I have to disagree here.  The day 10.4 came out I bought a new HD for 
my system disk, it had a defective spot on it.  If I'd zeroed out the 
drive I'd have found the bad spot prior to using it for two months. 
Once I filled up the drive to the point that I hit the bad spot the 
system freaked.  That is the main time I've lost data due to a HD 
failure in over 20 years.

I view zeroing the drive out as a good test of the HD.  It doesn't 
hurt anything, the downside is that it does take a long time with the 
big drives we have now.
