Ok, I have a 40x CD-Rom and a 8x4x32 CD-RW. My cdrom works fine, but my cdrw only reads certain cds. It will read my burned music cd, but not a store bought cd. And it will not read burned data cds. This is very strange and I hope someone here will be able to enlighten me. I am running WinXP on a Duron 800, with 256 ram and a 20 gig HD. Any help will be greatly appreciated.
