urca, scaricato lo smartdefender di IBM mi dice:

Primary Master (IBM-DTLA-307030)
Self-test routine completed with a SMART alert error!
Any drive reporting a SMART failure should be considered likely to fail at any time. (e qua mi sto gia’ toccando). You should back up your data on any such drive as soon as possible. Contact your computer or hard drive vendor to obtain return information

meno male che mi sembra che la garanzia di IBM duri 3 anni…
