Matias's problem doesn't have anything to do with spurious completion.
PHY RDY changed and HSM violation are completely different error conditions.

I think either the harddrive or power supply is dying.  smartctl -a
might show something but I'm not too hopeful.  The surest way is to
connect the drive to a different PSU and see whether the problem goes
away but if all other drives on the system is fine, I would just throw
away the harddrive.

Thanks.
