Subject: SATA HDD seen at UDMA33

Hello,

I have a SATA HDD (http://www.samsung.com/Products/HardDiskDrive/SpinpointPSeries/HardDiskDrive_SpinpointPSeries_SP2504C.asp) in my server but it shows:

ad4: 238475MB <SAMSUNG SP2504C VT100-50> at ata2-master UDMA33

I've seen here http://monkey.org/freebsd/archive/freebsd-stable/200705/msg00393.html that it's detected at ata2-master SATA150 

Can anyone please tell me why it's seen at UDMA33 and how can I fix this so it's detected correctly? I'm running FreeBSD 6.2.

Thank you,
Alin
