I get the same thing.  I've got a Western Digital 6.4 gig ATA 33 that is on an
old AMD K6 200mhz processor/mobo (which doesn't support any sort of UDMA).  Of
course, the HD is going on 5 years old now.  I haven't had any problems (yet)
besides an occasional hang on bootup when it tries to mount the partitions. 
Someone earlier said that this was a possible indicator of a failing drive.
