24 hours of Googling and I still have no idea what "559" means, and I haven't gotten a response here. Me thinks that isn't good.
So, I'm wondering if I should maybe proceed in a different fashion. Would be a good idea to scrap backing up to DVD-R and instead backup to a HDD and use a USB-loader? Or if a backup fails on DVD-R is it assured that USB is going to result in failure as well? I don't mind buying a big azz drive, but I don't want to do it without being reasonably confident that it's WORTH trying. I know sometimes people are like, "Rather than ask, just try it, a-hole," but in this case -- before I go drop some dollars on a USB hard drive, and ignore my 2 spindles of 100 blank DVD-Rs I want to know if I'm just "killing time" or if I have a legitimate shot at success.
