TestDisk是個體型嬌小卻功夫了得的磁碟分區檢查、搶救專家，不論你是因為手賤誤刪了磁碟分區，或是因為安裝作業系統、感染病毒而不慎毀損或遺失硬碟分區表，他都有辦法幫你救回來！TestDisk不但能夠在所有Windows作業系統下執行，還通包了NTFS、FAT、BeFS、BSD、DOS、HFS、JFS、Linux、LVM、UFS…等檔案系統。需要注意的是，在以TestDisk回覆磁碟分區前，不要進行磁碟分割或磁碟檢測，以免造成資料遺失。另外，若磁碟已格式化，就無法用TestDisk找回原本的分區了。



STEP
01. 將下載回來的「testdisk-6.3-win.zip」解壓縮，找到並執行置於「win」中的「testdisk_win.exe」。以上、下鍵選定硬碟後，選擇「Proceed」後按「Enter」。

02. 進入下一步驟後，選擇該硬碟的檔案系統類型，一般的Windows系統請選擇第一個[ Intel ]，最後按「Enter」即可。

03. TestDisk除了有「Analyse」選項可以分析現有分區結構和搜尋遺失的分區之外，
還有「Advanced」選項可以將分區設定成開機磁區或改變分區類型
、「Geometry」選項可以修改分區結構參數及大小
、「MBR Code」選項可以將主要開機磁區代碼寫入第一分割區。
在此以回覆遺失或誤刪的分割區為例，選定「Analyse」後按「Enter」，

04. TestDisk就會幫你找出所有磁碟分區，確定無誤後，以右鍵選擇「Save」後，按下「Enter」，最後再按「Quit」離開程式，重新開機後就可看到原本消失的磁碟分區了。

TestDisk is a powerful free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.

TestDisk can

    * Fix partition table, recover deleted partition
    * Recover FAT32 boot sector from its backup
    * Rebuild FAT12/FAT16/FAT32 boot sector
    * Fix FAT tables
    * Rebuild NTFS boot sector
    * Recover NTFS boot sector from its backup
    * Fix MFT using MFT mirror
    * Locate ext2/ext3 Backup SuperBlock
    * Undelete files from FAT filesystem
    * Copy files from deleted FAT, NTFS and ext2/ext3 partitions.

TestDisk has features for both novices and experts. For those who know little or nothing about data recovery techniques, TestDisk can be used to collect detailed information about a non-booting drive which can then be sent to a tech for further analysis. Those more familiar with such procedures should find TestDisk a handy tool in performing onsite recovery.
