It might be for the best Ricky, it's a hell of a risk to take otherwise. I always play safe with data and different software!
Seriously though, some of you folks really should look into UnRAID as a way of making your life easier. Basically, it's this:
1. Take one old PC, with lots of space for drives and lots of SATA connectors. Everything else is secondary (CPU, RAM etc)
2. Get two drives, one of them as big as the biggest drive you'll ever want to fit. That one is the parity drive, and does not hold data.
3. Install drives, then install UnRAID software via USB and boot.
4. Set it all up (takes about an hour unless you want to preclear the drives).
5. Transfer stuff onto it.
That's it. You can add as many drives as you want as long as they're not bigger than the parity drive. If one of the drives fails, you simply replace it with a blank one and the parity drive rebuilds it for you. It's such a simple solution, as long as you're prepared to spend an hour or so learning the basics of linux, or even just follow the guides that are out there word for word like I did. It's not as redundant as a proper RAID solution, but it does a bloody good job of pretending it is for much less. If anybody wants to know more, I'll let you know about my setup and what I did (and the challenges I overcame) as a complete NAS/linux noob.
