I've been using a Liteon dvd-rom and LG GSA 4160B for a while and no problem. Now my LG wont burn to DVD-R. It will burn DVD-RW and DVD RAM (haven't tried DVD+R yet). Blank DVD-R disc properties come up as file system RAW but no available space. The drives will read DVD-R. When I attempt to burn a DVD-R the writer hangs and I have to turn off pc. Have uninstalled all burning software and re-installed individual programs to minimise compatability problems. Have tried Nero AnyDVD and CloneDVD2, Have uninstalled the drives and let XP re-install and still the same. So now I have purchased an ASUS DRW-1612BL, updated firmware. The problem remains. I'll also mention I have installed InCd on this machine and then removed it, whether this may be a culprit I am unsure. Can someone give me some help on this? I am currently using TDK DVD-R 1-8x Thought I might have a bad batch of DVD's (but half of them have worked and now they just wont) Bought some new TDK DVD-r 16x, but the problem is still there.
