I wrote some code for the 8515 specifically to test for that old EE corruption issue. 
I never did get a hit. 

I suspect a lot of that was people starting writes immediately before a reset, or brownout. 

I do agree, set EEAR to zero when it's not in use, and don't use location 0.
It's cheap insurance.
