Of course the drive stops responding at this point.I can also hear the disk RPM changing after this happens... sounds like it speeds up, then cuts the motor off for a moment, then comes back on..
Check your power supply. This happens when the 12 V line is weak or has excessive ripple.
From these power dropouts your drive may collect some bad blocks, but this can be healed by reformatting.
Best regards
