Fig. 1 is the flow chart of the method that the embodiment of the present invention provides;
Fig. 2 is the schematic diagram of the device that the embodiment of the present invention provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on Embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained, broadly fall into present invention protection Scope.
Seeing Fig. 1, the Ile repair method that the embodiment of the present invention provides comprises the following steps:
S101: after detecting that movable storage device inserts, monitoring is stored in the operation of file to described movable storage device;
Firstly the need of explanation, during owing to writing a file in movable storage device, it is not to be saved in shifting at once In dynamic storage device, but first it is stored in relief area, waits accumulation to be saved in the most together in movable storage device.As Fruit the most successfully unloads and the most illegally extracts movable storage device, and system is ignorant, and the function such as fopen, fwrite is the most still Return correct, the when of until operating system to be deposited into the data in relief area in movable storage device, just can point out I/O Mistake, therefore, a lot of data all can be lost because of this error reporting not in time.
From the above, in actual applications, if performing the operation being stored in file in movable storage device, The most once movable storage device is illegally extracted, and will there is the risk that file has damaged, and the file damaged is exactly this The file being stored into, and other the original files in movable storage device, the most typically will not damage.Therefore, real in the present invention Execute in example, can only operation to being stored in file in movable storage device be monitored.
Wherein, owing to being inserted by USB interface at movable storage device, or when USB port is extracted, USB device driver Will modify CONFIG.SYS, such as USB device driver can be when inserting or pull out toward "/proc/scsi/usb- Storage-0/0 " the inside note upper " Attached: Yes or No ", therefore, by checking that this file just can detect shifting Whether dynamic storage device inserts or pull out.
S102: when being stored in file in described movable storage device, the source path of record this document and described movement The identification information of storage device;
Wherein, when being stored in file in movable storage device, it is common that after certain local for computer file is replicated, viscous It is attached in movable storage device, or certain file that computer is local " is sent to " in movable storage device, etc..Therefore, " source path of file " described in the embodiment of the present invention refers to, and is stored in the file of movable storage device in computer this locality Path.Such as, certain file path in computer this locality is " F: work relevant XX.txt ", then be deposited into by this document Time in movable storage device, the source path of this document is exactly " F: work relevant XX.txt ".
The identification information of movable storage device refers to uniquely to identify the information of a movable storage device, a movement Storage device is in the Shi Douhui mark with uniqueness, such as, serial number of USB flash disk etc. of dispatching from the factory.Therefore, when implementing, just The identification information of movable storage device can be obtained by obtaining the serial number of movable storage device, such as, pass through This function of DriveGetSerial, can get the serial number of movable storage device, then record.
Certainly, after being inserted on computer by a movable storage device, multiple file may be stored in wherein, this Time, the source path of each file can be recorded in the way of form, the corresponding same movement of the source path of these files Storage device identification.
S103: if be detected that illegally extract the message of described movable storage device, then described record is preserved;
When movable storage device is wiped from USB port, if using normal Uninstaller successfully to unload, then system One can be produced and represent the message normally extracted, such as " IRP_MN_REMOVE_DEVICE ";And if illegally extracting a shifting Dynamic storage device, then, after system discovery, can produce one and represent the message illegally extracted, such as " IRP_MN_SURPRISE_ REMOVAL”.Therefore, by obtaining the message that system produces, can judge that movable storage device is normally to extract, or quilt Illegally extract.If illegally extracted, then the information recorded before can be preserved, for follow-up use.Certainly, if It is normally to extract, does not the most generally have the phenomenon that file has damaged, therefore, in order to avoid memory space is caused wave Take, the record obtained before can be destroyed.

S105: if it is, utilize the document source path in the record of described preservation that the described file damaged is entered Row is repaired.
When movable storage device is re-inserted into, if it find that this movable storage device is when inserting last time, by illegally Extract, and file therein damages, it is possible to the source path about file preserved before utilization, to the literary composition damaged Part is repaired.
Specifically when the file damaged is repaired by the source path utilizing file, can take automatically to replace or The multiple implementation such as semi-automatic replacement.Wherein, so-called automatically replacement refers to, directly the document source path from record obtains Damage the source file of file, the most directly replace the file damaged with this source file.So-called semi-automatic replacement refers to, First the document source path of record can be supplied to user, then manually be reacquired literary composition according to this source path by user Part, and replace the file damaged, etc..Certainly can also there is other implementation, will not enumerate here.
In a word, in embodiments of the present invention, owing to recognizing the file being deposited in movable storage device, it is common that from meter In calculation machine, in the copy past, therefore, the most generally remain with source file, so, when the file in movable storage device When damaging, it is possible to utilize the source file retained in computer, it is repaired.
Certainly, in actual applications, it is also possible to situations below occurs: when movable storage device is re-inserted into computer Time upper, computer may be deleted about certain source file having damaged file or move under other path, this Time, just according to the source path of file, the file damaged cannot be repaired.In order to tackle the generation of this situation, In the embodiment of the present invention, it is also possible to when the message illegally extracting movable storage device being detected, set being deposited into mobile storage Standby file backs up, and so, can not repair, if, with the document source path in record, the file damaged Merit, then can utilize the file of backup to repair the file damaged.It is of course also possible to be not to find that mobile storage sets Just source file is backed up for when illegally extracting, for example, it is also possible to source file is tracked, finding that source file is deleted When removing or moved, then source file is backed up.Or, when finding that source file is moved, it is also possible to will preserve before The source path about this document be revised as mobile after path, so, equally realize repairing the file damaged Multiple.
