Gigabyte released a free software utility that works on any motherboard (of any brand) that uses Intel's defect-prone 6-series chipsets (such as P67, H67), and checks if the installed hard drives are connected to defective SATA ports, or whether the board is prone to defects at all. According to Intel, it's not that every 6-series motherboard out there carries defective ports, and that whatever defects there may be, would only surface over time. Some users, however, are beginning to see signs of defects right away. The 6 Series SATA Check utility from Gigabyte is the company's contribution to resolving what is a chronic market-wide error affecting all motherboard vendors selling socket LGA1155 motherboards.
