Hello....

I'm hoping someone will know what causes this.

I did a trade with someone known as a very good trader and half of the discs he sent to me were "blank" when I tried them on my players. I copied them in my duplicator however and the copies play fine. I can now use the ones he sent as "blanks" and what I recorded on them plays fine.

What causes this?? I've done tons of trades and it's not my players.

Please post or email me if you know and thanks for any help/info!

could they be RW (rewritable) disks?

your player may not be able to read them if they were finalized on a different writer, but you'd still be able to write on them.
