Are you sure? I see no hard disk attached there :-?

This is my output ("ata1" is where my first sata disk is connected):

sm01@stt008:~$ dmesg | grep -i ata1 
[    1.845459] ata1: SATA max UDMA/133 abar m2048@0xdc627000 port 0xdc627100 irq 1277
[    2.388162] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[    2.428872] ata1.00: ATA-8: ST3250310NS, SN06, max UDMA/133
                               ^^^^^^^^^^^

[    2.434697] ata1.00: 488397168 sectors, multi 0: LBA48 NCQ (depth 31/32)
[    2.475931] ata1.00: configured for UDMA/133

Despite the ata2 port is "up", I wonder why there's no device listed.

So it seems :-?

You should clear the buffer cache first but still, those values seem a 
bit conservative for sata 6 hard disk (caviar black) with sata 6 
controller.
