I've only had my 24x less than a week...I have tried the cd's that came with the drive no problem, some Fuji's and Walmart cheapies called "Durabrand".....they are their 24x cheapie 50 spindle. I'm sticking with Fuji's for important stuff, and the Dura's for quick copies.
I've used Nero and Discjuggler no problem. Unfortunately I've been having some probs with CDRWIN3.8E, and 4.0A doesn't even recognize my drive, while 3.8E does! My ASPI drivers are 4.60..uptodate.
