4) Is your motherboard set to use AHCI for the SATA (ICH7) controller?
There's reports that SATA300 is only available/used on some controllers
when AHCI is used.
I dont know. I could not find such a similar option on BIOS, so I dont
know how to check it. Is it possible to be checked from system?

Just to let everyone know, for me this "AHCI" thing made the whole
difference. On BIOS there were some options to be combined with AHCI,
and doing the right combination made the disk get controlled as
SATA300.

Thank you veryone, specially Jeremy Chadwick for the valuable inputs.



I cannot seem to find any relevant option for this on my Intel
946GZIS Mobo - and I just installed the very latest driver.
During boot, I get this:

atapci1: <Intel ICH7 SATA300 controller> port 0x20c8-0x20cf,0x20ec-0x20ef,0x20c0-0x20c7,0x20e8-0x20eb,0x20a0-0x20af mem 0x90204000-0x902043ff irq 19 at device 31.2 on pci0

Then I see this:

ad4: 238475MB <WDC WD2500JS-00NCB1 10.02E02> at ata2-master SATA150


However, I see this after the system comes up:

$ atacontrol cap ad4

So .... does the fact that "Protocol Serial ATA II" is reported mean the
drive is actually running as SATA 300 regardless of what was reported
during boot?

And, yes, I have tried the speed limiting jumper on the back of the
drive both on- and off- with no difference...
