I’m having a problem with my DVD/CD read drive. In the past month it has stopped recognizing any disk in it. My two drives are D: Samsung DVD-ROM SD 616E (Read drive) and E: NEC DVD_RW ND-3550A (Burner drive). My DVD software for reading DVDs are Real Play, Windows Media Player, Media Center 2004 (uses Sonic), MCtr, Magix Media Manager, Power DVD, Video LAN VLC Media Player, Sonic Cine Player and Quick Time Player. All DVDs and CDs play perfectly using my E Drive with any of the software mentioned but when in the D drive, the following message comes up “Please insert disk into drive D”. I’ve tried replacing Drive D with a brand new drive from CompUSA but the results haven’t changed. Ripping and burning are not a problem using one drive but I'd like to get both drives up and running. Is there anyone who can help solve my problem?
