why didn't K3B tell me I was trying to erase a CD-R?
 

I tried to erase a CD-R in K3B, having mistakenly grabbed it instead of the CD-RW I meant to erase. Nothing happened to the CD-R, of course. I'm just wondering why K3B just eventually claimed that the CD was successfully erased, rather then letting me know it was unerasable. Does K3B not bother to notice the difference?

well it does give you a message but you have to spot it at the start of the burn attempt
