slight hiccup. I traded my old NAS enclosure for 4TB (2x 2TB) of storage via craigslist. Did some research, and while they are usable with unraid, it takes a bunch of effort. So these two drives are now in my media front end with a fresh install of windows 7 and all of my various media delivery apps. Copying all of my data locally and will begin the process of building my unraid box over the next few months.
in the meantime, i have 3.5TB of usable storage space, albeit unprotected from drive failure. I'm not too worried about it, since this is not my long term solution.
