I was burning some backup data on a YUDEN000T02 @ 8x the other day, and roughly half-way through, I got a buffer underrun. I suspect it was because my hard drive couldn't keep up, but regardless, Burn-Proof was enabled and it continued burning after the buffer recovered, and the disc verified fine (using ImgBurn).
So my question is: is this disc safe for archival? Or should it be re-burned to be on the safe side? I don't have any means of producing an accurate scan of the disc, so just a general answer will do.
