The disk is fat32. I'm thinking this is the problem?

OpenProcess(PROCESS_ALL_ACCESS, true, pi.iProcessID);

OpenProcess(PROCESS_ALL_ACCESS, 1, pi.iProcessID);

First, you shouldn't be calling GetLastError() unless a return value indicates
an error actually occurred. If no error occurred, the return value of GetLastError()
is undefined in many cases. SetLastError() may have no effect if you're calling a Windows
API right after you use it. You have no idea how many times the error code for the thread may
change during that one API call.

Second, what do your marshaled structs look like? Are you marshaling them properly?

Third, you should be using IntPtr types for handles instead of int.
