The above marks are reference values, and the actual data may have small gaps.

Q: I just received a USB flash drive. After accessing the computer, the display needs to be formatted and cannot be formatted or displayed with a capacity of 0 bytes.

A: This situation mainly occurs in 64G or more (including 64G) large capacity U disk. On XP computer systems, XP systems cannot support large-capacity USB flash drives in EXFAL format. It is recommended to download XP system or support large capacity U disk. The patch is downloaded and installed on the XP system computer, rebooted, and the USB flash drive can be used normally. Or connect the USB flash drive to a W7 or higher computer and right click on the removable disk – format – file system select FAT32 – boot – format to re-access the XP system to be used.

Q Why is there a difference between reading speed and promotion?

A: Reading speed will vary depending on your computer configuration. In addition, the instantaneous read/write speed fluctuates due to the difference in CPU usage and copy file path depth. If you want to test speed, it is recommended to use professional test software to test the speed. In addition, the USB3.0 interface USB flash drive requires USB3.0 speed and needs to be used on a USB3.0 interface computer.

Q: Why can’t my USB flash drive be recognized on TV and onboard?

A: Connect a USB flash drive to your computer to view the following format. For example, if the USB flash drive is not in FAT32 format, you will need to format the USB flash drive to FAT32 format on your computer. If you are sure that the USB flash drive is in FAT32 format, the compatibility of the FAT32 format is very broad. There are still many devices.

Q: Why can’t my U disk copy a single file larger than 4G?

A: Since the USB flash drive is formatted in FAT32 format at the factory, this format cannot store a single file larger than 4G. You need to format the USB drive to EXFAL format and store it. (Note: Cannot be formatted as NTFS format, although NTFS format pages can support a single file on 4G, but NTFS format is not recognized on Apple phone tablets)

Q: Why is the actual capacity displayed less and normal?

A: Regarding the difference in actual capacity, there is a computational difference between the chip calculation method and the factory operating system (chip 1G = 1000M, operating system 1G-1024M). The format of the product itself also takes up a small amount of space, so the difference between the actual capacity of the operating system and the capacity shown by the actual capacity is normal, such as 16 GB, the computer recognition is about 14.4 G, and the 32 GB computer recognition is about 29 G. .

Q: Why is the USB port of my USB flash drive slightly loose or tight?

A: It is normal for the USB interface to be slightly loose or too tight. Due to the poor quality of the USB interface of different hosts and laptops, the use of environmental materials, thermal expansion and shrinkage and other factors.

Q: If my USB flash drive fails, can the data be recovered?

A: It is recommended to perform important data backups. Official after-sales service does not include data recovery services.
