Am getting an error message that comes up consistently saying that I need to use only certified 2x or 4x CD-R or CD-RWs in the drive. The burner is model HP 8200 USB. I have CD-Rs that are rated at 1x - 32x, and they don't work. I went to Best Buy and they don't even carry 4x CD-Rs. I don't use CD-RWs very often, as I use my other burner for backups - and was trying to get another burner to use with my older laptop, which I use alot .
