How long should it take for a book to be transferred via USB to the Reader? That "do not disconnect" message has been showing for several hours now, after I transferred 3 not-very-large books to it. This seems a very long time to be transferring files -- I could move large photos or other large files to/from connecting devices via USB in just a few minutes. It doesn't seem reasonable to me that I would have to wait for hours for a data transfer to be completed. Can anyone tell me what I should expect as a reasonable data transfer time, and if several hours is unreasonably long, am I safe to disconnect the USB anyway?
