kernel: ata1: error=0x84 \{ DriveStatusError BadCRC }

I've upgraded to VMware-server-1.0.0-27828 on Fedora Core 5 with kernel kernel-smp-2.6.17-1.2139_FC5 everything seems to be working ok, but I keep getting the messages on my console and in /var/log/messages. Anybody else seeing this behavior? Does anybody know what to do about it? Is this harmful?
