Sounds like it's a problem just reading cheap media then, but if it's a new drive you may wanna complain to Plextor about it.
And be warned, just because a disc is name brand doesn't mean it's not a cheapo from Taiwan. I've got 100 TDK CD-Rs here that are made by Ritek in Taiwan. You can check the manufacturer of the disc by putting in a writer and running
CDR Identifier on it. I love this program. It shows me what kind of junk they're trying to fob off on me under their
brand name!

In order for the program to work you have to have an ASPI layer installed, and many people use
ForceASPI17 (when they can find it - it's tough 'cause Adaptec sucks) to install one. And who knows, maybe it'll make your problem go away, but there's no guarantee. Anyway, you can at least get Aspi Check from that guy's site and see if your ASPI layer is up to snuff, and if you search real hard on Google.com for five seconds you'll come across a site that has it but I wouldn't know anything about that....

Hey, where did that come from?! :Q
In the meantime you can do other things like going into device manager and making sure that the IDE channel the drive is connected to is set to use DMA if available for the Transfer Mode (properties/Advanced Tab), and it probably is.
(Pressed just means a commercial CD, which are pressed in a mold, not burned (which would take too long when you're making thousands of discs! Music CDs and store bought programs are on pressed CDs.)
