Thanks for all the info 14fritz. When I called Imation about my 12x8x32 drive, I was told it's a rebadged Acer 1208A. The model number is 1208A-062. The box actually says "No Buffer Under Run", but doesn't say how. Must be seamless link like you said.
The manual has little tips and tricks you can use to prevent underruns. Why, if it has the technology to make that a thing of the past, would they offer this info? It's not easy to be up on all this stuff when companies play these games with it's customers. That's why I have Max Confusion! 😕
