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... -- ---------------------------------------------------------------------------- Tim Daneliuk tundra@tundraware.com PGP Key: http://www.tundraware.com/PGP/
