Thanks very much to all who responded! I'm going to use Alan's 
suggestion first of all and if necessary a mixture of everyone else's. 
For good measure maybe I'll dump a pound or so of salt in a gallon of 
nice hot water and drop the hard drive in and wait for signs of rust to 
appear. Ha ha!

Thanks again!

Bob
