My CD-RW-rom suddenly stoped recognizing CD-RW's. It reads and records CD-R's just fine, but will not work with CD-RW's anymore. I don't know at what point it stoped recognizing them, but when I needed to record something I couldn't. I don't know if it's hardware problem or software. My DVD-rom will read the same CD-RW's just fine! I'm running WinXP Pro SP2. Model number: SONY CD-RW CRX215E5. If anyone has any suggestions on this, I will be grateful.
