I just got the same drive and have just about given up being about to use CDA (and unfortunately all of my CDP projects!) with it at all. CDP Burn freezes needing a reboot as soon as you push the write button, Premaster pops of a "Write Error." dialog and then hangs (also needing a reboot), and although it recognizes the drive is there using the MMC driver burning straight from CDA produces a technically complex sounding drive error (haven't bothered to write it down). The CRW-F1 is an awesome CD burner, even better than the Plextor 12/10/32a I replaced (which just wore out), but it looks like I'm finally going to have to throw in the towel on CDA since it is no longer compatible with my hardware or OS. I'm running Windows XP SP1.
