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
Protocol Serial ATA II
device model WDC WD2500JS-00NCB1
serial number WD-WCANKD870194
firmware revision 10.02E02
cylinders 16383
heads 16
sectors/track 63
lba supported 268435455 sectors
lba48 supported 488397168 sectors
dma supported
overlap not supported
Feature Support Enable Value Vendor
write cache yes yes
read ahead yes yes
Native Command Queuing (NCQ) yes - 31/0x1F
Tagged Command Queuing (TCQ) no no 31/0x1F
SMART yes yes
microcode download yes yes
security yes no
power management yes yes
advanced power management no no 0/0x00
automatic acoustic management yes no 254/0xFE 128/0x80
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...
