My HP CD-R/RW has never had any problems with the CD-R discs but HAS lost data when doing the Drag&Drop funtion on the CD-RW's. My version of Direct-CD is about a year old though. btw - Adaptec also has a free utility at their site that will allow any (high speed) CD-ROM drive to read their CD-RWs. Being able to copy directly from the CD-ROM drive to the burner has sure made my file management a lot faster & easier.
