Description of drawings
Fig. 1 is the structural representation that the utlity model has intelligent FAT table restore funcitons recording device.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
The recording device 100 with intelligent FAT table restore funcitons that the utility model provides as shown in Figure 1, comprises the storage unit 120 that is connected on the microcontroller 110, and described storage unit 120 is used to store the audio file of recording; Described storage unit 120 comprises the FAT table module 121 of include file folder title, file name and file name starting cluster corresponding relation.
Described storage unit 120 also comprises recovers module 123 and FAT table read module 124, described recovery module 123 can be under the control of described microcontroller 110, back up the content replication in the FAT table module 122 and cover described FAT table module 121 described, making the content modification in the described FAT table module 121 is that described backup FAT shows the content in the module.
Described recording device 100 also comprises the start button 130 that is connected on the described microcontroller 110, and after start button 130 was opened, the bootstrap module 111 in the described microcontroller 110 started.Described bootstrap module 111 is with the content in the described FAT table read module 124, and the 2nd FAT that the content that reads is write in the described microcontroller 110 shows read module 112.
FAT table in described FAT table module 121 and the backup FAT table module 122 damages and occurs in mostly under the situation of described recording device 100 power down.When recording device 100 power down, described FAT table module 121 is writing data, and the damage of described FAT table module 121 will take place; Described backup FAT table module 122 is writing data, and the damage of described backup FAT table module 122 will take place.Device 100 is provided with two FAT table modules in the recording of the present utility model, has guaranteed the normal of at least one FAT table, has increased the security of described recording device 100.
Described the 2nd FAT table read module 112 reads described FAT table module 121, judges whether described FAT table module 121 is normal.
If the result that described the 2nd FAT mark read module 112 is judged is that described FAT table module 121 is normal, described microcontroller 110 can continue to operate the utility model recording device 100 recording, duplicate, function such as deletion.Correct in described FAT table module 121, described backup FAT table module 122 is damaged, described microcontroller 110 can demonstrate information on the display unit of described recording device 110, the user need be connected recording device 100 with exterior PC, the described standby FAT table 122 of repaired by hand repeats no more here.
