Now, what has me wondering is that it is the exact sector where we switch to 48bit adressing mode. Anyhow, I've just checked on the old Maxtor preproduktion 48bit reference drive I have here and it crosses the limit with no problems. What controller are you using ? not all supports 48bit mode correctly.. -- -Søren
