In Vero 4k+ Hard drive won't unmount

I wrote the above link instead of copying and pasting. It had the space after the /. If you look at the log, I think you would have to remove the space. Yes, I was playing a movie before I went backward all the way to the drive. I thought that I exited the movie. Was I wrong in thinking that. Also, I think that by not writing to the drive from the Vero, it is ok to exit without safely removing. Is this true?

Thanks, Don
