Sorry, I noticed this explain (= number of 0) was wrong
Maybe it should be
data = 0x800000;
sector = (data << 8); // 0xffffffff80000000
sector = (((typeof(sector_t))data) << 8); // 0x80000000
or
data = 0x80000000;
sector = (data << 8); // 0x0
sector = (((typeof(sector_t))data) << 8); // 0x8000000000
