I was trying to copy a CD on my computer, inserted the original into one drive, inserted a blank CDR onto the other, and it started going. About 60% of it was done and then it said "Medium error" and stopped; the disc was never fully copied. I tried Verbatim CDR and Memorex CDR, and my burner is a Philips 8701 (FW: 5D24). I havent had problems with my drive since I got it a month ago but now all of a sudden I am. Any suggestions would be great; thanks.
