安裝Microsoft Windows OS 硬碟限制

目前HDD 2TB的限制主要來自於硬碟分割技術(MBA and GPT),如使用舊有MBA方式分割硬體就會有些限制,如你使用HDD 已大於2TB 請使用GPT方式來分割
使用情況有二種如果需要Primary Partition 大於2TB並作為開機使用請檢查是否已滿足下列必要條件 :
1.使用 UEFI  
2.作業系統支援GPT 分割區

以目前產品來說XP Professional XPEPOSReady 2009確定Boot partition 無法大於2TB size.
如果無法滿足上述條件,可將開機Partition 大小限制於2TB之下. 再進行HDD 安裝.
你提供的硬碟速度變慢情況,請確認你硬碟是否有作4K alignment.
