What should I do if my VAIO computer does not recognize the floppy disk?

• Make sure the floppy disk is properly inserted in the USB floppy disk drive connected to your VAIO computer.

• Make sure the floppy disk is right-side up before inserting it into the drive.

• Make sure the USB floppy disk drive is securely connected to your VAIO computer.
  Remove the floppy disk from the drive and then insert it again.
