Problems solved by technology

[0006] Universal Serial Bus flash memory devices are widely popular for storing data. Although traditional USB flash memory devices can only store data, they are popular because they are portable, easy to delete, and easy to format. The traditional USB flash memory device has a potential problem. Because it is easy to delete and format, data may be deleted or formatted accidentally. Therefore, the USB flash memory device is generally used for transfer Data rather than for permanent storage, data stored in a USB flash memory device is typically backed up elsewhere, such as a hard drive

[0095] Figure 5 It is an example of a conversion table 500 with four partitions, which can be used to implement in the present invention image 3 The index 220 of Figure 4 or the address conversion table 420 of Figure 4, the conversion table contains logical unit numbers 500, 502, 504 and 506, and the logical unit numbers 500, 502, 504 and 506 are also referred to as logical unit number 0, logical unit number 1. Logical unit number 2. Logical unit number 3. In a particular embodiment, the CD ROM partition is assigned to LUN 0500, Windows will give LUN 0500 the highest priority and display lower disk labels, LUNs 502 to 506 are each assigned For different partitions, the partition related to the logical unit number 502 is password-protected, while the partitions related to the logical unit numbers 504 and 506 are public partitions, that is, general access is possible. In this example, two public partitions are useful for data wrangling.

Abstract

The present invention provides an electronic data flash using various flash memory cells to build USB sata flash cards with multiple partitions and autotun function. The electronic data flash card includes a processor and at least one flash memory device. The flash memory is partitioned such that it includes a first partition that is formatted using a file system that supports an Autorun function (e.g., CD-ROM file system (CDFS) format, fixed-disk format or Universal Disk Format (UDF)), and a disk partition that is formatted using a typical controller-based flash device file system (e.g., 16-bit File Allocation Table (FAT16) file system, 32-bit FAT (FAT32) file system, or New Technology File System (NTFS)). The electronic data flash card is produced such that Autorun-enabled application automatically executes a predetermined application or action when the electronic data flash card is installed in a host system. In one embodiment, the Autorun application includes an advertisement displayed on the host system prior to allowing access to data stored in the disk partition.

Description
