Portable storage device dynamic management method

Abstract

The invention relates to a portable storage device dynamic management method. The portable storage device includes planning information and reservations areas of flash memory, retaining the plural to include access and replace the defective block activities blocks. The method including: providing a marker for configuration information to determine access to the state when the first marker is set to a state of open access to information for the district; and when the marker is set to section The state, district by restricting access to information. When the number of blocks than 0:00 activities will be marked set to open access to information for the 1st District state, when the activities of the number of blocks zero, it will be labeled as restricted data set access area was the second state, been in the area of information and access to the former interpretation of the mark, according to the state marker, decided to open up the area or restrict access to information and to access the information zone detection activities after block is the number zero, and if so, will be set to mark the second state to give portable storage devices more flexible access functions to attain dynamic management effectiveness.

Description

technical field [0001] The present invention relates to a portable storage device, in particular to a dynamic management of a portable storage device that can be automatically set or passively set by the user, and can flexibly change the access function and achieve dynamic management. method. Background technique [0002] In recent years, the concept of "carry data with you" has become more and more popular, making various portable storage devices, such as USB flash drives, MP3, CD or DVD discs, various memory cards and hard drives, etc. The most commonly purchased and used equipment. Among them, the USB flash drive is the most convenient and common. [0003] USB flash drives have bidirectional access functions that can be read and written. Compared with CD and DVD discs, USB flash drives have more writing advantages; USB flash drives can be plugged and played. Compared with various memory cards, USB flash drives It has the advantage of price and convenience of use; the v...

AI Technical Summary

Problems solved by technology

The reserved area mainly includes active blocks (Free Blocks), damaged blocks (Bad Blocks) and other blocks (Other Blocks). USB flash drives or MP3 need to use active blocks to achieve the purpose of data access, so the active area The number of blocks must be greater than 0, but the damaged block is relative to the active block, and one more damaged block needs to be replaced by an active block. Blocks increase gradually, so that the active blocks are relatively reduced. Once the number of active blocks is equal to 0, there will be no active blocks in the USB flash drive or MP3 to access (delete or write), and the life of the USB flash drive or MP3 will be short. ended and can no longer be used

[0008] This shows that the above-mentioned existing management method of portable storage device obviously still has inconvenience and defect in management method and use, and urgently needs to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general management method has no suitable method to solve the above-mentioned problems. This is obviously a Issues that relevant industry players are eager to solve
