DriveStatusError problem in Linux

I use CentOS, While Linux is booting, I found these warning

hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hda: drive_cmd: error=0x04 { DriveStatusError }


These warning come from smartd (Self Monitor and Reporting Technology Daemon)
If you don't like these warning, close the daemon (smartd).

I notice most who have face the problem use Western HDD. May Western HDD not support some commands. (just guess :/)

Anywhere, it just warning :D
