I am running Vista on my laptop. I haven't burned cd's in a while, and never used to have problems with it. When I recently tried to burn a CD, the entire burn/finalizing process completed without any error messages, but when I reinserted it into my computer, the CD was blank. I have tried various CD brands and tried WMP 11, Zune player, and Express Burn as my burners. I can still watch DVD's and play cd's, just not burn cd's. The TSSTcorp CD/DVDW TS-L632D ATA device is on my laptop, and all of its drivers are all up to date. Any help on what else to try? Thanks!
