This is frustrating. We can't tell from either the packaging, or from the product description, or anywhere else; whether these are supposed to work with LVD or not. I'm guessing that they're not, or they'd advertise it. > You will probably need a converter that is meant for LVD devices rather > in order to get the drive to kick into LVD mode. Finding these is like buying electronics from the Amish. The product descriptions don't really tell you, and the service people don't seem to know. Do you know specifically of any products that we can get that *will* work?
