This is a hardware error on SATA bus. Could be cable, SATA controller
on the motherboard, or the electronics on the drive.
The only way to test it is by exclusion: replace the cable, see if
anything changes. Then either replace the disk or put this disk into
another PC, depending on what you have available. See if if the
problem follows the disk or the motherboard. Could also be bad power
supply, if you have a spare supply you can plug it in (don't even have
to install it, just connect the cables).
