When we finish using the USB flash disk, we will click the safe pop-up button. Why can't we just unplug it? There's knowledge in it. Young guys who don't understand girls need to figure it out.
In fact, whether the U-disk should be ejected safely or not affects two places. A computer and a USB stick.
Let's talk about the transmission principle of the U disk first. A normal U disk has four pins, which are generally long on both sides and short in the middle. When we transfer files, we usually use two long pins for power supply and short pins for transmission. And our normal safe pop-up is actually to disconnect the transmission first and then unplug and disconnect the power supply. So at this time, you should understand the meaning of safe pop-up. The safe eject just stops the transmission of our USB flash disk.
However, some people may ask why sometimes the USB flash disk clearly shows that the transmission is completed. But the security pop-up still can't pop out? Actually, the U disk is very ingenious. In order to highlight its fast transmission speed, many u disks write to the U disk secretly in the cache when the system prompts to complete. Therefore, the system prompts to complete or cannot pop up. So pop up this option is to ensure that the transmission is completed.
See here you should understand that the safe eject is to ensure that the file transfer is completed. If the file is not safe eject, unplug the U disk and it will not damage the file. And if you want to say why your U disk is broken without a safe eject and insert record, that may be the reason why your U disk quality is not good. If you still don't trust to form the habit of safe pop-up, it's also good, after all, this way to ensure our file security is not. Because some files are more precious than the U disk!
