Little TIPS About USB Flash Drives
Flash memory vendors are using decimal arithmetic data type: 1KByte=1000Byte, 1MB=1000KB, 1GB=1000MB; operating system mode is binary arithmetic : 1KByte=1024Byte, 1MB=1024KB, 1GB=1024MB; So there are some differences between nominal capacity and display capacity of flash memory products.
2GB is about 1.8-1.9GB
4GB is about 3.6-3.8GB
8GB is about 7.2-7.7GB
16GB is about 14.4-15GB
32GB is about 28.5-30GB
64GB is about 58.5-60GB

If you unplug a storage device or removable drive from your computer while it's transferring or saving information, you might risk losing some information.
Make sure that the computer has finished saving any information to the device before removing it.
If the device has a small light that shows when it's use, wait a few seconds after the light has finished flashing before unplugging it.
