My M27C800's used to burn fine, but they all of a sudden quit programming. The adapter is fine, as I can burn M27C160 and 322's just fine. I have several 800's from 3 different places. I have the True USB v3

What I mean by quit, is they used to work fine...but they no longer program, and I have received chips from several different places and they still wont burn. Here is the message im getting:

Write failed, Address=0x000002, Buffer=0x02 Device=0x00

I have verified that they are blank
