I recently tried to copiy my cds on a HiMD MD using the MD Simple burner (MSB)software. I was using 45KPS and managed to get about 13 CDs on one disc. While copying my 14th cd my MSB generated a message saying my tracks were being used somewhere else and it couldn't copy them. So, I exited the program. I tried to play the music I had already copied and I got a message saying that I "Cannot Record or Play." Keep in mind that I had been able to play music before and tested it after each album. Has anyone encountered this before? The disc seems useless now. I can't read it so I can't even erase it and start from scratch.
