  • Your hard disk is most likely failing. – Tero Kilkanen Mar 06 '17 at 14:19
  • I think the real issue here is a faulty cable. – batistuta09 Mar 06 '17 at 15:16
  • @batistuta09 There isn't cable here, only a sata connector: [see picture](http://www.insidemylaptop.com/images/Lenovo-G570/upgrade-laptop-04.jpg) – cottonjoe Mar 06 '17 at 20:32
  • @TeroKilkanen smartctl test completed without errors. Hard disk seems OK. – cottonjoe Mar 06 '17 at 20:51
  • I have same thing on G510 Ubuntu 16.04. This had been happening for last 3-4 years with three different hard drives. (Linux seems to be able to cap the speed and work without problems, apart from showing that error message). BTW It freezes windows (by overloading disk queue). Probably connection between drive and motherboard. G510 doesn't have cable, it simply plugs into SATA socket (I just stopped using windows ;) ) – Dimitry K Dec 20 '18 at 21:43

This is caused by a faulty cable. I had the same issue, replaced the SATA cable and the error disappeared.
