The 1 TB "drive" is actually a flash memory card. I think this has something to do with the type of partition, but it is a standard GUID partitioned as exFAT, which I have used with many d]external drives on the BDP-2 and previously ono the BDP-1. For some reason this is a bad combination this time. Chris is looking at it, but I fear that I will have to start all over, since the system doesn't even "see" the drive as being connected.
Thanks for your input.
