What does the message "AVISO" ( see attached screen print) that appears after the defraggling process means?

Try clicking the AVISO tab. It seems S.M.A.R.T. is reporting something may be bad with the hard drive.

Pulsa en la pestaña AVISO. Parece que S.M.A.R.T. está informando de que algo puede estar mal con el disco duro.
