1. What are the reasons why the capacity of U disk becomes smaller?

There are many reasons why the capacity of U disk becomes smaller. It is normal for the actual storage capacity of some U disks to be slightly different from the marked capacity, because computers use binary calculation methods, and U disk manufacturers generally use the conversion method of 1000M = 1GB, so the capacity of U disks is generally in the marked capacity. 93% are normal. However, if the capacity of the USB flash drive shrinks significantly, it may be due to the following reasons: 1. Memory damage: The memory of the USB flash drive may be damaged due to long-term use, frequent plugging and unplugging, or improper use, resulting in reduced capacity. 2. Computer virus infection: Some viruses may attack the USB flash drive, causing the memory to be damaged and the capacity to be reduced. 3. Partition error: Incorrect partition operation may cause the U disk capacity to be displayed incorrectly. This can be repaired by repartitioning or formatting. 4. After buying a shrunken USB flash drive from a counterfeit

, we need to be aware that this is a fraud. The so-called shrunk USB flash drive means that merchants use software to change the USB flash drive's master control information to increase the marked capacity of the USB flash drive, thereby deceiving consumers. Generally speaking, if the storage capacity of a USB flash drive is less than 90% of the marked capacity, it can be suspected that it is a shrunk USB flash drive. In order to detect the actual capacity of the USB flash drive, we can copy a file with a size similar to the marked capacity to the USB flash drive, and then check whether it can be opened normally. Shrunk USB drives often fail to be completely copied or the files are lost and cannot be opened after being copied. Therefore, we should remain vigilant and avoid purchasing such dishonest products to avoid financial losses.

The sudden reduction in the capacity of the U disk may be because the U disk has a damaged area. After formatting and repair, the damaged area will be hidden, resulting in a reduced capacity of the USB flash drive.

After the U disk is infected with a virus, hidden files may increase, resulting in a reduction in available capacity.
