Seagate and WDC both ship SATA300 drives with a SATA150-limiting jumper
on them. It's documented on the drive itself, and in the manufacturing
manuals. Both companies do this as a precaution; there are some buggy
chipsets out there which claim to support SATA300 but then break badly
when utilising it. This is why the jumper's set to SATA150 by default.
Chances are your drives have the jumper limiting the drive to SATA150.
I have the same situation here, but not the same hardware:
atapci0: <Intel ICH7 SATA300 controller> port
0xe8200000-0xe82003ff irq 19 at device 31.2 on pci0
ad0: 76319MB <SAMSUNG HD080HJ ZH100-47> at ata0-master SATA150
This drive is withtout the jumper, which according to the manual means
it should operate as SATA300 (while with jumper plugged, it is limited
to SATA150). But it is only controlled as SATA150.
So, chances are my disc also have some problem?
