I have Acronis True Image Home 9.0 Build 3677 on Windows XP SP2. I try to perform a full backup, and then at the beginning on the first disc I get a "disc full" error message. I get this same message with other discs, both DVD-R and DVD+R. The DVD burner is a Plextor PX-755SA, a SATA DVD drive. However, when I use my other DVD burner, Plextor PX-740A, a PATA DVD drive on the EIDE primary channel as a master, the backup works. I wonder if TI does not support SATA DVD drives?
