[DM-MUG] why will restore from backup not complete? Dead

[Ray Bowler]

Thanks to Alan and Matt for their replies. SMART says everything is 
fine. I used Disk Utility to zero free space and it stopped part way 
through. Used the security zero to zero all data and when it was part 
way through it ended with a failure. I had to use the regular erase 
to get it to mount. I used TechTool Pro to scan the surface and part 
way through it found the bad block. Apparently the system cannot tell 
it to ignore this block so it is a problem.

I am assuming that a new drive is indicated.
