Smartd is having a fit about Seek_Error_Rate.  Like you said from
looking at a few google searches this is normal with Seagate drives
and does not mean they will fail.

I think I may be close to having most issues straightened out with
this messy upgrade.  My iostats are still 3 times higher then prior to
upgrade though.  Is it perhaps an issue that Centos 4.7 does not
support the Intel ICH9R SATA controller very well?

Thanks.
