My Sony 40X12X48 CDRW works fine when looking at data or listening to music, but when trying to make data backups or music cd's I get messages saying: "there are no supported CD-recorders available"; "no CD recorders were found"; "Creator API returns failure"; and when reinstalling the Roxio Easy CD Creator 5 Platinum, a message states, "no supported drives found". My OS is windows XP-Pro. Many thanks to any respondents.
