For the last couple of days, I've been getting these errors in Toast whenever I try to burn disks, each one in a series a few seconds apart. The last appears twice, then I'm told simply that Toast failed to burn. I can try a burn in Disk Utility if necessary, but I've already wasted about $8 of disks, so I'm kinda loathe to destroy any more. What do you think? I'm pretty sure it's a hardware problem, but if I don't have to take it into the shop, I'd rather not.
