Target Practice would actually leave portions of the disc 
intact and therefore readable through forensic processes.

Even writing ones and zeroes three times is not effective with 
the proper technology to recover the data.  Although it is usually 
sufficient for government purposes, and is the usual guideline.  
There is a procedure to recover erased data from disks that uses 
latent states of magnetism from of the original write on 
magnetic media.  (Go figure, the government sets the guidelines,
yet is one of the few organizations that can afford the
technology to recover erased data... hmmmmmmm.)

Assuming the client truly wants the data destroyed, a milling
machine set to remove the top layer of material (whatever it
is these days) would be the only 100% sure effective method
data destruction.  To keep yourself aboveboard, don't ask why
the client wants the data destroyed.

Or better yet (at least more fun), use them for target
practice.  I did this some years ago with the platters
from a 7933, and you can actually get a .45 slug to 
bounce off if you get the right angle ;-)

Then hang them on your wall with a label that says:

"head crash, bummer"
