I have two ATI VGA Wonder cards, one is about 10 months older than the
other.  The newer one is called a VGA1024 and has a much thinner manual
which does not include any phone numbers for ATI.  My problem is when
the hard disk is accessed, the video receives interference like a burst
of RF.  No screen data is lost, it just makes the screen fuzzy for the
duration of the access.  It is only the newer card that has the problem.
I have a second machine and have determined this by swapping cards, etc.
The drives are Seagate ST277R-1 and the controllers are Adaptec and
Western Digital.  Any ideas?
