Spot Signs of SATA Performance Degradation on Cougar Point P67/H67 Chipsets

Apparently there's a "slim" chance of users actually being affected by the recently-discovered chipset design error plaguing Intel's Cougar Point 6-series chipsets that drive the SandyBridge processors. Intel pegs this at 5% performance degradation caused due to data transfer errors over a period of 3 years. Users of Romanian tech community Lab 501 found out a way of detecting if your hard drives connected to the damage-prone SATA ports are already showing signs of errors.

To do so, you need the HD Tune Pro software, you can try out the Pro version. Select a hard drive connected to the damage-prone SATA 3 Gb/s port, click on the "Health" tab. HD Tune checks out various self-diagnostic parameters of the drive, including SMART values. A drive connected to an affected port should fail a number of tests as shown in the screenshot below. As a stopgap solution, you can connect the drive to one of the SATA 6 Gb/s ports available. Most motherboards should have 2 internal 6 Gb/s ports, some have additional 6 Gb/s ports driven by 3rd party controllers. It's advisable to use ports of those controllers. This stopgap fix should pull you through till April-May, when motherboard vendors are expected to have motherboards with B3 revision of the Cougar Point chipset. You can then claim replacement of your board under warranty.
