Certainly. If you replace the disk, disk controller, and cable, the
errors will certainly go away. Doing one of those would be enough,
but I have no way to know which piece of hardware is causing the
problem. I recommend starting by just reseating the cable; in my
experience, this often clears up ATA bus problems.

Where do you see that? What else do you see with it?
