Dear Friends, I also would like to have a backupt of my B4 CD. But my Roxio CD copier aborts the copy process. I tried at two computers. In the one with Windows Xp, it even locks it up. The WinOnCD mentioned must be different in that it allows 'ignore error' when copying to image. WinOnCD is refered as another Roxio product. Will wait on the issue unless someone has some other tips or I can get the WinOnCd software. Thanks, Roel.
