I have the same problem with my NEC ND-3550A, and my old ND-2500A has this issue as well. Oddly, I noticed it seems to work with (and read) some old crappy Ritek DVD+Rs I have lying around, but none of the DVD-Rs I have of any type (including brand-new TY media) are really readable on either drive. Intermittently I’ll be able to see the disc, but it will get a device error while reading. The burns work fine in other stuff, and pass the CD/DVD Speed tests in my Asus DVD-E616A on the same computer with flying colors. They scan fine on my notebook and its noname DVD-ROM drive too.
I’m pretty frustrated by it, but the only thing I know to do is get a good reader like the Asus DVD-E616A. I’m at a loss for why the burns have low errors and good scans with my Asus drive but aren’t readable by the NECs.
I’ve used both Nero 6 and 7 to burn the discs and it doesn’t seem to matter. I’m going to pick up some TY +R media and see if that makes a difference, given the success in reading the old +R media I have lying around (though your comments make me think otherwise). Also, it doesn’t seem to make a difference if I burn with either UDF or ISO. The drive reads stamped DVDs and CD-Rs/RWs just fine.
I’ve no idea why it has such a severe reading problem for even its own burns. It’s a great writer, but man, I wish I knew how to resolve the reading issues.
I guess one thing I (and maybe you) can do is to try the drives in another PC, though I don’t have time for that at the moment.
At any rate, please let me know if you ever get the read issues figured out, I’d very much like to know. Until then, my only suggestion is the Asus DVD-E616A DVD-ROM drive, it seems to be the best reader from my research and is pretty cheap too.
