I have a desktop PC with a DVD-ROM drive as "Master" on IDE cable. When I added a CD-RW drive, it would not recognize it if I install it as a Slave drive. But, if I switch it around, then it works (i.e. CD-RW as Master and DVD-ROM as Slave). In summary, DVD-ROM drive works as a Master or as a Slave; but the CD-RW drive works as a "Master" only. Does anybody know why? Is it possible to fix it such that I can install CD-RW drive as Slave? Thanks in adavnce.
