My Tascam CD-RW750 everytime I put a memorex CD-RW in the drive, it just comes up and says NOW OPC, but works fine when I put CD-R in it. I need the cd-rw so If I make mistakes I can erase it. Can't erase cd-r. Please help. I don't know what's wrong. Thanks for any help on this. And after it says NOW OPC it then says disk error. Sometimes it will eject, and sometime it won't even come out, I have to turn unit off then back on to eject it. Please help. But it works fine when I just use regular CD-R disk.
