Hey I have an Adaptec 2903B PCI SCSI card and that is installed correctly. My burner is a Plextore 12/4/32 SCSI drive. Now my problem is, when ever I have the burner connected to the Card, the "Read On" light is on, but the drive is not recognized and I cannot open the tray. Now when I disconnect the drive from the card, I can open and close the tray. Anyone know what to do? BTW im running Win2k.
