Recently a CDRW formatted to be able to "Drag and Drop" became unreadable. I tried to format another CDRW but got an error, at about the 20 minute mark, that said there was an error on the CDRW. I tried a few more CDRW's and got the same error around the same time. I am able to "Drag and Drop" to a few other CDRW's I have, but don't want to have these go bad if the CDRW drive is causing the problem. Could my CDRW drive have gone bad?
