The internal SATA port is connected to one of these: http://www.cru-dataport.com/products/DataPort-10.php I considered that this could be a source of noise and interference, however: - I've got a few of these devices hooked up to intel-based AHCI controllers, without any (hotplug) problems whatsoever. The 6121 is the only one with problems. - I only have problems on hotplug, never any CRC errors while actually using the drive. - If it was power/connection/cable problems, I presumed the problems would persist even after reloading the ahci module. Could it be because the drive hasn't been fully spun up yet when the key is turned and the power/sata is plugged in? Thanks, -- Mourad DC
