Do just this, and no software-based recovery tool will ever see all your 
data again.  You might get some pay-dirt if you can release the locked 
out bad blocks...and there are some...and y contain data that is useful 
in small chunks (and yes, some data is).

If you think about the claims of data recovery from zeroed disks, they 
basically imply there is astronomical storage capacity in drives that is 
not tapped...and I do not believe the manufacturers have been holding 
out on us.  It may be possible to get hints of data, but with massive 
error rates and gaps.

If you are worried about recovering data after a single pass of writing 
zeros to the entire disk, you need to grind up or melt down the disk. 
If you are convinced there is (or will be) mysterious technology that 
can recover zeroed disks and your data is that interesting to these 
people, you don't know the abilities of it, so don't assume process X 
will keep your data deleted and never recovered.
