Mobile storage medium management method, device and equipment and storage medium

Abstract

The invention discloses a mobile storage medium management method, device and equipment and a medium, and the method comprises the steps: writing an original file into a to-be-tested mobile storage medium, and determining the number of to-be-copied files according to the file size of the original file and the calibration capacity of the to-be-tested mobile storage medium; copying the original filein the to-be-tested mobile storage medium to obtain a copied file; comparing the original file with the copied file, and judging whether the original file is tampered or not; if yes, determining thatthe to-be-tested mobile storage medium is an expansion disk; and if not, returning to the step of copying the original files until the total quantity of the copied files reaches the quantity of the files to be copied. The method comprises the following steps: circularly copying an original file in a to-be-tested mobile storage medium to obtain a copied file; determining whether the file is tampered or not by comparing whether the original file and the copied file are consistent or not, so that a detection result whether the to-be-detected mobile storage medium is an abnormal capacity expansion disk or not is obtained, the problem of data loss is avoided, and rights and interests of users are effectively guaranteed.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a mobile storage medium management method, device and equipment, and a computer-readable storage medium. Background technique [0002] Expansion disk refers to U disk, hard disk, CD and other storage media by modifying the underlying parameters, so that the storage space presented is larger than its real storage space, which is essentially a shoddy product. When the size of the data stored by the user exceeds the real storage space of the expansion disk, the user's data may be overwritten, damaged or other irreversible data damage phenomena. [0003] In the traditional technical solution, after the user purchases the removable storage medium, it will be used directly. At present, the storage capacity of most mobile storage media is generally above 64G, but most users are likely to use only a small part of the storage space for a long period of time, which le...

AI Technical Summary

Problems solved by technology

At present, the storage capacity of most mobile storage media is generally above 64G, but most users are likely to use only a small part of the storage space for a long period of time, which leads to the fact that users may not know what they are using for a long time. Whether the storage capacity of the removable storage medium can reach the calibrated value

When the stored data exceeds the actual storage limit of the expansion disk, the user can find that the mobile storage medium he uses is an expansion disk. At this time, the user's data may have been damaged, which may cause data loss and seriously damage the user's data. Benefit
