Description

technical field [0001] The present invention relates to the technical field of data security, in particular to a mobile storage device detection method, and a mobile storage device detection device. Background technique [0002] The development of the information age has prompted people to increase the demand for electronic information. In daily study, work and life, it is inevitable to involve the movement and carrying of electronic information, so the role of mobile storage devices has been appreciated. However, some unscrupulous manufacturers now use software as a mass production tool to change the main control information on the mobile storage device and mark the capacity of the mobile storage device as much larger than its actual capacity in order to make huge profits. When the actual capacity of the mobile storage device is less than Or when it is equal to 90% of its nominal value, it is considered to be a shrinking disk with quality problems. [0003] At present, one...
