I am coming to conclusion that CentOS 4.7 does not support the Intel ICH9R SATA controller very well. My disk I/O is really slowing down as well. Any solutions besides replacing motherboard to fix it?
Thanks.

I upgraded my Centos 4.7 server last night. Switched from a cheaper 50$ asus motherboard to a Supermicro motherboard. I also, using dd, copied entire 500g SATA seagate drive to new 500g SATA seagate drive so as to have two copies in case something went wrong.
Anyway, now I keep getting this error:
Nov 21 06:08:33 server kernel: hda: status timeout: status=0xd0 { Busy } Nov 21 06:08:33 server kernel: Nov 21 06:08:33 server kernel: ide: failed opcode was: unknown Nov 21 06:08:33 server kernel: hda: no DRQ after issuing WRITE Nov 21 06:08:34 server kernel: ide0: reset: success
Found one website that told me too try hdparm -i to see whats up:
/dev/hda:
Model=ST3500320AS, FwRev=SD15, SerialNo= Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4 BuffType=unknown, BuffSize=0kB, MaxMultSect=16, MultSect=off CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 AdvancedPM=no WriteCache=enabled Drive conforms to: unknown:

So from recommendation on website I did this to match MaxMultiSect:
hdparm -m16 /dev/hda
then tried this to turn MultSect off:
hdparm -m0 /dev/hda
Still getting error. The Supermicro MBD-X7SBL-LN1-O motherboard has basically all defaults set in bios.
Any ideas? Thanks.
