written over, write once read many technology becomes one long
The ideal solution of the mass data information of safety storage long, and the magneto-optic of incorporated business's level is employed for write once read many technology more
In driver and tape-shaped medium, and hard disk is rare is related to, and this accounting for filing medium as backup to present hard disk is not directly proportional.
Patent of invention content
Patent of the present invention is related to a kind of implementation method of novel hard disk write once read many, and this method is by being specific to hard disk upgrade
Firmware code so that hard disk must can just be conducted interviews by supporting software client, and specific firmware code is locked
Hard disk can not low lattice, computer can only recognize disk can not but check amount of capacity, format and management etc..
This method can carry out head mark by software client to all data blocks of hard disk, that is, data block head
Portion has a marker bit, and marker bit represents when being " 1 " to represent that number can only be read with writing data blocks, marker bit when being " 0 "
According to block.All operations to be write, the advanced row data block header position enquiring of meeting, such as marker bit are " 0 ", write data to hard disk
Data block, and the marker bit write-in " 1 " of hard disc data block header position, such as marker bit are " 1 ", then returning " can not write existing
The error message of data block ".
Definition of this method to synchronous read-write, one is that all write operations are first head marker bits, then writing data blocks, such as
Have multiple threads while when writing identical block, be the first write-in ownership person with first writing head portion marker bit, behind thread not
Allow write-in；While uniformity and security in order to ensure data, when data block has in write-in, do not allow thread to have reading
Operation；Two be that read operation can simultaneously be carried out by multiple threads.
Brief description of the drawings
Fig. 1 is a kind of implementation method structural representation of novel hard disk write once read many of patent of the present invention.
Embodiment
In order that the object, technical solution and advantage of patent of the present invention are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, patent of the present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
Patent of the present invention, is not intended to limit the present invention patent.
Referring to Fig. 1, implementation method structural representations of the Fig. 1 for a kind of novel hard disk write once read many of patent of the present invention.
A kind of implementation method of novel hard disk write once read many, it is characterised in that 1, this method include hard disk firmware（10）, number
According to block marker bit（11）, data block（12）, hard disk（13）, software client（14）, computer（20）.
A kind of implementation method of novel hard disk write once read many, it is characterised in that the hard disk of this method（13）It is installed on calculating
Machine（20）, simultaneous computer（20）On software client is installed（14）, all computers（20）Reading and writing data access all need
To pass through software client（14）Management again to hard disk（13）Carry out.
A kind of implementation method of novel hard disk write once read many, it is characterised in that this method passes through software client（14）It is right
Hard disk（13）Progress is upgraded to specific hard disk firmware（10）, hard disk firmware（10）The functions such as low lattice, formatting by hard disk are locked
It is fixed so that miscellaneous equipment can only recognize hard disk（13）, it is impossible to recognize hard disk（13）Type and capacity and it can not manage hard
Disk（13）.
A kind of implementation method of novel hard disk write once read many, it is characterised in that the data of this method are by the data block read and write
（12）With data block marker bit（11）Composition, all data all pass through software client when carrying out write operation（14）Go inquiry
Corresponding data block marker bit（11）When value, such as data block marker bit are " 0 ", then data write respective data blocks；Such as data block
When marker bit is " 1 ", then " data with existing block can not be write " is returned to, read operation is not limited.
The preferred embodiment of patent of the present invention is the foregoing is only, patent is not intended to limit the invention, it is all at this
