As sudden as it happened, I would guess something happened to your partition table. There are some tools available that say they can fix that, I'm unsure of how they work as I've never come across that problem myself. Here's something I found on Google: https://www.cgsecurity.org/wiki/TestDisk.
As far as your RAID question goes, I think what you'd be looking at is RAID 1, which is just mirroring (no striping). There are a number of RAID-capable NAS (Network Attached Storage), or you could probably buy a RAID card that would plug into a PCI slot in your computer and then your drives would plug into the RAID card, of course going that route I think you could have a similar problem in the future, it'd just do it to two drives at the same time.
