How old, and what color are your sata cables? There is something in the dye used for "hot red" cables that converts the copper of the conductors into a brown rust like powder which of coarse is a very poor conductor. Reboot, put a tail on the syslog, and touch the cable so it is moved a bit. If it blows up the syslog with more such messages, replace the cable, but replace it with any color but red..
