I’ve finally had success with writing to and restoring from a DVD with Promise 378 RAID 0. I’m using TI 8 Build 774. I booted from the Rescue CD. The difference between this attempt and other attempts was that I updated my Roxio Drag to Disc. I’m running version 126.96.36.199. Yeah… Yeah… I know, I should have bought NERO. At any rate if any of you are still having problems with your Promise Raid configurations and reading/writing from DVD try updating your UDF packet DVD-writing software.
