For some reason I can’t get the drive to recognize any disk that is inserted. My BIOS and Windows XP recognize the drive which is operating as the only device on the primary ide channel (SCSI optical and hard drives). Device Manager indicates it is operating at Ultra DMA Mode 4. When a disk is inserted and I click on the drive letter I get a message to please insert a disk. I have tried DVD and CD disks both recorded and blanks.
Here is what is really strange. This is my second PX-716A. The first one did exactly the same thing. I connected my current PX-716A to another computer (Pentium 4 1.9GHz) and get the same results. The Plextor replaced a NEC-3500 which works perfectly on the same cable (80 pin), same Ide channel and same computer (Pentium 4 3.2 GHz Intel 875P chipset) with the same settings. What are the odds of getting two malfunctioning drives? What am I missing? Before I return this one I thought I would ask for suggections from the forum.
