Problems solved by technology

When the flash drive is picked up by others, because the flash drive does not contain any user identification information, it virtually increases the difficulty of returning
Furthermore, the increasing popularity of flash drives is also likely to cause most people to have the same style of flash drives, making it difficult to quickly identify the real owner of the flash drive
In such a case, the important data stored in the flash drive is also easy to be leaked because the flash drive is taken by others by mistake.

Abstract

The invention relates to a data processing method and system and a storage device controller. In the method, firstly, providing a storage device coupled to a host; issuing a write-in instruction including a logic access address and first data to the storage device by the host and judging whether the logic access address to be written in the host is one of logic access addresses of file system information; and writing second data into the storage device by the storage device in preset time when the logic access address to be written in the host is one of the logic access addresses of the file system information, wherein the second data is different from first data.

Description

technical field [0001] The invention relates to a data processing method, in particular to a data processing method, a system and a storage device controller for ensuring the specificity of a storage device. Background technique [0002] With the development of the Universal Serial Bus (Universal Series Bus, USB) specification and the rise of flash memory, portable flash drives have become one of the indispensable digital products for modern people. The advent of the flash drive also makes storage media such as 3.5-inch floppy disks (floppy disks) and optical discs dwindle due to shortcomings such as too small capacity and inconvenient data updates. [0003] As long as the computer system has a transmission interface compatible with the flash drive, it is very convenient to write data into the flash drive or to read the data in the flash drive, and thus the portability of data is greatly improved. Because of this, users are becoming more and more accustomed to using flash d...
