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.
