Although the U disk is a Plug and Play device, support hot-swappable, but this does not mean that it can be arbitrarily unplugged, if unplugged improperly, it may cause the U disk damage, causing unnecessary losses. What problems should you pay attention to when you plug the USB stick? After summing up, there are about 3 aspects of the following.
Note: After inserting a USB stick, do not unplug it immediately. In particular, do not repeatedly fast plug and unplug, because the operating system needs a certain amount of reaction time, Plug and unplug the interval when asked best in more than 5 seconds. Do not insert it immediately after you unplug it, wait 5 seconds before inserting it.
Note Two: Do not unplug the USB flash drive when the indicator light is on. The light and shade, flashing, etc. all reflect the different states of the U-disk, generally speaking, the indicator light can not unplug the U disk. In Windows 7, you can unplug the U-disk only if the light is off. For the U-disk without the indicator light, wait for a while to pull out after the read and write operation, so it is more safe. The USB flash drive in Windows 7 is always on, this is because the win 7 added to the USB device detection function, as long as there is data traffic, the indicator light will blink, to deactivate the device, and then pull out the U disk, it will be more secure. The deactivation method is: Under Windows7, the USB device icon appears in the taskbar after you insert the USB drive, and the icon opens to display the U-disk device in the list, where you can choose to deactivate the device.
Note Three: note the direction. Encountered the situation can not be inserted, do not force, to see if the direction is wrong, often in a different direction can solve the problem.
