Recently, I've had a 100% failure rate with my LiteOn SOHW-812S. I've tried writing to DVD-R CMC Magnetics AE1 media (yeah, I know, terrible) and DVD+R Prodisc R03 media (average quality).
Only when I try writing to a Verbatim DVD+RW, the write result is fine.
I'm trying to decide if it is my drive (about a year old) or my media that is to blame.
Are there any tests I can do to verify if it is my drive?
