Hi Jack,
It works!! Finally got it going. I only copied music files onto the drive, so that's all the Mini could copy. I haven't looked at all the files yet, but a fair amount have the covert art. I need to study all that and I believe any tagging will need to be done on the external drive and copied onto the Mini. I think I'll be able to handle many if not most of the issues that pop up after this. Thanks to you and all for the help and comments.
Nick
