Well, it seemed to work well with DVD reading and writing. Burned a movie onto a Princo -RW, and was able to play it on my set-top DVD.
Then I burned a CD-R with no problems. Then, later I tried burning a CD-RW. About 80% done, Nero quit with a Write Failed error. I tried erasing, and re-using the same disc, failed at about the same place. This was using a Verbatim High-Speed CD-RW disc. It's worked fine in other drives I've tried it on.
So, I tried an Imation CD-RW I had. Tried to erase it, the erase dialog box just disappeared after 10 seconds or so. Drive didn't eject disc. Tried another Imation, LED on drive just turned off completey a few seconds after inserting disc, Nero/XP both reported no disc present.
Had a new, unopened Verbatim High Speed CD-RW (4-10). Put it in drive, after 30+ seconds LED changed from yellow to 2 Amber blinks, then a pause, then repeat. Tried stamped CD-ROMs, the CD-R that it burned a few hours earlier, other known good CD-R's - nothing. It no longer reads/writes CD's. (I did try rebooting/powering off drive several times during all this, no help.)
It still appears to read/write DVD's fine, though. I took the drive to work, and I'm burning a DVD+RW right now.
Glad I bought it locally, it's going back to BestBuy. I'll try another if they have any more left. Haven't seen a DOA optical drive in over a year, and that one was a DOA plex too. (24-10-24) Fortunately, I still have the NEC ND-1300A.
For what little it's worth, this drive was made in Japan, I've seen threads at CDFreaks with comments about most of their drives being made in china.
And Plextor, if you're reading - why isn't PlexTools on the software DVD that comes with the drive? It's got the old Plex Manager 2000. $300, and I don't even get PlexTools?
