I don't know how many posts I have seen recently that have "carefully scrape the D0 surface" followed soon after by "I did that and now my xbox frags without the modchip installed".
The top D0 is very small and easily damaged, but I think some people's definition of 'carefully' is gouging into it with a pocket-knife!
A bit of advice - if your top D0 is covered by resin, use the Alt-D0 instead. It is much easier, larger and does not require any scraping. Otherwise you risk totally stuffing tour xbox.
