HDD problem - hda: status timeout: status=0xd0 { Busy }

[jabr at blu.org (John Abreau)]

I'm setting up an HP ProLiant DL140 G2 server, and I'm seeing some
serious performance degradation. The logs are filling up with the
following error:

Jun 23 14:40:20 shapieron kernel: hda: status timeout: status=0xd0 { Busy }
Jun 23 14:40:20 shapieron kernel:
Jun 23 14:40:20 shapieron kernel: ide: failed opcode was: unknown
Jun 23 14:40:20 shapieron kernel: hda: no DRQ after issuing WRITE
Jun 23 14:40:23 shapieron kernel: ide0: reset: success

The error appears at roughly 30-second intervals.

I found a suggestion through google to try fiddling with hdparm,
particularly with the -m option. hdparm -I showed
R/W multiple sector transfer: Max = 16, so I tried
"hdparm -m16 /dev/hda", but this didn't fix the problem.

I'm looking at the hdparm man page now, but I can't figure out
what to try next. Any ideas?

Here's the output of "hdparm -I /dev/hda". This is an 80gb sata drive.
All I've done on the machine so far is install CentOS 4.3.
