Hmm, are you really sure that this is 3Gbps mode related ? I'm wondering about that as the problem is there no matter if the 1.5Gbps jumper is set on the 7200.10 disks or not. Also I retested your older sata_promise 1.5Gbps speed limit patch and it did not fix the problem. This is really strange! I've now connected the problematic two 7200.10 disks into Via VT6420 controller and the problem has been fixed for me (for now). It would be great to figure out what is the actual problem here though ...
