Embodiment Construction

[0027] The universal serial bus interface mobile data storage method that the present invention proposes, its flow process is as shown in Figure 1, at first the data storage area is divided into three areas as shown in Figure 2: read-only self-starting area, user visible area and user invisible area The visible area, the read-only self-boot area is used to store management data, the user-visible area is used to store user usage data, and the user-invisible area is used to back up user usage data.

[0028] The management data received from the main controller is stored in the read-only self-starting area in the above-mentioned data storage area, and the exclusive authorization instruction received by the main controller from the personal computer sets the management data to be non-modifiable.

[0029] According to the above-mentioned management data in the read-only self-starting area and the instructions of the remote server, a user-used data start-up list, a data update list, ...
