Hi, I have the same problem with disks that were given to me (backup copy of my book) from my defunct publisher. The files are spanned over three disks and has a roxio restore icon on each disk. When I try to open Restore I get the message ""Disc Index File not found. To restore data, please open Roxio Restore from a spanned CD or DVD created with Toast." I am trying desperately to get a copy of Roxio Restore 1.0.5. which is the program icon on the disk. Anyone know where I can get a copy of Roxio Restore? Thanks so much.
