Is the drive connected to an "nVidia nForce MCP55 SATA300 controller"? I have two machines with on-board MCP55 controllers. One of them works perfectly, the other causes silent data corruption (each time I run a zpool scrub it finds new checksum errors). If you also have an MCP55 controller then maybe this is related. /Daniel Eriksson
