Electronic flash memory external storage method and device

The invention provides a method for managing the data in the removable storage device. The method includes: applying or organizing or establishing or re-building the file managing system of the storage medium of said removable storage device according to the uses of said memory chips; and utilizing said file managing system to perform the corresponding processing in said memory chips according to the operation instructions of the host system, which is connected with said file managing system. By applying the method for managing the data in the removable storage device, which the invention provides, the capacity of the removable storage device can be extended, and the storage medium can be updated, thus the data security, the functions and the convenience of the system are increased.

Data managing method in a removable storage device

The present invention provides a method of data management for a flash memory medium, characterized in that the status flag of the memory block of said flash memory medium is set as an unfinished state during operating the memory block; after finishing the manipulation, the status flag is set from the unfinished to a finished state. This method ensures that the original data in the flash memory medium will not be lost even if the false power cut occurs when writing the data into the flash memory medium. The present invention also provides a method of writing and a method of recovering the data in the flash memory medium using the above-mentioned data management method.
