Ooooh I didn't know about this. Thanks for the tipoff. I'm actually gonna look into this! I am so screwed if any of my drives die. I - at the time of getting them - couldn't afford backups. I can afford to get dvds though! That's a good idea that dumb me hadn't thought about - backing up onto disc. See, what format to go for is a problem for me anyways as I've got several 4tb drives - EACH of which is full or within a couple gigabytes (less than 100) of being full. I'd just go for another larger drive but....at what point do you go "hold up"
