Will it be damaged if you pull out the USB disk directly?

3. A widely circulated statement on the Internet is that it will cause damage to the USB disk socket on the computer and may burn the circuit board near the interface.

Precautions when using U disk:

1. U disk generally has a write-protect switch, but it should be switched before the U disk is inserted into the computer interface. Do not switch 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.
