trurl - thanks for the warning. I tried to research this a bit (see topics below). If I understand it, then my specific case of exposing the root of the cache drive (unpooled and not otherwise used as part of the array) should be OK. I'm not trying to manually copy/move files from the cache to the array or to individual disks. I think my main use cases are: more easily access log files on cache/appdata or back up files residing on cache (e.g., copy from cache to USB drive connected to a Mac/PC). Unless I'm missing something, then this should be a reasonably safe. Thanks
[And if you were referencing my screen shot where it showed check boxes for Disk 1 & Disk 2, then I will uncheck those as long as I don't lose access to the root of cache. It's just that I thought I had Enable disk and User shares set to Yes earlier when I couldn't map cache. That's why I ended up checking Disk 1 and 2. I can't stop the array for a while since it's busy redoing Plex, Crashplan, etc...]
