So, yes, the external drive is where we are live ingesting our images to. Our iMac doesn't have enough space internally to store there while we are editing.
The issue today is the error deleting from the Volumes/ftp/ftp/scotthh2/ in PM6 while in Live Ingest. It absolutely will not delete them. But in PM5 it absolutely does. So, there is something fundamentally different going on between 5 & 6. Yes, the directory exists, it's possible ftp is in there twice, I'd have to look when I get back to the rink.
We started last nights game live ingesting with PM6 from the FTP. The errors started showing up immediately. We switched back to PM5 and problems go away.
