Shrink disks are very common on the market. Most of these shrink disks display a large capacity. Sometimes we forget the actual storage space used by these pseudo-capacities and wake up when copying very large files, causing time errors. . So is there any way for us to display the true capacity of the shrink disk? Read below to learn how to shrink a USB flash drive and restore its true capacity.

How to restore actual capacity of a shrunk USB flash drive:

1. Check whether the U disk is a shrunk U disk:

1. Directly run the "360 Security Guard Download" program, find the "U Disk Identifier" tool in the "More Functions" list, and click the "Add" button.

2. After the "U Disk Identifier" is downloaded and installed, insert the U disk to be detected and click the "Start Detection" button to detect whether the current U disk is a "shrunk" U disk.

2. Restore the century capacity of shrunk USB flash drives - mass production:

1. You need to check the model of the shrunk USB flash drive. This can be done through tools such as "ChipEasy Chip Worry-Free Download".

2. Install and run the "ChipEasy chip worry-free" U disk parameter detection tool. From its main interface, you can get the "PID", "VID" and "main control chip model" of the shrunk U disk and other related parameters.

3. From the "Mass Production Tool" download interface that opens, find the "Mass Production Tool" that matches the "Master Control Chip Model" of the shrunken U disk and download it. After the download is completed, unzip and run the main program.
