Brief description of drawings
Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effects apparent by the specific embodiment of the present invention is described in detail.
In the accompanying drawing,
Fig. 1 is for realizing the theory diagram of hard disk data backup of the present invention and guard method;
Fig. 2 is the process flow diagram of hard disk data backup of the present invention and guard method.
Embodiment
Fig. 1 is for realizing the theory diagram of hard disk data backup of the present invention and guard method; Basic Input or Output System (BIOS) 40 (Basic Input Output System; BIOS) divide a zone as hard disk hidden partition 202 from hard disk 20; this hard disk hidden partition 202 is sightless 60 times at operating system of user; the user can be located at data backup software 601 on the operating system 60 by one and come backup information in the reading writing harddisk hidden partition 202, thereby makes backup information safety, hidden.
Fig. 2 is the process flow diagram of hard disk data backup of the present invention and guard method, may further comprise the steps:
Step 1: hard disk hidden partition 202 is set;
The hard disk hidden partition is set includes following steps:
Step 1.1: start BIOS40, read the size of hard disk 20, and be partitioned into certain zone as hidden partition 202 from hard disk 20;
BIOS40 reads hard disk 20 sizes in start-up course, and be partitioned into certain zone as hidden partition 202 (as the zone that begins to be partitioned into a certain size from hard disk 20 last sector as hard disk hidden partition 202) from hard disk 20, at this moment, the size in 60 times visible hard disk visible partition 201 of operating system equals the size that hard disk 20 total sizes deduct hard disk hidden partition 202.
Step 1.2: disk format hidden partition 202;
With system format chemical industry tool disk format hidden partition 202, make it have the file layout identical with operating system of user, also make it have storability simultaneously.
Step 1.3: the divisional type value that hard disk hidden partition 202 is set is and the different numerical value of current all divisional type values to make it have hidden attribute;
0 magnetic track, 0 cylinder, 1 sector position at hard disk is that (Main Boot Record, MBR), it comprises hard disk boot and partition table to Main Boot Record.The task that boot is finished is to check whether correct and definite which subregion can be operated system bootstrap to partition table.Partition table is positioned at the least significant end of this sector, at the deviation post 0x1BE of MBR, is opening flag with 80H or 00H, 0x40 byte altogether, and the information of every 0x10 byte records subregion can write down the information of four subregions altogether.The content of 2 follow-up bytes is 55AAH, and the data of expression MBR are legal available.What deserves to be mentioned is that MBR is produced by partition programs, it does not rely on any operating system, and the hard disk boot neither be unalterable, can be changed by the user, as long as it can finish aforesaid task.This also is the reason that can realize that multisystem starts why.Can write down 4 subregions in MBR at most, in order to break through this restriction, the notion of extended partition is introduced into.The user can create an extended partition (being called as main extended partition) in MBR, in this main extended partition, can create again extended partition and logical partition again, (their storage format subregion item in MBR is identical), and extended partition can continue to divide again.So just can construct partition table more than 4 subregions.Operating system is by the partition table access hard disk.By analyzing the partition table structure, can realize the operations such as establishment, deletion, modification, extraction, reduction of partition table.The type that a byte representation subregion is arranged in 0x10 byte in each of partition table is 0xb as the types value of FAT32, and the types value of NTFS is 0x7.
Numerical value different with current all divisional type values of definition is the types value of a subregion among the present invention, and therefore, operating system just can not be discerned this subregion, so just defines a special subregion, as a subregion that operating system is hidden.
Step 1.4: the initial physical address of hard disk hidden partition 202 is write a specific sector of hard disk.
Because the start address of hard disk hidden partition is not stored in the partition table, but is placed in the specific sector of hard disk (in last sector as hard disk), thus operating system of user identification less than, have hiding property.
Step 1.5:BIOS assigns guarded command, and hidden partition is protected.
By AT additional packet interface (AT Attachment Packet Interface; ATAPI) agreement is assigned guarded command to hard disk 20; hidden partition 202 is protected, because BIOS40 is to the rigid protection of hard disk, so even low lattice hard disk can not be corrupted to the data in the hidden partition yet.
Step 2: run user operating system 60;
Step 3: run book backup software 601 on operating system of user 60;
Step 4: data backup software 601 ejects the authentication window, imports username and password for the user,
If the username and password input is correct, execution in step 5;
If the username and password input error, execution in step 9
Step 5: start data backup software 601, load driver program on operating system of user 60;
Step 6: data backup software 601 reads hard disk hidden partition 202 physical addresss;
The initial physical address of hard disk hidden partition 202 is stored in last sector of hard disk in the present embodiment, and data backup software 601 reads the physical address of the hard disk hidden partition of last sector, searches out the position of hard disk hidden partition.
Step 7: carry out data backup by data backup software 601 access hard disk hidden partitions 202;
The user arrives hard disk hidden partition 202 by data backup software 601 Backup Datas and data, perhaps reads data to user's hard disk visible partition 201 from hard disk hidden partition 202.
Step 8: withdraw from data backup software 601, data backup software 601 unloads driver automatically simultaneously;
Step 9: return operating system of user 60.
Hard disk data backup of the present invention and guard method; data and the operating system of user of backup in the hard disk hidden partition isolated fully; can not lose because of system crash, partition table, virus infections and cause that data loses; even if user's hard disk suffers the havoc of low-level formatting and so on; the data that is kept in the hidden partition is still excellent; and the user is provided the one's own little world of a secret simultaneously, and store some secret significant datas, improve safety of data and confidentiality.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of accompanying Claim of the present invention.
