Also the fact that the drive is showing up as /dev/hda instead of /dev/sda means that you are not using the best driver for the hard drive. Go into the bios and try either native mode to serial ATA or SATA AHCI enable. You might need to rebuild the initrd from a rescue disk after you boot.
native mode to serial ATA
Did that. Now it shows up as sda again. I no longer get the errors either but I get this now.
[root@server log]# hdparm -i /dev/sda
/dev/sda: HDIO_GET_IDENTITY failed: Inappropriate ioctl for device
Smartd also complains on boot up.
Any ideas?
