I just upgraded to XP Pro, so I don't know if it has anything to do with it. My drive ( Creative 52X ) became erratic after the upgrade, now it won't read any discs. Auto start fires up when I put in a disc ( audio or data ) but then stops. If I use explorer to check the disc, It tells me to insert a disc. It appears as if the drivers, etc. are fine. Before I trash the drive, is there a way to check it out? I have a cat, I was wondering if I just need to clean the drive somehow, maybe it has cat hair blocking the reading laser or something. How would I clean or check that?
