I've checked Device Manager and the drive seems to be working properly. I've also tested out two installation/driver CDs and both of them worked. The programs I've tried to get the image file with are IsoBuster, Nero, and MagicDisc.
EDIT: Just wanted to give an update. I recently tried a third PS game as well as ImgBurn, but got nothing. In addition, I attempted to update the driver, but found that I have the latest one installed. However, the drive was able to detect two PS2 games (which are DVD-ROMs). So, maybe there's some kind of weird compatibility thing going on.
