I just got the 716UF at Best Buy. It is recognized by XP, but doesn’t read any discs. I tried DVDs, CDs, cd-roms, cd-rs, etc. The yellow light comes on for a second, but the disc is not acknowledged and doesn’t play. So I exchanged the drive for another one, and I had a guy in the computer department test the drive before I bought it. It worked fine on their PCs, read all discs he put in it. But on my PC it still doesn’t read any discs. So I installed Plextools by using another drive to load the install CD, and I’ve looked through there but don’t see anything that would prevent the drive from reading discs (and why would it be that way straight from the factory anyway?) Also, both drives have firmware 1.01. Didn’t help.
I’ve been through two new factory-sealed units, you so have to figure the problem is on my PC, not in the drives. Anyone know what could cause this? By the way, all other external drives work on my system, so it’s not a USB or firewire or cable issue. If no one can help, I’m gonna have to return this drive again and give up on it. There’s no way two new drives would have this problem unless Plextor’s QC is terrible.
