Yes it is their brand DVD and I did contact them several times. First they answered in this standard technical support way, which sounded like from a knowledge base (on your harddisk you find a folder applications and inside blablabla) and now they don't answer at all
I should have reformatted that drive immediately and copy my harddisk back. But I errouniously thought this is a bug in SuperDuper! and went in a wrong direction. I still think it's a bug, an enduser shouldn't see such kind of error - it leads to wrong assumptions.
SuperDuper! just stops working with that malloc Error, it would be better, if SuperDuper! would report which file makes the trouble and just leaves the problematic thing out and continues copying.
The problem is that I now have a backup in an unknown state, which will cause me to do much more work on that then would have been initially necessary.
Maybe I should try it with CCC or rsync, the later I probably can also control with a cron job.
