I have a test machine with FreeBSD-5.3 RC2.  It only has 2 drives (ATA). 
  I am seeing this error (intermittently):

ad0: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=3239915
ad0: FAILURE - WRITE_DMA timed out

Though the system seems to otherwise be working just fine.

This used to be a Windows/XP system for a long time, and I never had any 
trouble.  So I wonder what the above can be indicative of (ie: bad 
cabling, or?).


Thanks.
