I need to find out what specific types of media the drive supports. For instance I need to know if the drive supports CD-R or CD+R or CD-RW or DVD-R etc. Any help to point me in the right direction would be greatly appreciated. Steve

True...but that enumeration does not (at least as far as I can tell) differentiate between CD-R and CD+R or DVD-R and DVD+R It does differentiate between CDR and CDRW or DVDR and DVDRW but I need more than that. The relevant portion of the enumeration CD_ROM \\ Opt_Disk - CD CD_R \\ Opt_Disk - CD-Recordable (Write Once) CD_RW \\ Opt_Disk - CD-Rewriteable DVD_ROM \\ Opt_Disk - DVD-ROM DVD_R \\ Opt_Disk - DVD-Recordable (Write Once) DVD_RW \\ Opt_Disk - DVD-Rewriteable If I am missing something please tell me which members of this enumeration provide that information. Thanks, Steve
