How to Maintain USB:
1/ Never pull out the usb when its light flash quickly, it shows the usb is reading or writing data, it may cause hardware and data corruption if pull out in halfway.
2/ Do not close the relevant documents immediately after the completion of the relevant procedures, because usb light is still flashing, indicating that the program is not completely over, if pull out the usb immediately it is easy to destroy the backup.
3/ If the system hints "can not stop" , pls do not pull out the usb, or it will cause data loss.
4/ Note that the usb must placed in a dry environment, do not let the usb interface exposed to the air for long time , it will cause metal oxidation in surface and reduce the sensitivity of the interface
5/ Do not let usb inserted in the interface for long time, it easy to cause the interface aging and reduce the lifetime.
