Those flashes may be Radio Frequency Interference.  If RFI is actually present,
try moving the drives and monitor further apart.  Also try better shielded
cable between the CoCo and the drives (or add shielding with aluminum foil
around the cable).  A metal drive case ought not need additional shielding but
you can always try.  One other thing to try is connecting the monitor's power
cable and the drives' power cable into separate circuits as interference can be
transmitted through your home's electrical system. For more info, you might
want to GO CEFORUM.
