2. If there is data exchange, the storage structure of the U disk may be damaged, the files may be destroyed, and sometimes the U disk may be burned. Damage to the motherboard may also occur.
Directly pulling out will damage the performance of the U disk to a certain extent
If the U disk is still caching data and has not been completely written, if you directly Unplugging the USB flash drive will result in data loss, failure to recognize the device, need to format, need to repair sectors, etc.
Direct unplugging may cause the computer system to slow down and the resource manager to crash (or even restart)
The data suddenly loses its target in the cache, which may lead to the above There are some problems, so in order to avoid this situation, Windows has added a "safe ejection" function. This function is to check whether the data in the external storage has been read or written. If it is not read or written, the power can be cut off.

Precautions when using U disk:
1. U disks generally have a write-protect switch, but it should be switched before the U disk is inserted into the computer interface. Do not switch it while the U disk is working.
2. The U disk has a working status indicator light. If it is an indicator light, when it is inserted into the host interface, the light will turn on to indicate that the power is on. When the light flashes, it means that data is being read and written. If there are two indicator lights, usually two colors, one lights up when the power is turned on, and the other lights up when the USB flash drive is reading and writing data.
3. Some U disks are still working after the system copy progress bar disappears. It is strictly forbidden to unplug the U disk when the read and write status light is on. Be sure to wait until the read/write status indicator light stops flashing or goes out before unplugging the USB flash drive.
4. Some brands and models of U disks reserve less space for the file allocation table, and are prone to error messages when copying a large number of single small files. At this time, you can stop copying and compress multiple small files into A large file solution.
5. Do not insert the U disk into the computer before the computer starts up (before entering the desktop), otherwise the computer may not start normally.
