Hello,
I am currently starting to dump my old PC and Mac Floppies, CDs and DVDs (Games, Software, Magazine). Look like some of them are missing or unconfirmed in the redump database. I've bought a Plextor PX-760A for CD/DVD-ROM. I am also lucky to have a first hand SH-D162C (GD-ROM & XBOX) and a first hand GGC-H20L (HD-DVD & BluRay) that never reads an HD disc.
