One more thing for this i just notic , if you are planing to buy a seagate , i suggest you go an look for the 7200.12 , because the company it self said that there are some problems inthere 7200.11 on the hard drives that 1TB but i don't remember if it's icluded the 500GB or not , any way , i have the "SEAGATE 350GB 3.5" HDD 7200RPM 16MB Cache 7200.11" but i'm using it as an out backup hard drives , because now i got the W.D black 640GB AALS
