I have an Asus mobo p4b533-e with two WD disks in a raid 0 configuration (using the onboard promise tech card). I installed a CD burner, a regular DVD player and Life was good. I recently purchased a liteon on 16x dvd burner and it won't work in the asus Asus P4B533-E 1 Gig pc 2700 Memory 2 WD 80g drives mirrored 1 liteon cd RW 1 Matsumi (sp?) DVD 1 Lite DVD 16 X I tried anydvd and clonedvd2 I keep making coasters. I have updated the firmware on the dvd burner. About 3/4 of the way through it blows. I finally put the drive in a low end machine abit 550 with like a 10 gig drive (only 4.9 g free) , installed any dvd and clonedvd2 and it worked perfectly Same software, same media, same dvd burner, same o/s !!! I took the software to a friend's house, he has an asus too different model and it DID NOT work. What is UP with the asus box ... ? Do they have issues with DVD burning The config looks like IC Promise PDC20276, 2 channel IDE, supports ATA33/66/100/133 & RAID 0, 1 with a support of up to 4 ATAPI-devices" and "2 channel UltraDMA/100/66/33 Bus Master IDE (supports up to 4 ATAPI-devices"
