Blu Ray DVD burning on Sequoia - icon for drive appears as iCloud
I've just got a Verbatim USB Blu Ray DVD drive, and whenever I put a blank BD-R DL in, the Finder icon appears as an iCloud device in the sidebar, and dragging anything over seems to make it into an Alias. As BD-R DLs etc are pretty expensive, I don't want to click BURN on something that just doesn't look right and end up with an entire 50GB disk containing a 1KB symbolic link!
I've not been able to find any guides online for doing this - the Apple ones are pretty simplified and slightly at odds with what actually happens.
