My 3520 has been great, burning even the cheapest media well. Every once in a while it seems to hiccup and burn a coaster for no good reason, even on high quality media. It burns a very very small ring of data on the inner portion and aborts. The disc is unfortunately useless because of the corrupted data. Is there a way to avoid this phenomena? It happens with various media (TY, TDK, generic “ISO”, etc) averaging 1 out of every 20-40 burns.
I’m using the Liggy & Dee 2.u5 firmware. This has happened on prior firmware revisions too.
