Im using an old sony dvd burner, and lately nero has been having alot of 'disk write errors' when burning cd's/dvd's. Is there a program i can use to test my burner?..or the other possiblity i can think of is that the cd's and dvd's im using..i bought from future shop on boxing day for like 5$ a spindle. soo im not sure if they were just trying to get ride of some defective crap.
