Thanks for all the useful information.  I will try installing this in
a //e I have set up.  I'll take out the 3.5" apple superdrive
controller that is hooked up to a couple of m106 3.5" drives and try
the UDC controller card with the "laser" 3.5" drive.  I don't want to
risk the superdrive controller card with this "laser" drive....just in
case....  again....thanks for the help to all!!!!  ;)
