I think that that would still be handled by the disk's controller.
SATA is just like ethernet. You have a PHYsical layer -- the SATA ports
on each side of the links -- that must be managed. The SATA controller
(really the SATA PHY) performs error correction per the SATA specification.
Yes, I see. The serial link has error correction. But it isn't
involved in correction of disk errors.
