Try CDBURNERXP. Erase the CDRW with that and record on the CDRW with that as a test. CDBURNERXP is free and won't interfere with the installed software.
my cd drive- Mitsumi cr-48xate suddenly doesn't recognize rewritable disks. It says there's no disk in drive. Device manager says the drive is working properly. Read only disks show up and run fine. Any ideas how to fix this?
