With the same cables? Not that I want to use cables as a scapegoat, but in this case it seems applicable. > Unfortunately the drives does not have a jumper for setting SATA-150 > speed (they are Samsung 1 TB drives), and trying to force the drives to > SATA-150 speed with the "patch" provided by the manufacturer does not > seem to work (the drives still negotiate SATA-300 speed).

Can you provide "atacontrol cap" output for one of the drives? I know in the case of Maxtor drives, there is a bug that exists in one of their disk firmwares which causes silent data corruption and/or SATA bus lockups when NCQ is used on nForce 4 chipsets. Maxtor provides a firmware update which fixes the bug. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
