[QUOTE=aumortis;2151593]Small update: at first I thought that those DVDs are defected because I found old blank DVD-R by TDK and it’s detected properly. My friend’s Samsung drive detects both without a problem though…[/QUOTE]
Well FWIW the ‘old’ TDK could very well be a different disc (a different manufacturer) than the ‘new’. TDK at one time actually made discs… not anymore. It is also not unusual for older drives to have problems with newer media.
I always use TYG02 discs (Taiyo Yuden 8X Premium Line). They basically work in almost ever burner, old and new, and are great for those folks afraid of firmware updates.
