I have a Liteon 851 upgraded to cg4e. I have noticed that these CMC disks, unlike the Verbatim I usually use, when broken in half, seperate into layers rather than bending. Weird. If they are not properly bonded, even if they do burn OK, I would not expect them to last. In my drive the quality falls apart right at the end of the burn leading me to think that they can't cope with the full 4.7MG.
Ok, its a lost cause but it doesn't make it right. I still believe that when we pay our money we should know what we are getting. Don't we have a right to expect consistancy? I am told Burners Learn. All I ask is that the maker is clearly stated on the packaging.
Perhaps it might be an idea if these forums published a list of actual manufacturers.
