Now, what has me wondering is that it is the exact sector where we=20 switch to 48bit adressing mode. Anyhow, I've just checked on the old=20 Maxtor preproduktion 48bit reference drive I have here and it crosses=20 the limit with no problems. What controller are you using ? not all supports 48bit mode correctly.. --=20 -S=F8ren
