Do you have any experience in working with 500Gb or more SATA drive?
Can you provide what ATA chipset this drive is connected to? The
drive appears to be associated with ata2. The following may suffice,
for example:
$ dmesg | grep ata2
ata2: <ATA channel 0> on atapci1
ad4: 114473MB <Seagate ST3120827AS 3.42> at ata2-master SATA150
$ dmesg | grep atapci1
atapci1: <nVidia nForce CK804 SATA300 controller> port
0x9f0-0x9f7,0xbf0-0xbf3,0x970-0x977,0xb70-0xb73,0xd800-0xd80f mem
0xd3002000-0xd3002fff irq 23 at device 7.0 on pci0
ata2: <ATA channel 0> on atapci1
ata3: <ATA channel 1> on atapci1
Additionally, please provide the output of `vmstat -i` to see
if there's any shared interrupts with the ATA controller.
Yes, of course:
%dmesg | grep ata2
ata2: <ATA channel 0> on atapci0
ad4: 476940MB <WDC WD5000KS-00MNB0 06.02E06> at ata2-master SATA150
%dmesg | grep atapci0
atapci0: <SiI 3112 SATA150 controller> port
0xdc00-0xdc07,0xd480-0xd483,0xd400-0xd407,0xd080-0xd083,0xd000-0xd00f mem
0xff8fec00-0xff8fedff irq 22 at device 1.0 on pci1
ata2: <ATA channel 0> on atapci0
ata3: <ATA channel 1> on atapci0
%vmstat -i
