  (1) Check appearance

  After you get the floppy disk, you first need to see if the floppy disk shell is well processed, and then pull the metal or plastic sheet apart by hand, and observe the surface of the disc in a bright place: the surface of a good quality disc is smooth, uniform, and free of scratches. There are no marks or mildew spots; if you can see diagonal lines or countless obvious circles, the quality is poor; if you can see obvious defects and damage, this floppy disk is almost unusable.
