Linkstation LS220D - Storage and iTunes Art questions

[lister110]

Hi everyone, this is my first post and my first time using a NAS so please bear with me.

I have just gone through the procedure of getting the drive up and running. I have a 6T (2x3) drive which Im preparing and testing for various things. I have a couple of questions someone could hopefully help me with.

1. At the moment I have one drive mirroring the other. I would like to setup some folders or partitioned drives so I can allocate a certain amount too/how much is available. I have already setup shared folders which is great but I'd like to see how much space is being used by say the media drive or Work drive on the fly (like when you see an external drive at the bottom). How do I do this?

2. Itunes server has been activated. I setup an iTunes lib directly onto the drive (media folder). And have gone into my own local iTunes and selected the shared server. But for some reason I can see any album art, only the track art which is in the mp3. How do I get the art to show up in iTunes (if possible).

3. My network is made up of just Macs / iPads / iPhones / Epson Printer the drives are default to FAT, I move around large photoshop files, should I re-format these to Mac Journalled?

thanks
