That's link going down and up again.  Reseat/replace cable and see
whether the problem goes away.  Connecting the drive to different port
is also worth trying.  If none helps, the most likely cause is power.
After boot, record the result of 'smartctl -a' on the drive.  After the
above conditions occur, do the same and compare the result.  If
Start_Stop_Count increased, your power is having problem keeping the
drive spun up and if writes were in progress during such events, you'll
lose data.
