硬碟空間少了

文章monkey » 週二 10月 14, 2008 2:20 pm

原本是安裝雙系統一個是VISTA一個是XP

使用者不用VISTA都用XP

但是現在XP已經死當

用VISTA已經把檔案救出來

使用者說她想硬碟分2個就好

也不要用VISTA只要XP就好

我用SPFDISK去做分割但是還是沒看到少掉的空間

她的硬碟是250G現在顯示230G

20G就不見了

請問怎樣找出那部見的20G呢??

我試過不要分割

但是她上面顯示加起來也是230G

硬碟是WD牌子

我知道有些她們計算方式是1000M=1G

但是照這樣算起來也只是5G多爾已

還有不分割也是230G

SPFDISK也掃過了沒壞軌

你的算法有誤,
250GB的硬碟格式化後,
的確一般就是230GB左右,

粗算
250GB*1000 = 250000MB*1000 = 250000000KB
250000000KB/1024 = 244.140MB/1024 = 238.418GB

就你描述來看,沒問題。

PS:知道是一回事,真正知道又是一回事。 :wink:

那我知道算法了謝謝版主

好黑暗的硬碟

20G還可以放很多東西的說

現實世界黑錢電腦世界硬碟黑空間

買越大部就越吃虧

補充一下版主所述
電腦最基本運算單元為 0 和 1 ,如01001110,故稱2進位
例如
2的8次方=256
2的9次方=512
2的10次方=1024
硬體廠商為方便計算(硬ㄠ的說法),以10進位計數,
所以出現所謂誤差值:
硬體算法250G=250000MB=230G軟體算法
