Data judge that the video data answering region to be recorded in SD card accordingly is that abnormal data (i.e. may produce the storage of corrupted data
The data of storage in card region).
(2) after there is above-mentioned exception, it is judged that whether the video data being defined as abnormal data in SD card can recover, root
It is judged that result is handled as follows:
(21) judge the video data being defined as abnormal data as recovering, then by the abnormal signal in FLASH memory
Data deletion, and the video data of respective stored card region storage in SD card is carried out repair process, the video that will store
Data add data end to end, form the video file that one section of system is readable；
(22) judge that the exception in FLASH memory as irrecoverable, is then believed by the video data being defined as abnormal data
Number is deleted；Further, in this process, it is also possible to the while of the expendable video data that will preserve in SD card
Delete, to obtain more SD card memory space.

Judge that video file is whether as continuously etc..Such as, when drive recorder carries out videograph, it is to carry out according to preset capacity
Storage, it is assumed that preset capacity is 200M (million) video data, the most often records the data of 200M (million), just generates
One video file, if it is decided that the video file of record has reached above-mentioned standard, then determine that it is complete video
File；Or, as described in Figure 3, if according to above-mentioned index information (the i.e. storage in SD card that recorded in FLASH
The numbering in card region) video data that finds is continuous print video data, is i.e. stored in the video counts of zones of different in SD card
According to corresponding can connect composition continuous print video file end to end, then determine that it is continuous print video data, it may be assumed that according to
Index information in FLASH memory finds the memory area in SD card, contains next memory area in this region
Index information, can find next memory area according to this index information, if judging, occurring the data of abnormal area to be belongs to
This kind of continuous print data these memory areas reach predetermined number, then can determine that as recoverable continuous print video data.
