i've been using it a day and so far it's ruined 3 out of 5 discs, the first time i use it it gets stuck on 2% and then doesn't do anything apart from making the disk unusable again, the second time i use it (after i've had to reset the computer) it sometimes works, but this time it didn't, it said it had finished and it had done 18 tracks, but the last 2 can't be read and it crashes whatever program it's running on! Is there any burning software out there that works?
