RCA duel cd recorder

I have been copying cd’s that are 32x. I have 52x speed now and my machine says that it cannot read the disk. What is the difference as my computer will read either one. Thanks

Whether a drive can read your discs generally has little to do with the speed. The speed on a disc illustrates the alleged maximum writing speed you can reach using that disk. The 52x discs don’t contribute much of anything more. If they make your drive say it cannot read them, I suggest you go back to using the discs you know do work.
