Hi, the "Copy" task yields very interesting results: A closed CD-R and a closed CD-RW which were written by write type SAO don't spoil the drive. Inserting a closed TAO CD-RW (burnt by Brasero) spoils the drive. This spoiling is in effect already when the dialog window of Brasero asks me to

Hi, the spoiled ASUS drive does not seem to be a direct result of an attempt to read audio CD sectors from a data CD. The drive is rather too tolerant in that aspect. The MMC-5 specs say that it should throw error 5,64,00 "ILLEGAL MODE FOR THIS TRACK", but the drive doesn't. It does not go bad
